• Move OS from RAID5 array to RAID 1 arrays

  - by Antoine

  I want to give a last boost to my old ProLiant ML350 G5 server which just needs to be reliable for a few more year only ! With a defined budget of about 1500$ (I do not have more), i plan to replace the CPU (+ adding a second one), the battery cache of my raid controller (E200i), double the RAM, and change all hard drives. I have 7 HDD (SAS 10krpm, 72Gb) + 1 spare in RAID5, and my system is all FULL (no empty tray, full disks). in my current RAID5 array, I have 2 partitions: - 1 OS partition, 20Gb - 1 data partition, 350 Gb I plan to replace these 8 disks with : - 2 x 300Gb SAS 15krpm in RAID 1 (= 1 partition for OS) - 2 x 2Tb SATA 7.2krpm in RAID 1 (= 1 partition for DATA) My biggest constraint is that I have only 01 day to upgrade my server. Therefore, I'm looking for cloning all my files (OS + data partition) to my new arrays, i.e : - the OS partition shall be cloned to the RAID1 "2x300Gb array" - the data partition shall be cloned to the RAID1 "2x2Tb array" My second problem is that I need to physically remove all the old hard drives before inserting the new ones. I'm running Windows Server 2003 R2, and even if MS support will expire soon, I cannot buy a new licence and spent time in configuration. Obviously, with 1500$, I cannot also buy a new server that I could start configuring from now ! Thought about ASR (NTBackup), but I have no floppy drive (and do not really want to invest in one !) Thought about a clonezilla clone, and read this interesting link : Windows Server 2003 - move C: partition to a new SAS disk , but i'm not so confident in using Clonezilla with RAID5. What should be the best option to quickly and easily (if possible!) "copy/paste" my OS (so no need to reinstall and reconfigure all) and DATA / programs / services, etc... ? Thanks for your comments

• Known USB 2.0 devices don't install driver, but must be manually forced

  - by Darragh

  When a known USB 2.0 device is plugged in and detected, it doesn't install the driver correctly but shows a Code 28 error and lists the device under "Other Devices" in Device Manager. When view properties of this device , it shows the following status; The drivers for this device are not installed. (Code 28) There is no driver selected for the device information set or element. To find a driver for this device, click Update Driver. When updating the driver manually and selecting the appropriate driver Windows doesn't believes it's the correct driver, but you can force the installation and it works! The other condition the driver will auto-install is when the same USB device is plugged into a USB 3.0 port. Power related issues are not also causing this as I have tried vi a Docking station, USB hub. etc.. Devices tried; Jabra Headset USB-Mass Storage Device (flash disk and ext HD) MS Wireless Keyboard & Mouse USB Ethernet controller (USB-MAC controller) This is on a laptop part of a Domain with Windows 7 Ent 7601, I am logged in as a local administrator. There isn't any Group Policies blocking not signed driver or whitelisted devices on the domain. Any suggestions please feel free

• Host multiple domains with Apache on a VPS

  - by Kunal

  Hi I have recently bought a windows VPS and installed apache, mysql using xampp. All services are running fine. I can access the hosted site using the IP of VPS but what I need to do is host multiple domains on that server. Actually my requirement was to use htaccess on a php based site but the site had to access data from ms sql server as well. So needed to enable php_mssql.dll in the php.ini which no shared hosting was supporting. Had to go for this VPS. Plesk was installed by default but as htaccess wont work with IIS, I had to stop IIS service and install apache there. Now all is well, but I need to find a way to host multiple domains there. When I bought the VPS they hosting people sent me the dedicated IP of the server and also I have the 2 name servers required to host domains. What is the next step? Exactly which file I need to modify to get things done? Please help! Any kind of help is much appreciated. Thanks in advance for all of your kind help and time.

• Orphaned SQL Recordsets/Connections with IIS

  - by Damian

  I have an IIS 6 site running on Windows 2003 Server x86 with MS SQL2005 Enterprise edition running ASP Classic (no choice). The site runs very fast with about 8000 page views per hour. All of my SQL tables are indexed and I have used the profiler to check my queries, the slowest of which is only about 10-15ms. I have autoshrink disabled, autogrow is set to 250mb, database is 2gb with 800mb of free space. My problem is that every now and then the site will slow to a crawl for no reason. Pages that just have a simple 'connect to databse and increment a hit counter' work ok, but more SQL intensive pages that normally execute in about 60ms take 25,000ms to run. This happens for about 30 seconds and then goes away. I was having an issue with orphan recordsets and connections due to the way I was releasing them. I have fixed this up and the issue is much better, but I am still getting them. Is there a way with permon, etc. to track when SQL Server or Windows closes these Orphan connections? At least if I can monitor the issue I will know if I am making progress or if I am even looking at the right things. Is there anything else I might be missing? Thank you!

• UACCEEventLog 301 Filling Event Logs

  - by rjt

  After pushing out clients for the MS Application Compatibility Toolkit on our domain via GPO, UACCEEventLog 301 occurs a few times per second in the event log. Several Thousand per hour. One test i need to do is logon with Administrator to see if these events go away while Admin, but of course that is not a fix. This is only part of the event log entry, but is the most readable and clearly indicates yet another problem with Antivirus software. But still no fix. Originally, i posted this In Words and Bytes, but then edited it to make it much easier to read. LocalMachine\Users do have Read Access to this key. For a test, i added "Domain Users" but there are many more events for other parts of the registry and for Administrators. <XML> <TYPE> UacceRegistryVirtualization </TYPE> <EXENAME>smcgui.exe</EXENAME> <EXEPATH>c:\program files\symantec\symantec endpoint protection </EXEPATH> <APINAME>RegOpenKeyA</APINAME> <REGKEYNAME> HKEY_LOCAL_MACHINE\SOFTWARE \Symantec\Symantec Endpoint Protection\AV\Storages \SymHeurProcessProtection\RealTimeScan\0 </REGKEYNAME> <RESTRICTEDBYACL>FALSE</RESTRICTEDBYACL> <DESIREDACCESS>MAXIMUM_ALLOWED</DESIREDACCESS> <REGVALUENAME></REGVALUENAME> <REGVALUETYPE>0x00000000</REGVALUETYPE> <REGVALUEDATA></REGVALUEDATA> <CURRENTGROUP>Users</CURRENTGROUP> </XML>

• CIFS Mounting Permissions

  - by malco

  I have an issue that I;m going round in circles with, I hope you can help. The Set up: Server 1 (CIFS Client) - CentOS 6.3 AD integrated uing Samba/Winbind & idmap_ad Server 2 (CIFS Server) - CentOS 6.3 AD integrated uing Samba/Winbind & idmap_ad All users (apart from root) are AD authenticated and this, including groups, etc works happily. What's working: I have created a share on Server 2: [share2] path = /srv/samba/share2 writeable = yes Permissions on the share: drwxrwx---. 2 root domain users 4096 Oct 12 09:21 share2 I can log into a Windows machine as user5 (member of domain users) and everything works as it should, for example: If I create a file it shows the correct permissions and attributes on both the MS and the Linux sides. Where I Fall Down: I mount the share on Server 1 using: # mount //server2/share2 /mnt/share2/ -o username=cifsmount,password=blah,domain=blah Or using fstab: //server2/share2 /mnt/share2 cifs credentials=/blah/.creds 0 0 This mounts fine, but.... If I log su, or log onto server 1 as a normal user (say user5) and try to create a file I get: #touch test touch test touch: cannot touch `test': Permission denied Then if I check the folder the file was created but as the cifsmount user: -rw-r--r--. 1 cifsmount domain users 0 Oct 12 09:21 test I can rename, delete, move or copy stuff around as user5, I just can't create anything, what am I doing wrong? I'm guessing it's something to do with the mount action as when I log onto server2 as user5 and access the folder locally it all works as it should. Can anyone point me in the right direction?

• RPC Server Unavailable on Hyper-V cluster when moving resources after the host adapter has failed

  - by Doug Luxem

  On a Windows 2008 R2 SP1 cluster running Hyper-V, a lost network connectivity on the primary host interface. The interface was rapidly flapping up and down, and this was later determined to be caused by a faulty switch port. As this was a clustered server, the host interface was not fault tolerant (seeing as how the whole server was fault tolerant), so connectivity to the host was going up and down. The Hyper-V guests were completely unaffected by the network outage as they used a dedicated trunk on the server separate from the host interface. Additionally, dedicated interfaces for the cluster and live migration networks were fine. In order to diagnose the server, I tried to move all resources (Hyper-V Guests) to other nodes through Failover Cluster Manager. These moves failed with an error RPC Server Unavailable. The only way to move resources was by shutting down the guests, stopping the cluster service on the Node A, allowing other nodes to take ownership of the resources, and restarting the guests. A few other notes: All nodes have Client for MS Networks and File & Printer Sharing enabled on the Cluster and LM networks. Node A was accessible over cluster and LM networks from other nodes (these are private, cluster-only networks); pingable, CIFs, etc. Accessing \\NODEA is done over the Host adapters, as you would expect in this case and is the reason for the RPC Server Unavailable error with that adapter being down. My questions here are - Is there a way to still use Live Migration in a failure scenario such as this to prevent shutting down the Hyper-V guests? How can the network be reconfigured in the future so that the cluster service attempts to use the cluster and/or live migration networks to issue the RPC requests?

• LDAP SSL connect problem

  - by juergen

  I set up a test domain for my LDAP SSL tests and it is not working. I am using Windows Server 2008 R2 SP 1. I came so far: 1. i generated and installed my self signed certificate on the test domain controller 2. on the server i can log into ldap over SSL with the MS ldp.exe tool. 3. using ldp.exe on a client that is no in this domain the login fails with error 0x51 = "failed to connect". (i don't have a client computer that is in this domain right now) 4. I testet the certificate by using it in the IIS on the test server and I can reach the default page of the test server over SSL. (from the client that is not in the domain) 5. analysing the traffic between client and server I can see that the server is sending a certificate to the client. why isn't this working on my client computer?

• Distributing processing for an application that wasn't designed with that in mind

  - by Tim

  We've got the application at work that just sits and does a whole bunch of iterative processing on some data files to perform some simulations. This is done by an "old" Win32 application that isn't multi-processor aware, so new(ish) computers and workstations are mostly sitting idle running this application. However, since it's installed by a typical Windows Install Shield installer, I can't seem to install and run multiple copies of the application. The work can be split up manually before processing, enabling the work to be distributed across multiple machines, but we still can't take advantage of multiple core CPUs. The results can be joined back together after processing to make a complete simulation. Is there a product out there that would let me "compartmentalize" an installation (or 4) so I can take advantage of a multi-core CPU? I had thought of using MS Softgrid, but I believe that still depends on a remote server to do the heavy lifting (though please correct me if I'm wrong). Furthermore, is there a way I can distribute the workload off the one machine? So an input could be split into 50 chunks, handed out to 50 machines, and worked on? All without really changing the initial application? In a perfect world, I'd get the application to take advantage of a DesktopGrid (BOINC), but like most "mission critical corporate applications", the need is there, but the money is not. Thank you in advance (and sorry if this isn't appropriate for serverfault).

• How to pin "Visual Studio 2010 Documentation" shortcut to Windows 7 taskbar?

  - by Chris W. Rea

  I just installed Microsoft Visual Studio 2010 at home, on my Windows 7 PC. One of the items installed with VS2010 is "Microsoft Visual Studio 2010 Documentation". I like to have the documentation installed locally and at my fingertips, and so before had always added a shortcut for the help viewer to my Quick Launch toolbar. However, I'm not able to pin the new documentation to the Windows 7 taskbar. It's frustrating. Note carefully: When I launch "Microsoft Visual Studio 2010 Documentation" from the Start menu, it seems to perform two functions: First, it launches the "Help Library Agent", which is a local HTTP server from which the help content is served... similar to the local ASP.NET web development server. Second, it launches the default web browser against the localhost URL corresponding to the port on which the "Help Library Agent" is running, for example: http://127.0.0.1:47873/help/1-1444/ms.help?method=f1&query=msdnstart&product=VS&productVersion=100&locale=en-US ... in other words, the program doesn't leave behind an active foreground process that displays in the taskbar. So, I can't choose "Pin this program to taskbar" as one might do so with a typical program. How can I get a shortcut to "Microsoft Visual Studio 2010 Documentation" in the Windows 7 taskbar? Has anybody got a workaround for this?

• QR Codes Printing, but Not Printing Correctly - Any Ideas?

  - by SDS

  I am mail merging some QR codes via file paths stored in Excel into a label template in MS Word 2013. I have the whole process with the Ctrl+F9 working properly, but I am stumped on this: On the 30 label sheet I am trying to print I have 6 labels that are repeating information, and stored in duplicated rows in Excel for this print job. All of the labels have 2 images on them, one is a logo and the other one is a unique QR code for that person. For the first set of 6 labels that print out, everything works perfect. However, from the 2nd time the information is printed onward all of the merged fields and logo look correct, but the QR codes are printing strangely. Basically it's the QR code as I want it, but with a copy of itself covering the top left 25% of the QR code. Print preview doesn't show this happening, only once it's printed does it come out like this. I've been trying everything I can think of to fix this and don't know what to do. So far I've: Recreated the document several times, tried duplicating the images in the source folder and giving the links in the Excel document new file paths in case the mail merge feeding from the same .jpg was an issue (even though it's not a problem with the logo) Any help or insight is greatly appreciate because this is a test run for a larger batch run that I need to get done soon :( Thank you!

• Catastrophic Failure opening ODBC via Citrix

  - by Joshdan

  We recently had our Citrix server crash unexpectedly. When it came back up, there was a new issue -- every ODBC connection fails with "Catastrophic Failure" (0x8000FFFF). The issue is limited to Citrix / ICA connections; logging in as the same user via RDP works as usual. The following code is my minimal test case (for wscript): ''// test_odbc.vbs strConn = "Driver={Microsoft Text Driver (*.txt; *.csv)};Dbq=c:\files\;" Set rs = CreateObject("ADODB.recordset") strSQL = "SELECT * FROM myFile.csv" wscript.echo "Press OK to Test" ''// This line breaks over Citrix, but not over Terminal Services ''// ---------------------- rs.open strSQL, strConn, 3,3 ''// ---------------------- wscript.echo rs("a") Any insight would be greatly appreciated. Windows Server 2003 SP1, Citrix MetaFrame Presentation Server 4.0. Clients include at least versions 10.2-11 running on 2000-Vista, OS X. ODBC error happens whether a DSN is used or not, on at least Access, MS-SQL, and CSV. Connections both through the SSL Gateway and directly. There have been a few users actually able to log in without trouble, but I can't pin down anything special about them.

• Finding default gateway in an openvpn environment in windows

  - by Alexander Trümper

  I need to find the default gateway in a openvpn scenario where the route output looks like that: IPv4 Route Table =========================================================================== Active Routes: Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 10.49.73.1 10.49.73.24 10 0.0.0.0 128.0.0.0 10.8.0.1 10.8.0.2 30 So I googled around a bit and a found this script here: @For /f "tokens=3" %%* in ( 'route.exe print ^|findstr "\<0.0.0.0\>"' ) Do @Set "DefaultGateway=%%*" echo %DefaultGateway% This works, but matches both lines in the route output. But I need to find this line: 0.0.0.0 0.0.0.0 10.49.73.1 10.49.73.24 10 So I tried to modify the findstr parameter like this: findstr "\<0.0.0.0\>.\<0.0.0.0\>" in the expectation that '.' will match for the tab between the columns. But it doesn't. It will still set DefaultGateway to 10.8.0.1 I couldn't find a clue in MS documentation either. Maybe someone knows the right expression? Thanks a lot.

• Acrobat 9 Pro - shortcut key failure

  - by Rick G

  I create numerous Acrobat PDF files from MS Word documents via Acrobat 9 Pro. I often need to print a single page from an Acrobat PDF file. I normally use the keyboard shortcut Control-P (Print Dialog) and ALT-U (current page). I recently set up a new PC with Windows 7, and this shortcut combination does not work. When I press ALT-U, it moves the highlight to the correct item, but does not select the radio button. If I press the Enter key, then I print the entire document instead of the current page - VERY annoying! It looks like there is an error in the design of the Print dialog for Acrobat. There are two items which have ALT-U as the keyboard shortcut. They are "Current page" in the Print range frame, and "Summarize comments". I have been able to use Control-P (Print Dialog) and ALT-U (current page) with no problems on virtual machines and older computers running Windows XP. Maybe I installed some software on the new PC that is messing up the keyboard shortcut. Is there any way to figure out the culprit - or is this a known problem with Acrobat?

• very slow internet with Linksys WRT54GL only in wireless mode (wired is OK)

  - by gojira

  I bought a new Cisco Linksys WRT54GL router to connect my laptop (running Windows 7) to the internet. I installed Tomato 1.28 firmware on the router. When I connect the laptop to the router via ethernet cable, everything is fine and I get extremely fast up- and download speeds. When I connect wirelesssly however, websites load extremely slow - it takes dozens of seconds to load a website! <-- This is my question, how can I fix the wireless speed issue? Gmail for example is unusable this way. I tried speedtest.net, but this always fails in the upload part of the test so I can't even test the bandwidth (could the fact that it fails in the upload part, not the download part, be an indication what the problem is?!). I have isolated the problem a bit, I am convinced it has to do either with the router itself, the router settings, or the settings of the wireless connection in Win 7. Because previously, I was using another router by Buffalo and I had no problems whatsoever. I have tried to reproduce the settings from the Bufallo router as closely as possible on the Linksys router (same channel, same encryption etc). The download speed problem only occurs with the Linksys router, and only in wireless mode! When I exchange the Linksys router with the Buffalo router I have here for testing, the wireless speed is up to normal again. Also, before I had installed the Tomato firmware I had exactly the same problem, so it has nothing to do with the firmware itself. Notes & things I already tried: Changing the channel: does not seem to affect anything, I am also on the same channel (10) which I was previously on when I had a Buffalo router. QoS is off. Ping to the router itself is OK, ~ 1 ms. Some current settings of the linksys router: WAN / Internet Type: DHCP Wirelesss Mode: Access Point B/G Mode: Mixed Broadcast: check Channel: 10 - 2.457 GHz Security: WPA2 Personal Encryption: AES

• Menu command stuck on screen

  - by 280Z28

  For some reason, periodically when I select a menu command, the command label gets "stuck" on the screen and won't go away. I can close all open applications, including whichever one I was using when it got stuck, but it still won't go away. In the screenshot below, I opened an new instance of IE just to show how the label stays on top. The label was not created by this instance of IE. Edit with the source: The label that gets stuck is the first menu command I select in IE. If a label is already stuck, a new one does not get stuck (regardless of which instance(s) of IE are involved). Based on this knowledge, I now just open IE on my secondary monitor, carefully open the context menu so the Properties command is in the bottom corner, and click it. This is not a solution... The label never moves and is transparent to mouse input (if I click it, it's as if I clicked the item behind it). The label does not go away if I close all running applications. I haven't tried stopping services or closing system tray items like Live Mesh. The label does go away if I change the screen resolution and then change it back. Any ideas how I can stop this from happening? It's happened a half dozen times since yesterday and it's becoming quite disrupting to my work. Obviously I added the circle in MS Paint. That part isn't stuck. ;)

• TLS_REQCERT and PHP with LDAPS

  - by John

  Problem: Secure LDAP queries via command-line and PHP to an AD domain controller with a self-signed certificate. Background: I am working on a project where I need to enable LDAP look-ups from a PHP web application to a MS AD domain controller that is using a self-signed certificate. This self-signed certificate is also using a domain name that is not a FQDN - think of something like people.campus as the domain name. The web application would take the user's credentials and pass them on to the AD domain controller to verify if the credntials are a match or not. This seems simple, but I am having problems trying to get PHP and the self-signed certificate to work. Some people have suggested that I changed the TLS_REQCERT variable from "request" to "never" within the OpenLDAP configuration. I am concerned that this might have larger implications such as a man-in-the-middle attack and I am not comfortable changing this setting to never. I have also read some places online where one can take a certificate and place it as a trusted source within the openldap configuration file. I am curious if that is something that I could do for the situation that I have? Can I, from the command line, obtain the self-signed certificate that the AD domain controller is using, save it to a file, and then have openldap use that file for the trust that it needs so that I do not need to adjust the variable from request to never? I do not have access to the AD domain controller and as a result cannot export the certificate. If there is a way to obtain the certificate from the command line, what commands do I need to use? Is there an alternate method of handling this issue that would be better in the long run? I have some CentOS servers and some Ubuntu servers that I am working with to try and get this going on. Thanks in advance for your help and ideas.

• How to better copy&paste big files over RDP?

  - by WebMAOhist

  Recently I was making a few attempts to copy&paste a big (1.2 GB) file to remote computer over RDP. The remote computer is virtual testing machine with MS Windows Server 2008 Datacenter. First I tried to copy&paste before midnight when the transfer speed was limited by client computer ISP to 100 kB/s. So, it required a few hours and I was forced to cancel transfer since remote desktop became too unresponsive and sluggish (slow). So, I re-started it over midnight when my local transfer speed is over 4 GB/s 4MB/s (sorry for typo). So, my impression is that independently on speed (broadband) of copy&paste transfer the remote computer becomes sluggish while copying over RDP. At the same time downloading from internet doesn't make remote host sluggish. AFAIU, it is because clipboard of remote computer and so its memory becomes overloaded by transfer. How can I control (restrict) the usage of clipboard for specific process (pasting of file)? What are the possible way to control it? Update: After reading that slow speed of transfer is caused by encryption used for copy&pasting over RDP and since I believe I am more interested in overall efficiency: both the time, or rapidness, of getting file as well as possibility to work without waiting, I changed the question title from: How to control the usage of remote desktop clipboard usage for pasting a big file? to How to better copy&paste big files over RDP? For example, is it better to copy&paste one huge (zip) archive or unzip it and copy paste a folder with unzipped files? And more exactly I wanted to ask: What are possible ways to improve overall experience: the speed of transfer (i.e. availability of needed file) responsiveness of remote host (making remote coputer available for work before completion of copy&pasting)?

• Can't access Port 80 from external

  - by dewacorp.alliances

  Hi there I have configuration like this: NETGEAR MODEM LINKSYS ROUTER SERVERS In the modem, I've setup as bridging and all the traffic is controlling by this ROUTER. Prior to this setup, I can access website from external (port 80) plus exchange servers (mail) and https. But now with this configuration, I can only send/receive using Exhcange servers and access OWA (Outlook web access using port 443) .... and no internal websites from outside. This is my config for LINKSYS ROUTER Application | Start | End | Protocol | IP Address Ms Exchange | 25 | 25 | Both (TCP/UDP) | 192.168.100.8 Internets | 80 | 80 | Both (TCP/UDP) | 192.168.100.11 SSL | 443 | 443 | Both (TCP/UDP) | 192.168.100.8 Exchange | 110 | 110 | Both (TCP/UDP) | 192.168.100.8 192.168.100.11 is a UBUNTU web server that running the apache which controlling the virtual name (extranet, cms, test) to redirect to the different servers. As you can see, the home internet is only allowing public IP address. Now I test this schenarion in internal network work nicely. For instance. If I type in extranet.XXX.local it goes to the right applicatios or if I try CMS.XXX.local again it goes to the right one. I also asked to ISP just in case if they are blocking the inbound port 80 for unknown reason. They said no. So I didn't understand why this happens. I suspect the configuration that I have between MODEM ROUTER but I counldn't work what it is. I don't have a documentation of previous settings and I don't know if there is a port that I need to open as well. I am appreciated your comment

• Any dangers in using DDR memory with a higher frequency than the FSB?

  - by raw_noob

  I'm looking to upgrade memory in an older motherboard. The processor is an AMD Sempron 2500+ with a maximum speed of 333/166MHz. The motherboard is an MSI MS-7061 (KV3M-V), which accepts up to 2Gb of DDR memory maximum PC2700 in 2 slots and has a maximum FSB of 333MHz. The board does not have dual-channel support. Existing memory includes a stick of 512Mb PC3200, which seems to be running OK (presumably at PC2700) but is rated 200MHz, which is below the FSB speed. The other stick is 256Mb PC2100/133MHz, again below the FSB speed. (All figures from CPU-Z.) I have a chance to acquire a single used stick of PC3200/400MHz memory very cheaply. Crucial's system scanner seems to suggest that this will be OK with my system, but other sites have suggested that running memory with a higher frequency than the FSB can cause instability. Is this true? Would I be better waiting until I can buy the correct PC2700/333MHz stick? I'm assuming that the mixed memory I have at present is running as 768Mb at 133MHz. Is this a reasonable assumption? If so, would you expect the performance differences between 768Mb/133MHz and 1Gb/333MHz to be very noticeable? If I install the new 1Gb/400 or 333MHz stick in slot 1, am I right in thinking that adding back the existing 512Mb/200MHz stick in slot 2 would pull the whole 1.5Gb system memory speed down to 200MHz? If so, which would be better - 1.5Gb/200MHz, or the single 1Gb stick at the full 333MHz that the FSB permits? Is more headroom more important than extra speed? Any help - or even opinions - gratefully received. I can't find reliable information, and I can't afford to make expensive mistakes.

• Why does Windows Event Log stop logging events before maximum log size is reached?

  - by Tuure Laurinolli

  I have a service that produces a lot of event log output. Currently the event log is configured to overwrite any old events to keep the log from ever getting full. We have also increased the event log size considerably (to about 600 MB). Recently the service started reporting errors to its clients, and the error message it was sending to its clients is "The event log file is full". How can this be, when event log is configured to overwrite as necessary? In our hurry to get the service back up we cleared the event log without saving its contents, but most likely it had not reached 600 MB yet, judging from sizes of some earlier log dumps. There is also MS KB entry 312571, which reports that a hot fix to a similar issue is available, but the the configuration that the fix applies to is not exactly the same we have. Specifically, the fix only applies if event logs are configured to never overwrite old events. I wonder if this has something to do with the fact that the log files apparently are memory-mapped. What happens if the system runs out of address space to map files to?

• What is the max connections via remote desktop for a small server?

  - by Jay Wen

  I have a small server running MS Server 2012. The CPU is a Xeon E3-1230 V2 @ 3.30GHz, 4 Cores, 8 Logical Processors, 8 GB RAM. Main HD is a Samsung 840, and the big storage is a 4 disk WD Black Raid 10 Array in a Synology NAS enclusure. My question is: given this hardware, approximately how many users can the system support via "Remote Desktop Connection"? Assume there are no licensing limits. These are not admin users. I know there is a two admin limit. This boils down to: What resources does one remote connection require? RAM? % of the CPU? Networking bandwidth? I guess the base case would be for a conection where the user is inactive or simply browsing cnn. Once you know this, you know how many you could fit on the machine before something is maxed-out. In reality, users would be mostly on Excel (multi-MB spreadsheets). I know the approx. resources currently required by each copy of Excel.

• Windows Server - share files without access for administrator

  - by Pawel

  We have a MS Windows Server 2008 R8 based server that is administrated by our IT department. We would like to achieve two things simultaneously: A folder on the server, containing several thousand files (new files added frequently) that is accessible to some ActiveDirectory users (e.g. board of directors) but is not accessible by IT department employees IT department employees still maintain rights to administrate the server, including installing new software and services We already checked some solutions: Using NTFS access rights. Unfortunately IT (members of "Administrators" group) can set themselves as new owners of the files and change the permissions so that they gain access to the files. Enabling EFS. Unfortunately even if you do not allow IT to access files, they still can disable EFS completely because they have administrative rights. Moreover as far as I know you have to manually add permissions for all users but the owner for each new file - very inconvenient. Creating a new role for the IT department that has all the privileges apart from taking ownership of files. Unfortunately if you're not a member of the Administrators group, you cannot install new software, no matter what privileges you add to the role. TrueCrypt - nice free encryption software, but with poor sharing capabilities. You can either mount an encryption container on the server (and then IT has access to its contents) or you mount them locally but only one user can mount it for writing. AxCrypt - free encryption software that enables file-by-file encryption on the server. There are some disadvantages though - you have to manually encrypt each new file added. The files have their extensions changes. You can only set one password for all files (so all users have to know this one password). Any other ideas? Our budget is limited so enterprise-class software from Symantec or PGP would probably be not an option.

• How to view / enumerate / obtain a list of all effective rights / permissions on an Active Directory object?

  - by Laura

  I am new to Server Fault and was hoping to find an answer to a question that I have been struggling with for the past week or so. I have been recently asked by my management to furnish a list of all the effective rights / permissions delegated on the Active Directory object for our Domain Admins group. I initially figured I'd use the Effective Permissions Tab in Active Directory Users and Computers but had two problems with it. The first was that it doesn't seem very accurate and the second was that it requires me to enter the name of a specific user, and it only shows me what it figures are effective permissions for that user. Now, we have more than a 1000 users in our environment so there's no way I can possibly enter 1000 user names one by one. Plus, there is no way to export that information either. I also looked at dsacls from MS but it doesn't do effective permissions. Someone pointed me to a tool called ADUCAdmin but that seems to falsely claim to do effective permissions. Could someone kindly help me find a way to obtain this listing? Basically, I need to generate a list of all the modify effective permissions granted on the Domain Admins group object along with the list of all the admins to which these permissions are granted. In case it helps, I don't need a fancy listing - simple text / CSV output would be enough I would be grateful for any assistance since this is time and security sensitive for us.
