  • Remote hosts accessing AD's registry

    - by smitty user
    I have a situation here. I have an intrusion detection system and it constantly alerts me that a remote host is accessing our AD's registry remotely. Our remote hosts are mainly Windows XP and our ADs are W2K8. The remote hosts access them over SMB port 445 Is it normal for Windows hosts to access AD's remote registry? My colleagues confirmed with me that both host and AD is clean from virus with endpoint protection enabled. Thanks.

  • Filezilla FTP Server - Security Implications of its usage on Windos Server 2003

    - by Brian Webster
    I'm running Filezilla server on my dedicated windows 2003 server. It uses its own user-access control system. The Filezilla server service itself is running under the System user. When I setup users within the FTP Server Administrator Interface, I do not need to setup equivalent users, or adjust permissions on folders to allow users to login. Example: I setup TestFTP user with password 'p' I set the home directoy of TestFTP user to be e:/website I verify that e:/website only has permission for the System and Admin accounts (right click - security in windows explorer) TestFTP is able to login to the server just fine. I'm OK with this (perhaps due to ignorance?). Is it generally frounded upon to utilize a FTP Server such as FileZilla Server that bypasses the built-in UAC in this method? If I wasn't clear enough, please let me know.

  • 403 Forbidden when Deploying asp.net 4.0 site to IIS 7

    - by Jordan
    So I have an EC2 instance running, the URL NoWeatherSurprises.com I have the DNS pointing there, and I set up a new site in IIS 7 and pointed it to a folder. I used Visual Studios Web Developer 2010 express to publish to this folder. It now has the binaries and such. However if I go to NoWeatherSurprises.com I get the welcome to IIS 7 screen. I'd expect to go to my application If I navigate to http://noweathersurprises.com/weather/ [weather was the folder I published to under wwwroot] I get a 403 forbidden. I have no idea why, I am guessing that it is trying to do a directory listing or something instead of launching my MVC Application. So 2 problems in summary. It is not pointing the domain to the folder directly and I need to add /weather I am getting a 403 forbidden instead of the results of my home controller with the index action. I am new to IIS 7, I had been using IIS 6 and had a lot less trouble setting it up, but I suspect that's my own fault and i am just missing something. Thanks in advance for any help

  • Microphones not working on Apple macbook Air 1,1 (Early 2008) under Linux

    - by jj_p
    I'm running Linux on an mba. I can't make the microphones (neither external nor internal) work. I test using alsamixer and arecord -d 5 test-mic.waw together with aplay test-mic.waw It seems there is a problem with kernel trying to decipher Apple (intentionally) corrupted 'bios', in particular the mic pins are wrongly assigned. As far as we are concerned here, is there any difference between using EFI and BIOS-compatibility mode? (see https://wiki.archlinux.org/index.php/MacBook where they claim to have everything working out of the box on mba1,1) A nice proposal would be to compile the latest Linux kernel and run hda-jack-retask to find the right configuration (in the case of Realtek codec, the missing things I'm supposed to check are either some vendor-specific COEF verbs, EAPD or GPIO setup.), and then come up with a kernel patch to address the issue. Since I'm not that familiar with this last part of the story, can anyone help me through this process? Some useful data: The output from alsa script run as root http://www.alsa-project.org/db/?f=adae8ebee1007043fe83414ac4972319e02255fa The command hda-jack-sense-test -a (with external mic in) Pin 0x14 (Internal Speaker): present = No Pin 0x15 (Green HP Out): present = Yes Pin 0x16 (Not connected): present = No Pin 0x17 (Not connected): present = No Pin 0x18 (Not connected): present = No Pin 0x19 (Not connected): present = No Pin 0x1a (Not connected): present = No Pin 0x1b (Not connected): present = No Pin 0x1c (Not connected): present = No Pin 0x1d (Not connected): present = No Pin 0x1e (Not connected): present = No Pin 0x1f (Not connected): present = No Most likely the chip is Realtek ALC885 (compare also ALC889A) http://guide-images.ifixit.net/igi/bBTSqaeK5JpQ1AWe.large , although at the moment alsa reads it as ALC889A Takashi Iwai's tutorial https://www.kernel.org/doc/Documentation/sound/alsa/HD-Audio.txt Some people researched the original files from a running OS X installation on this same model (I think the relevant files are AppleHDA.kext/Contents/MacOS/AppleHDA AppleHDA.kext/Contents/PlugIns/AppleHDAHardwareConfigDriver.kext/Contents/Info.p????list AppleHDA.kext/Contents/Resources/layout12.xml.zlib AppleHDA.kext/Contents/Resources/Platforms.xml.zlib) http://www.insanelymac.com/forum/topic/220090-alc889a-pin-configuration/#entry1554954 Datasheet http://www.realtek.info/pdf/ALC885_1-1.pdf (from the same Realtek, one can also try to download Linux driver, but this is just taken from ALSA project, as stated in the readme file.) Compare with this Arch guy http://www.alsa-project.org/db/?f=3ca8243c0626844f0264a3faad0aa72018bc14f4 Here for the first time support to audio (except mics) for mba1,2 (which is morally the same as 1,1) is patched into the kernel http://www.alsa-project.org/pipermail/alsa-devel/2010-February/025511.html The same jack supposedly works both for HP and ext MIC, I think it's called TRRS, and it's the same as the one used e.g. for iphones This guy might have done a similar job, though to a more recent version and for sound globally, not just mics: http://blogs.aerys.in/jeanmarc-leroux/2013/09/15/fixing-2013-macbook-air-ubuntu-sound-issue/ (this is mirror to http://unix.stackexchange.com/questions/73044/microphones-not-working-on-apple-macbook-air-1-1-early-2008-under-linux )

  • Windows SBS 2011 DNS Role (service) failing & needing restarting

    - by HaydnWVN
    Have a Windows SBS 2011 with Exchange that is handling all DNS for the network. Since getting a 3rd party (Hardware & Support) to setup a recieving FTP service and restricting Exchanges memory useage for another 3rd party product (Stock software) the local network seems to periodically 'lose the internet connection'. Delving deeper I found that the DNS service is somehow failing/stopping without the actual service on the server reporting such (nothing in event logs). A simple restart of the 'DNS Role' on the server solves the problem. The manager onsite reports that he has to do this most days in the afternoon - yet not at the same time and other days it works fine without a restart being required. I'm unable (lacking sufficient SBS2011 knowledge) to diagnose this further, ideally I would like the DNS Role to report (and log) the failure, then automatically restart itself.

  • SharePoint 2010 not seeing Active Directory users

    - by user117927
    I'm pretty new to Active Directory and SharePoint but I was given to understand they are supposed to play well together. Now I have successfully set up AD with multiple user accounts that work on any member computer. I have also successfully installed SharePoint 2010 Server on an AD machine. Both the AD server and SharePoint servers are on separate machines (VMs running on ESXi to be precise). I can only log on with user accounts I create on the local server. Furthermore the user browser thing for adding users will only see local users. I've followed the advice here http://technet.microsoft.com/en-us/library/cc262350.aspx#section2 for Classic authentication and also NTLM claims based authentication but to no avail. Is there something fundamental I am getting wrong here? I'd be really thankful for any help you can lend me; I've been googling and scratching my head for a couple of days now. P

  • Hyper-V Virtual Machine Networking issues related to Max Ethernet Frame Size

    - by Goatmale
    I fixed an issue today earlier today but i'm interested in learning WHY it worked. We set up a new Hyper-V virtual machine only to discover that HTTP traffic wasn't working. HTTPS, pings, everything else was working fine. After months of prodding around I took a shot in the dark. On the Hyper-V host server, the physical NIC card had an advanced setting of "Max Ethernet Frame Size" set to 1500. After setting this setting to 1514 the issue was fixed. Alternatively, setting this to 1512 did not solve the issue; 1514 is the magic number. My best guess it that when this setting was set to 1500 it was allowing incoming pings because the data payload was a lot smaller of say, HTTP traffic. As far as HTTPS traffic, I read about something called "Path MTU discovery" which i'm going to assume why is HTTPs traffic was getting through fine, albeit slower. Looking at this post, people agree that 1518 is the max total frame size. Why didn't I need to change this to 1518 instead of 1514 bytes? Why is the default frame size 1500 if that's the max size of the Ethernet payload and not the max size.

  • Problem with network policy rule in Network Policy Server

    - by Robert Moir
    Trying to configure RADIUS for a college network, and have run into the following frustration: I can't set an "AND" condition for group membership of authenticated objects in the network policy rules, e.g. I'm trying to create a NPS rule that says, essentially "IF user is a member of [list of user groups] And is authenticating from a computer in [wireless computer group] then allow access. The screenshot above is the rule I am having trouble with. It does not work as written. The rule underneath it, which is identical in every aspect except the conditions rule, does work. I've tried changing the non-working rule to define each set of groups as "Windows group" rather than specifically as machine and user groups, with no change. With the "faulty" rule enabled and the working one disabled, any attempt to login with a valid account from a machine that is in the wireless computers group gives a 6273 audit event in the windows event log: Reason code 66 - "the user attempted to use an authentication method that is not enabled on the matching network policy". Disabling the "faulty" rule, enabling the other rule and logging in with the same account and computer works just fine.

  • Creating RAID1 on Windows Server causes not enough disk space error

    - by northpole
    I have three disks. Disk0 (boot), Disk1 and Disk2. Disk 1 and 2 are both unformatted and unallocated drives. I am trying to mirror Disk0 to Disk1. They are both Dynamic and are both the same size (1TB). When I select Disk1 to be the mirror I get the error "There is not enough space available on the disk(s) to complete this operation". I have spent several hours searching for a solution but have not found one. Why do I get this error when they are both the same size? EDIT: Shrinking the volume size on the boot disk by 100MB allowed me to get past this error. From what I read the mirror drive needs to be the same size or larger than the boot drive. So I am confused why that change worked. However, I now get the error " all disks holding extents for a given volume must have the same sector size and the sector size must be valid". I believe this is because the drives are different and one has 512B and the other is the Advanced Drive that is 4KB. What the different sector sizes cause both problems? If I got the same disks would both issues go away?

  • How to manage service failover?

    - by Jader Dias
    I am using Windows Network Load Balancing to keep my apps available even when one of the servers is down. But when all servers are up, but one instance of a service in one of them is down, I would like to not send requests to it, because those requests will be lost. Is there any solution that addresses this problem?

  • Current wisdom on SQL Server and Hyperthreading?

    - by BradC
    Lots of articles out there (see Slava Oks's original SQL 2000 article and Kevin Kline's SQL 2005 update) recommend disabling hyperthreading on SQL servers, or at least testing your specific workload before enabling it on your servers. This issue is gradually becoming less relevant as true multi-core processors replace hyperthreaded ones, but what's the current wisdom on this issue? Does this advice change any with SQL 2005 64-bit, or SQL 2008, or Windows Server 2008? Ideally, this should be tested in advance in a staging environment, but what about for servers that have already made it into production with HT enabled? How can I tell if performance issues we're experiencing might be related to HT? Is there some specific combination of perfmon counters that might point me in that direction, as opposed to all the other things I normally pursue when working on improving SQL performance? Edit: This is especially attractive because of the potential for an across the board improvement for some of my high-cpu servers, but the client is going to want to see something concrete that helps me identify which servers really could benefit from disabling hyperthreading. Of course, conventional performance troubleshooting is ongoing, but sometimes any little bit helps.

  • Kerberos Policy section not appearing in RSop / GPResult

    - by Chloraphil
    I am attempting to confirm via RSoP or GPResult that the correct settings for "\Computer Configuration\Windows Settings\Security Settings\Account Policies\Kerberos Policy" are being applied, however the "Kerberos Policy" node is missing from the treeview / report. These settings are set in the "Default Domain Controllers Policy" which is linked in the "Domain Controllers" OU. Should "Kerberos Policy" appear at all? If not, how can I confirm the correct settings are being applied?

  • Smss.exe - setting any core affinity breaks rdp on Windows 7 / Windows Server 2012

    - by Hetman
    I have tried to set core affinity of smss.exe to not run on one critical core on Windows 7 and Windows Server 2008r2. It turns out that simply setting the core affinity to anything (even the full mask that smss.exe already has) seems to work but prevents users from rdp'ing into the machine until it is restarted. The users already logged in may continue to use their sessions. This behaviour does not occur on Windows 8/Windows Server 2012. Does anyone know why it is happening?

  • How to make other computers connected to my workgroup able to browse my web server via my private local domain www.mydomain.local?

    - by Motivated Student
    Background I have a broadband connection. The fiber optic cable running from outside to my building is connected to a converter unit. The output of the converter is connected to a router. The router also provides 8 LAN ports to which the computers are connected. Shortly speaking, all computers are interconnected in a workgroup as opposed to a domain. My computer hosts an IIS web server using a private or local domain name www.mydomain.local. I has added 127.0.0.1 www.mydomain.local to the hosts file in the server C:\Windows\System32\drivers\etc so I can browse the site from within the server. So far so good. How to make other computers connected to my workgroup able to browse my web server via my private local domain www.mydomain.local? Note: Again, I am a newbie. I have no idea what I should do next.

  • HP DL380 G7 Disk swap to a HP DL380 G6

    - by rnuno
    The HP DL380 G7 has 3 SAS disks in RAID 5 configuration. I need to change that server to another task and instead of make a clean install on the HP DL380 G6 can i just swap the 3 disks from HP DL380 G7 to the HP DL380 G6? I expect some driver issues maybe on the OS itself because the processor is different. They both use Smart Array P410i, if i power down the machines swap the disk by the same order will the RAID 5 configuration remain and the OS will boot?

  • How to stop/kill a virtual machine that hangs in "Stopping" state?

    - by SvetP
    Hi, I have a virtual machine that constantly hangs in the “Stopping” state. I’ve red several posts suggesting killing the vmwp.exe process of the machine but I’ve never been able to kill this process neither from the Windows Task Manager nor from an administrative command prompt by using prockill /PID xxxx /F where xxxx was the process ID. The only result that I have is that my machine enters in “Stopping-Critical” state. Even worse, from that point (having a virtual machine hung at stopping) I am unable to manage (stop or start) any other virtual machine on the same host. The only “solution” in that case for me is to stop the Virtual Machine Management Service (vmms.exe) and to restart the physical host. Without first stopping the vmms.exe service my physical host also hangs during the restart. Moreover, there is no any error logged in the Event Viewer. I’ve found some other posts complaining about them problem. On all of them the only suggestion was to kill the vmwp.exe process, which obviously doesn’t work for them too. Can somebody help us with this, pls? Thanks

  • What is a Linux device name for RAID of sas drives?

    - by flashnik
    I have a RAID1 using Promise FastTrack TX2650 consisting of 2 SAS drives. What is a Linux device name for them? Like sda is for first sata drive. I have Windows server so I can't look it directly but need this information for smartctl usage. UPDATE. I found how to access RAID: smartctl -d scsi sdb (because I also have a SATA drive). But in this case I just get an information about just raid controller though I wantto get information about drives itself. Is it possible? Promises's control panel provides information only about their healthy status (boolean) and I want more. Mostly now I need information about temperature.

  • Running scheduled web scripts in a Windows Server environment

    - by Dan Murfitt
    I'm trying to get a scheduled web script running on a Windows Server and so far the only way I've managed to automate this process is by using the Task Scheduler to open Internet Explorer with the web address as a parameter. I then need to create a separate task to run just after this task to close Internet Explorer (otherwise the task doesn't complete). Is there a better way of doing this? I've also managed to run the script by calling the web address through a Telnet connection to the web server (GET /web/address/here) but I haven't found a way of automating this process on a scheduled basis. Any ideas appreciated

  • File open fails initially when trying to open a file located on a win2k8 share but eventually can su

    - by Ruddy Douglass
    Core of the problem: I receive "(0x80070002) The system cannot find the file specified" for roughly 8 to 9 seconds before it can open it successfully. In a nutshell, we have two COM components. Component A calls into Component B and asks for a UNC filename to write to - the filename returned doesn't exist yet, but the path does - it then does its work, creates and populates the file, and tells Component B its done by making another com call. At that point Component B will call MoveFile to rename the file to its "official" name. This code has worked for (literally) years. Its works fine on win2k3. Its works fine when its running on win2k8 and points to a share on a win2k3 server. It also runs fine, if the share is actually located on the same win2k8 machine that the code is running on. But if you run it on win2k8 and point it to a share on a different win2k8 server, it fails. Both Component A & component B exist in their own Windows Service running with as a domain admin account. The shares are configured for "Everyone/Full control" in all test environments, similarly so are the underlying folders that the share points to. All machines are in the same domain. During debugging I realized the file actually does exist by the time I get to checking manually for it - after several iterations it occurred to me that the file doesn't "show up" until some delay passes by - so I put in the loop below in component B as shown below: int nCounter = 0; while (true) { CFileStatus fs; if (CFile::GetStatus(tempname, fs)) break; SleepEx(100, FALSE); nCounter++; } This code does, in fact, exit and nCounter is generally between 80 & 90 iterations when it does -- indicating the file "appears" approx 8 to 9 seconds later. Once that loop exits the code can successfully rename the file and all further processing appears to work. I put a CFile::GetStatus in component A immediately before it calls into Component B and that indicates success - it can see the file and get its true size yet the call into component b made immediately after can not see the file until the above indicated delay passes. I have verified the pathnames are precisely the same, even though it would clearly have to be for the calls to eventually succeed after a pause of 8 to 9 seconds... When something like this occurs I always assume there is a bug in my code until proven otherwise, but given (a) this code has executed properly for a very long time and (other than my diagnostic loop added) has not changed, and (b) it works in all environments except the win2k8 - win2k8 share, I'm guessing there is some OS issue in here that i do not understand. Any insight would be helpful. Thanks!

  • Problems with RDC into Win2008 Server

    - by Jason
    I'm having the same problem with a variety of new machines that I have built. When I RDC into the machine, the display does not update correctly. I get partial images, or refreshes only every 20-30 seconds. It is completely unusable. Eventually, it will even disconnect even though I am logged in. From RDCing into the machine, it looks like the machine is down, but it is fine. I can connect to it with an monitor and the problem is not visible. I think it is a problem with my network configuration. What should I look for to resolve this?
