  • AD DS or AD LDS

    - by rajeevrautela
    Hi all, Greeetings !!! I need a suggestion about having AD DS or AD LDS for my infrastructure. So lets begin, Ex. I am having a website which as of now do not have any log in facility for the visitors, now we are developing a new application so that the visitors can create account on the website. the best example you can think of is of any telecom service provider, they have their webiste and now is creating a login facility for it's customers so the users can create an account and can subscribe for ebill sort of facilties. Hope the situation is clear now. for this particular application, i intend to have a web server, an application server, a DB server, one SMTP server and one AD server(for authentication of users and for saving the profiles also). My question here starts on AD front, here do i need AD DS or AD LDS here, what i need from AD is 1) provide user authentication, 2) provide role based access. this is my query. hope i'll get the answer very soon.

  • Windows Server 2003 Terminal Server does not give out all available licenses (solved)

    - by Erwin Blonk
    I installed the Terminal Server role in Windows Server 2003 Standard 64-bits. Still, only 2 connections are allowed. The License Manager says that there are 10 Device CALs available, which is correct, and that none are given out. For good measure I let the server reboot, to no effect. Before this, there was another server (same Windows, except that it is 32 bits) active as a licensing server. I removed the role first and then then added it to the new server. I then removed the Terminal Server Licensing Server component off the old one and added it to the new one. After that, I added to licenses. When that didn't give the required result, I rebooted to new server. Still, the new server, with licenses and all, acts as if it has the 2 license RDP. The server are all stand-alone, there is no active directory been set up. Both servers are in different workgroups. Update (4/12/10): The server has changed the entries in the Terminal Server Licensing a few times. After installing the licenses it added an entry of which the exact phrasing I forgot but it was about temporary Windows 2003 device licenses. Later it added Windows Server 2003 - TS Per Device CAL. The temporary held 2 licenses (standard RDP licenses, I think) and the other 10. At some point, seemingly unrelated from the testing we did, it used a licenses from the new pool. This morning, 2 licenses were used from the pool of 10 and only 1 from the temporary/RDP pool (I wish I had screenshots to show, it changed every few hours oir so it seems). Although I had already activated the server over the internet, and re-activated it, I decided to go through the whole procedure by phone. Update 2 (4/12/10) The problem has been solved. It seems the activation over the web, while it said to have succeeded, did not work correctly. After activating by phone, it did work. What was different from the old setup and what put me on the wrong foot from that moment, was that I now need to create seperate user account because a session with one user account will be taken over by someone else when that account is used by that person. On the previous server, it was possible to open several sesions with the same account. We now use Per Device licenses, I'm not sure what was used before. Thanks all for the replies.

  • How to migrate from Natara DayNotez for Pocket PC / Windows Mobile

    - by piggymouse
    I've been using DayNotez as my notes manager since the old Palm PDA days. When I moved to Windows Mobile, I installed DayNotez there and migrated from the Palm version. Now I wish to move from DayNotez altogether (I currently consider Evernote as a decent cross-platform tool). Problem is, DayNotez doesn't let me export the notes (unless I want to transfer them one by one, which is a pain). Natara offers an export tool for Windows, but it only works for Palm HotSync (as it reads from the backed-up PDB file). DayNotez Desktop for Windows stores its local DB under "My Documents\Natara\DayNotez\" directory in a file named "[device name] DayNotez.dnz". Quick look within the file spots a string "Standard Jet DB" near the beginning, but I couldn't open it as a regular JET/MDB file. Any help would be greatly appreciated.

  • Get-ADGroupMember returns nothing while being completed successfully

    - by Volodymyr
    I've tried to list all of the members of one of the groups in AD, but nothing is returned, although the command is completed successfully. It neither works with group DN specified, instead of sAMAccountName. Get-ADGroupMember "sAMAccountName" -Recursive | select name See output below: The following message appears if one views Members from dsa.msc --------------------------- Active Directory Domain Services --------------------------- Some of the object names cannot be shown in their user-friendly form. This can happen if the object is from an external domain and that domain is not available to translate the object's name. --------------------------- OK --------------------------- Can this be a reason for powershell not returning results? Any thoughts? UPD: this doesn't seem to be permissions issue, since dsquery does return group members.

  • FreeBSD performance tuning. Sysctls, loader.conf, kernel.

    - by SaveTheRbtz
    I wanted to share knowledge of tuning FreeBSD via sysctls, so i'm posting them with comments. Based on Igor Sysoev (author of nginx) presentation about FreeBSD tuning up to 100,000-200,000 active connections. Sysctls are for 7.x FreeBSD. Since 7.2 amd64 some of them are tuned well by default.

Don't forget to specify server type (web, smb, gateway, etc) Let's share experience!

  • VMware Workstation Error: Cannot find a valid peer process

    - by Robert Claypool
    I am running VMware Workstation 6.1.5 (build-126130) on CentOS 5.3 (Final). One of the guest machines is reporting an error when I try to power on the most recent snapshot. Snapshots further back in the timeline will power on without any problem. Error: Unable to change virtual machine power state: Cannot find a valid peer process to connect to. Apparently I'm not the only one with this problem. Others have been reporting it since at least early 2005. The forums say to delete unused lock files and restart any hung VMware processes (or restart the host machine), which I have done. Still no luck. Any other ideas?

  • How to normalize a word document?

    - by AngryHacker
    I was too cheap to hire someone to retype a really, really long scanned document full of legalese. So I OCRed it using OmniPage. But the OCR output was kind of disappointing. I got a word doc that has multiple line spacings. The before and after paragraph heights are different all over the place. This would be easy, if the entire document had the same paragraph settings, but it does not. There are probably a half dozen different styles going on. What is the easiest way to normalize the document? For instance, if one paragraph has a line spacing of 20.4 pt and another one has a spacing of 20.9 pt, then I'd like to consider them the same style and set them to a single value? Or really, any suggestion is welcome at this point.

  • Hardware firewall vs VMWare firewall appliance

    - by Luke
    We have a debate in our office going on whether it's necessary to get a hardware firewall or set up a virtual one on our VMWare cluster. Our environment consists of 3 server nodes (16 cores w/ 64 GB RAM each) over 2x 1 GB switches w/ an iSCSI shared storage array. Assuming that we would be dedicating resources to the VMWare appliances, would we have any benefit of choosing a hardware firewall over a virtual one? If we choose to use a hardware firewall, how would a dedicated server firewall w/ something like ClearOS compare to a Cisco firewall?

  • Terminal Services printing

    - by Adam
    Hi We are using a hosted terminal server to run some applications on. We have three users who connect to the server through RDP and try to print to a networked printer called: HP Photosmart C7280. One of the users is using Windows XP Pro 32-bit on the host and when they print through the terminal server it works fine. Another one of the users is using Vista 32-bit on the host and when they print through the terminal server it works fine. The third user is using Windows 7 64-bit on the host and when they print through the terminal server it only print the first line of the page (A test page print 3/4s of the test page compared to printing all of the page when using the other 2 machines). We are only printing from Word 2007 and Excel 2007 on all machines. The server is Windows 2003. No errors in the event log. Any ideas?

  • FTP corrupting subsequent aiff files from old mac to new mac

    - by eighteyes
    This is a bizarre one. So I am trying to xfer files from an old mac to a new mac, but the old one has no USB, no firewire, just ethernet. So I hooked it up the the network, downloaded fetch and started a FTP server. The first file transfers fine, but all the subsequent ones are corrupted. I can reconnect and transfer a new file and it works, but every file afterwards is corrupted, somehow. I tried forcing binary transfer, but that didn't help. Any ideas? From System 8.6 Osx 10.7.5

  • dual boot xp/xp, now win7/xp getting no xp

    - by ped
    I have a laptop on which I have two drives with separate XP installs, one barebones for music production, the other "normal" XP with Office etc. (Unfortunately the bios won't give a boot disk choice) Normally I would be presented with two WinXPs on booting. Selecting the second one would get me into the "normal installation on disk 1 (C).Selecting the first in boot order would give me D: (disk 2) withe barebones XP. However, I installed Windows 7 Home onto disk 1 (C:), but there were no dual boot options anymore, even though I installed DualBoot Pro and added WinXP disk D:. The options now show show up, but seletcing Win XP just turns into a reboot back to where I started. Any help would be much appreciated

  • How to install Windows 7 onto software RAID-0

    - by Jay B
    I recently got a new laptop (Asus G73JH-A2) which has two identical hard drives in it. Unfortunately the motherboard does not have a RAID controller. What I would like to do is run the drives in a RAID-0 configuration to improve performance (plus get the extra capacity on one partition). I would like Windows installed onto the striped volume (RAID 0). I have spent some time using diskpart to create a striped volume across the two drives, however when I go to install windows and select the volume it will not let me select 'Next' giving the error "Windows cannot be installed to this hard disk space. The partition contains one or more dynamic volumes that are not supported for installation." I'm hoping theres a step that I am missing that will allow me to install windows on a striped volume. Any ideas?

  • How does a hard drive compare to Flash memory working as a hard drive in terms of speed?

    - by Jian Lin
    Some experiment I did with hard drive read/write speed was 10MB/s write and 40MB/s read, and with a USB Flash drive, it can be 5MB/s write and 10MB/s read. Also, if I put a virtual hard drive .vhd file in a hard drive or in a USB Flash drive and try a Virtual Machine using it, the one using the hard drive is quite fast, while the one using the USB Flash drive is close to not usable. So I wonder some early netbooks use 4GB or 8GB flash memory as the hard drive, and even the Apple Mac Air has an option of using flash memory instead of a hard drive. But in those situation, will the speed be slower than using a hard drive, like in the case of a USB Flash drive?

  • Samba4 advice for production use

    - by pgb
    I have an old Samba 3 + LDAP server installed that needs to be rebuilt. I'm weighting my options, and Windows Server seems too expensive at the moment, and Samba 4 appeared to be a nice option, coupled with the last Bind 9 that can dynamically add the computers to the DNS. I have about 30 workstations, so I still consider it a small network. My questions are: Is Samba 4 stable enough for production? It seems as if the Samba team is too cautious on when to call their version final, or even beta, as compared with other open source projects. What Linux distribution would you recommend to set it up? I usually use Ubuntu Server, but may use another one if installing / maintaining Samba 4 is better on that one.

    I have an account with on Yahoo! Mail, another on Gmail. In Outlook 2007, I've set them up so that I can access them without having to go to their websites. I've password protected my personal folder, but can't find a way to merge my accounts into one personal folder. When I want to switch between my accounts, I must type my password again. Besides that, I can't check for new mail messages in both accounts at the same time. How do I merge multiple email accounts into one single personal folder on Outlook 2007?

  • SQL Error: -443, SQLState: 38111 when accessing table metadata on DB2 zOS

    - by snowflake
    Hello, I'm getting following error when using Hibernate in a Java application over my DB2 database. This error occurs with one DB2 database and not with another (I'm almost sure the problem is in DB2 server side configuration), and I didn't found the difference between the two databases. The SQL error -443 is missing from the documentation I found: http:// rikipedia.co.za/index.php/DB2_SQL_Error_Codes (one link maximum per question due to reputation) According to following link, the 111 part of the sql state 38111 would indicate the reason of the failure. http://www.sqlerror.de/db2_sql_error_-443_sqlstate_42724.html Any idea ?

  • 8Gb Fiber Channcel HBA vs. 10 Gb SPF+ Converged HBA

    - by Hossein Aarabi
    I am putting a Dell server together, more specifically R720. I have to select the correct Host Bus Adapter. This HBA on R710 will connect to a storage device. I am confused between these two: QLogic 2562, Dual Port 8Gb Optical Fiber Channel HBA (price $2,045) QLogic 8262, Dual Port 10Gb SFP+, Converged Network Adapter (price $1,618) I thought since the QLogic 2562 is a fiber channel and is more expensive then it is faster in terms of IOPS. But, it is a 8Gb as opposed to 10 Gb of SFP+. My questions: Which one is better (IOPS performance, etc.)? Why should I choose one over another?

  • Why does my ReadyNas 4200 have a constant beep post disk failure

    - by swagner88
    Went to check on a high pitched constant beep coming from the server room and discovered that all the LED lights on the disks were black except one which had a constant green. Post a Re-boot nothing changed. Console indicated that that particular drive has failed. Pulled the drive out and BAM everything is fine. Except, the high pitched beep remains. Plan is currently to replace the drive with a new same size drive we happen to have purchased for expansion. My question is, what will this do? Will the NAS accept the new drive as a replacement for the failed one and decide to shut-up? The Manual for the device is almost to straight forward and says that I can just swap drives out as I need but I find that difficult to believe: http://www.readynas.com/download/documentation/HM/RN4200_HW_24May10.pdf

  • asterisk/freeswitch in nat/no-nat setup

    - by pQd
    hi, my current setup - i use bunch of sip hard-phones around few offices. all devices have two sip accounts configured - one on internal sip proxy [for calls between the branches], another - at 3rd party voip providers [ since it's in different countries - those are different providers, but that's irrelevant ]. i was thinking about terminating sip calls on something like asterisk/freeswitch server and having all sip-devices log on just once to such server[s] - mostly to provide things like voicemail, groupcalls, redirections etc. it seems perfectly doable but there is one problem - i cannot find examples how to prepare for nat/no nat. for calls routed to from/to 3rd party voip operator - i'll need handling for nat/stun etc, but for handling of internal calls - i do not want any nat, all traffic should go via vpns to different branches. can you provide me some hints how to configure it? any tutorials? thanks!

  • SysAdmin Career Question: Internal or Client Based

    - by Malnizzle
    ServerFault Community, It seems there are two positions SysAdmins find themselves in, either you are working for a non-IT services based single client (your employer) and providing in-house IT support or you work for a company who provides out sourced IT services to multiple clients. Right now I work for a company who does the latter, and I often consider how nice it would be doing the in-house side of things, to just have one network I am focused on and instead of feeling like I have a dozen bosses between clients and internal management, I would just have one set of management and people to appease. There is also the technical aspect of every client wanting something different, and having to manage numerous different technology platforms, or trying to force clients into using the technologies we prefer, neither situation is enjoyable. Is this just "the grass is greener on the other side" syndrome, or is there some legitimacy to the the stress of client based IT work compared to being an in-house IT guy? Thanks!

  • How to connect two monitors to a macbook pro?

    - by CIRK
    I have a 13" macbook pro, and I need much more space right now, so I decided to buy two smaller monitors. (these from LG). But I don't really know how will I connect them. I've seen some products like this Diamond BVU195, but it's not currently in stores in my country. I've found these Equip 128450 USB 2.0 Display Adapter DELOCK USB 2.0 to DVI/VGA/HDMI Adapter The second one looks pretty cool, but it says that Windows is a system requirement or what, so I'm not sure if it will work with mac os x? So how did you connected multiple monitors to you mac, and are these adapters the best choices, if yes then is there an OS independent one?

  • Re-Calibrate Toshiba battery meter with Windows 7

    - by Mark Henderson
    I have a Toshiba U300 laptop. Back in the olden days (circa-2000) you could re-calibrate the battery meter from the BIOS when your battery was no longer reading accurately. My battery was shot, so I bought a brand new one, however Windows 7 still seems to count down the battery life in at the same speed as the old one did. This time, when it alleged 0%, I turned the laptop back on and got another 90 minutes of life out of it, at 0%. Is there a tool or utility for Toshiba laptops that can fix it back to being accurate? I've read the other threads on SU about cycling the battery but that just doesn't seem to do it in this case. Update: After the last cycle, the battery meter now reads 100% but the indicator on the front of the laptop is still orange (indicating not fully charged)
