  • Terminal Services Licensing - Windows 2000

    Hello all,

    I am having a problem with a new 2000 Advance server TS Licensing server, I have activated it with MS on the phone and all seems ok but I when I try to open the TS Licensing manger I get an error about "windows unable to connect to a licensing server" in the eventlog I am getting unable to issue a client license too when a client connects.

    Anyone any ideas what could be the issue?

    Thanks,

    Did you tried to review:

    bdw.. Windows 2000 will be end of life in 2-3 months from now. Please consider to move to Windows 2008 R2.

      Thanks Yuval,

      I have just read those, nothing seems to be pointing to the same problem as mine, I deleted the client key on a xp machine last night and it got a new license even though it says when I try to open the TS license manager it's unable to find one.

      The clients connect ok then say the connect has been ended..and in the eventlog it says the server is unable to issue a license..

      We have a 2008 TS server with on the same w2k domain and that all seems to be working ok with licenses I have read and set it up with the domain prep etc and it is running ok.

      Thanks,
      Kind Regards,
      Simon

        Just an update incase anyone else has the issue.

        It turns out that the license server was dishing out a licenes but would only allow the client to connect once and that was it.

        It wasn't anything to due with the license server though it was an issue with the MTU settings on router as discussed in the below thread.

        http://forums.citrix.com/message.jspa?messageID=471836

        This is what sorted it for me.

        This one had us troubled for a while.

        In our case it was down to a line upgrade, and reconfig of a router between the client and the Citrix box. The router had no specific MTU setting, so must have used a default somewhere in the 1200-1400 range as far we could tell - should have been 1500.

        The easiest way to tell whether it is an MTU problem is to enable blackhole detection on the client PC (WinXP/2000 only as far as I know).

        FYI here's how it's done (as administrator):

        1. Start Registry Editor

        2. Locate the following key in the registry: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\tcpip\parameters

        3. On the Edit menu, click Add Value (Data Type: REG_DWORD), and then add the following registry value: Value Name: EnablePMTUBHDetect

        Set the value to 1

        4. Reboot
        5. Test the connection to the Citrix box.
        If the solves the issue, get your network administrator to check all the routers between the client and the server and make sure they are singing from the same MTU hymn sheet. Or just install the Black Hole detection reg key on all clients - why this doesn't come as default with Windows is mystery.

        Thanks for your help!
