  • TS Slow Logons and unexpected disconnections

    Any good advice?
    new build Server - Win2003R2, fully SPed and patched
    System is Quad Xeon 2.8, 4GB RAM, RAID 5
    4GB Page file on different partition to the OS
    Local profiles, not roaming
    Main user requirement is custom Access 2003 application and Outlook 2003, but will be adding SAGE later
    Currently running TS in evaluation mode because I need to move the licensing server

    Users are complaining of slow logons (several mins) and random disconnections
    This is via ADSL or LAN connection


    Any suggestions where I should start on improving server performance?

    Is the DC the server is authenticating agains in the same site? How many GPO's are being applied to the server / users when the log on?

    Normally TS are locked down quite a bit thus more GPO's for the server to process during logons. Do you have the UPHC service running as well? Perhaps the profiles are not unloading correctly when the user logs out thus causing issues when logging back in.

    Just some suggestions.

      1. Try to access the TS from LAN.
      2. Missing license server or the license server reside on remote location (with low bandwidth) can lead this issue.
      3. MTU issue/upload issue.

        Thanks, guys....

        Michael:
        Not much locking down as it is early in setup
        DC is on same site -- 1 Gb LAN
        WTF is UPHC ?? I thought it was a new type of double glazing
        Profiles look good and no issues with logging off

        Yuval:
        Same issues on LAN and remote (note remote is over different port -- 3391 not 3389
        No licensing server as it is in evaluation mode at present
        Can you clarify your point 3?

        Thanks again!

          Sorry Tom, should have really explained about it.

          http://www.microsoft.com/downloads/d...displaylang=en

          Overview
          The User Profile Hive Cleanup service helps to ensure user sessions are completely terminated when a user logs off. System processes and applications occasionally maintain connections to registry keys in the user profile after a user logs off. In those cases the user session is prevented from completely ending. This can result in problems when using Roaming User Profiles in a server environment or when using locked profiles as implemented through the Shared Computer Toolkit for Windows XP.

          On Windows 2000 you can benefit from this service if the application event log shows event id 1000 where the message text indicates that the profile is not unloading and that the error is "Access is denied". On Windows XP and Windows Server 2003 either event ids 1517 and 1524 indicate the same profile unload problem.

          To accomplish this the service monitors for logged off users that still have registry hives loaded. When that happens the service determines which application have handles opened to the hives and releases them. It logs the application name and what registry keys were left open. After this the system finishes unloading the profile.

            Oss,

            This may seem silly but have you double-checked DNS to make sure the entries are correct? I assume you have considering how long you have been around here.

            I did something like this by mistake recently. I accidentally put public DNS as the primary on the internal side. Everything 'eventually' worked but it took a week for the customer to call me and complain. It took me 2 minutes to diagnose and fix my own mistake.

            Good Luck!

              1. Setup and activate a license TS server.
              2. MTU - TCP (RDP) is sensitive to MTU frame size.

              This can lead to some strange issues like what you described.
