Hi Tom Howarth I'm experiencing your issue right now and I've just realized that I had a LOOP in my login script. You are probably experiencing the same issue as me. The component stuisrv.exe is used to run the Microsoft Login Script from the group policies... look at your script by making it running visible... you should see where the loop is. this is a recent occurrence and no new applications have been loaded and there have been no configuration changes. The MetaFrame logon progress form is sticking at "Running Logon Scripts". Now I am not running any scripts other than usrlogon.cmd and that is fine. If I run a published desktop the desktop appears (the logon progress form behaviour is the same)and I find the application that is causing the issue is STUISRV.EXE. I can find no information on this app but it is a Citrix application and is found in program files\citrix\system32. My users can work in a full desktop environment but this is not acceptable. If I rename the application the or stop it with Task manager the desktop carries on running but a published application will still not load. This behaviour also occurs if I create a new Published application. I am running win 2k3 with PS3. __________________________________________________________ Marc-André Lapierre Consultant Systems & Infrastructures 514 977-6170 Email : <mailto:malapierre@xxxxxxxxxxxxxxxx> malapierre@xxxxxxxxxxxxxxxx
