Userinit issue - user logs into TS and gets blank screen. User shows in TS manager as logged in, however, the userinit process holds at 13% usage and rarely releases. I can run taskmgr and force Explorer to start, but userinit is still processing. The problem occurs with established profiles and new profiles. In some cases, if we wait 5 - 15 minutes, it will finally load and the problem seemingly goes away. I did install UPHClean and that helped tremendously - prior to that the problem (which suddenly occurred after 8 months of this box running) was more global, maxing the CPU, causing the system to practically halt, and preventing other users from logging in. Since the problem still occurs intermittently, I really need to locate the cause and find a resolution. Thoughts?
More Info - Running on Win2003R2SP2. Once UPHClean service installed, no further errors in Event Log. Currently running UserEnv debug logging to compare faltering logins with successful logins. Hangs after intiating the userinit process - line reads: USERENV(2fe4.664) 19:21:08:909
