I shadowed the user and the issue is persistent, TRIM given an impression that it is loading, but fails to load, leaving trim.exe running in the taskmanager, with no TRIM client interface appears to be there.
However when I log on the same server, it works fine, with no issues.
No, if this was a window position, it would have been present on the the Applications tab of Task Manager and also on the task bar. It's not there on Task bar and nor in the applications tab of the task manager.
There is a flash just before the TRIM client disappears and TRIM Client is no-where except for TRIM.exe in the Processes wihich I can't delete due to Securirty restrictions.
What causes the dis-appearence of the TRIM client is certainly a mystery, I tried loading it from the location where TRIM.exe resides, shortcuts, other program menus...but all scenarios ..leave an impression that it is loading and then disappears.
Only one such user as opposed to all others working fine with this user having identical Permissions to others as permisssions based on the group domain and they are identical.
