What AV software are you using Webster From: thin-bounce@xxxxxxxxxxxxx [mailto:thin-bounce@xxxxxxxxxxxxx] On Behalf Of Minero, Hector B CIV NSWCDD, K55 Subject: [THIN] TermService errors on VMWare Citrix Servers Hi all, once in a while I get the following errors on our VM Citrix PS servers. When we do, no one can log in to those servers. Usually, a reboot fixes them. I was wondering if anyone else has seen these messages and how to fix them. The servers are Windows 2003 Server SP2, PS 4.0 Hotfix Rollup 4 Cannot load illegal module: C:\WINDOWS\system32\vdtw30.DLL. Or Terminal Server session creation failed. The relevant status code was 0xC00A0016. Followed by: Cannot load illegal module: C:\WINDOWS\system32\Drivers\wdica.SYS.
