[THIN] ICA listener not reponding after reboot

Hi all,
Wondering if anyone has had this problem on Windows 2003 Citrix servers PS 4.5?

After a daily reboot, no one can connect via ICA.  RDP connections work fine.
The event log has events complaining about the following files:

C:\windows\system32\vdtw30.dll

C:\windows\system32\tsddd.dll

C:\windows\system32\rdpddd.dll

If I reboot it again, it usually starts working again.
This started happening after the latest MS security and .NET patches.

Is anyone experiencing this?
