Clean install of vista enterprise. I can rdp in and use everything like
normal, a few minutes after I disconnect or logoff the event log logs under
Aplication, Event ID: 6003 Source: Winlogon and says:

The winlogon notification subscriber TrustedInstaller was unavailable to
handle a critical notification event.

And I also get under System:

Event ID 1103 Source: Dhcp-Client

Your computer was successfully assigned an address from the network, and it
can now connect to other computers.

The machine is on a domain, no other messages like either of these appear
except under these circumstances, the DHCP one on reboot of course. If I try
to login right after I disconnect it works fine, it seems to only happen
after a few minutes. I get the DHCP message twice and it's always prefaced by
a GroupPolicy error of Event ID: 1058. I have no group policy issues under
normal circumstances however. Group Policy has no rdp or session settings so
I don't believe it to be the problem. Any thoughts would be greatly
appreciated.
