I run Windows 2003 Server with automatic logon. It seems to me that some 
services are started after the logon. I base this on noting that I get 
the Some Services Did Not Start alert many seconds after my desktop has 
appeared.

Could the client repeatedly try connecting with some reasonable delay 
between connection attempts?
