— End of inner exception stack trace —at DTEAutomation.Class1.Main(String[] args) in c:\vs7play\enterprisetemplate\dteautomation\class1.cs:line 80

Resolution
You may experience the behavior when the user account that you use to run the program does not have the Impersonate a client after authentication user right(the SeImpersonatePrivilege function). When you upgrade Windows 2000 Server Domain Controller to SP4, the user account (IWAM) is not grantedSeImpersonatePrivilege, and then programs that use impersonation may not work correctly.
