We are running Windows Server 2003 SP1. Clients are either Windows XP SP2 or Windows 2000 SP4. I have two accounts that have domain admin rights. When I'm logged in to any server using either of the domain admin accounts I am unable to perform a network logon to any of the client computers. Specifically, when I go to run->\\<computername>\admin$ I get an error that says, " The account is not authorized to log in from this station". When I try to map(i.e. cmd-> net use * \\<comptuername>\admin$) I get system error 1240 - The account is not authorized to log in from this station. However, when I perform the same function but on one of the client computers using the same domain admin accounts it works. I've been through the group policies and didn't see anything out of the ordinary but then again I'm not a group policy expert. I'm hoping someone here can point me in the right direction. Thanks in advance.
