Unable to browse NT server in AD 2003

Hi,

My company AD 2003 environment is:

2 DC

1 NT server with Exchange 5.5 and print server

I suddenly have this problem:


I created new user account (TestA). I used TestA to login windows and try to
browse the NT server for installing printer driver. However, system prompts a
login window for requesting login. I try to enter TestA’s username &
password, but fail. If I enter the other existing account’s username &
password, it is OK. Then, I restart this NT server, and try to use TestA to
login windows. And then browse NT server again, it is OK now. However, I try
to create new user account (TestB) and do the same action. System will prompt
the login windows again. I try to create account in NT server, but same
result.


I have not changed any configuration and no such problem before.



Any Idea?

Thanks
Ray
