Andrew, Just a thought, but when you attempt to login are you using the fully-qualified username in the form "domainname\username"? Tom Thomas P.

I read and tried the articles about changing windows 98 to accept NTLN v2. That did not work. I also tried to use the AD client for windows 98 and that failed. It said my password was invalid on the domain. Thanks Andrew McCormack
