SYMPTOMS
When you log on to a Windows NT computer using cached domain account information, you cannot connect to share points defined on the local computer using your cached credentials.

If you try to connect to a local share using cached credentials, you are prompted for a password. After you type a password, the connection attempt is unsuccessful and you receive a "bad password" or "unknown user name" or error messages. However, you can still connect to local share points using locally defined user accounts.



CAUSE
This problem is a result of the application of the LSA2-FIX security hotfix. The LSA2-FIX is a Windows NT 4.0 post-Service Pack 3 hotfix that is also included in Service Pack 4 and Service Pack 5.

When the LSA2-FIX is applied, connections to share points are allowed only if a domain controller is available to revalidate your cached credentials. This is incorrect behavior. Your cached credentials should be accepted as valid, and the connection attempt should succeed, as long as your domain account has appropriate access rights to the share point.

For more information about the LSA2-FIX security hotfix, please see the following article in the Microsoft Knowledge Base:
