Connecting to a Local Share Using Cached Credentials Is Unsuccessful in Windows NT 4.0 SP4 and SP5

ID: Q231934


The information in this article applies to:
  • Microsoft Windows NT Workstation versions 4.0 SP4, 4.0 SP5
  • Microsoft Windows NT Server versions 4.0 SP4, 4.0 SP5
  • Microsoft Windows NT Server, Enterprise Edition versions 4.0 SP4, 4.0 SP5


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:

WORKAROUND

To work around this problem, connect to local share points using a locally defined user account after you log on with cached domain account credentials. For example, type the following command:

net use \\computername\sharename /user:computername\username password


STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem was first corrected in Windows NT 4.0 Service Pack 6.
