"Connect Network Drive" Caches First Credentials Supplied

When you connect to a remote resource using the Connect As and Reconnect At Logon options within either File Manager or Windows Explorer, Windows NT caches the first set of credentials supplied, even if these credentials are invalid and fail to provide access to the remote resource. Subsequent attempts to access the remote resource with valid credentials will give the user access to the resource, but do not change the cached credentials used when reconnecting.

Be sure to provide the correct set of credentials when filling in the Map Network Drive dialog box.

Microsoft has confirmed this to be a problem in Windows NT version 4.0. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.

Steps to Reproduce the Problem

1. Open Windows Explorer and click Map Network Drive.
2. Specify the standard UNC \\<servername>\<sharename>.
3. Specify a <DomainName>\<UserName> in the Connect As field, misspelling either the DomainName or the UserName.
4. Click the Reconnect At Logon check box.
5. Click OK.
6. You can now correct your mistake from step 3 by typing the properly spelled DomainName or UserName. Also type the password.
7. Click OK. You should now be mapped to a resource.
8. Log off and then log on again.
9. During the logon sequence, you will be prompted to provide credentials to reconnect to the resource. Note that the misspelled DomainName or UserName is displayed, and you cannot change either one. You must click Cancel at this point. Also, you should click the "Do not Try to Restore this Connection in the Future" check box.
