To work around this problem, do one of the following:

•	Check physical connectivity by pinging the primary domain controller by IP address and name.
•	Check connectivity through NET USE * \\PDCNAME\Share at an MS-DOS command prompt.
•	Review entries in the primary and secondary WINS servers for inaccurate records.
•	Under User Manager for Domains, Policies, Account, click to clear the Users must log on in order to change password check box.
•	RestrictAnonymous has been set to 1 on the PDC, which prevents the user from connecting to the PDC with a Null Session from the client workstation. The user will not be able to change his or her password before he or she logs on to the domain. The user can change his or her password after he or she logs on to the domain because he or she will not be connecting to the PDC with a null session at that time; the user domain credentials will be passed to the PDC while trying to set up the session.
