When using Remote Access Service (RAS) with third-party dial-in servers using Shiva Password Authentication Protocol (SPAP), a user account may be locked out if a wrong password is entered. This problem will only occur if account lockout is enabled.
This problem occurs if Windows NT has to retry the authentication request. Windows NT loses synchronization with the server. This causes Windows NT to retry the authentication requests until retries are exhausted.
To resolve this problem, obtain the latest service pack for Windows NT 4.0 or Windows NT Server 4.0, Terminal Server Edition. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:
