SYMPTOMS
When you attempt to dial out using the Remote Access Service (RAS), you may receive the following error message:

RAS Error 633: The port is in use or not configured for Remote Access Dial-Out.

Stopping and restarting the Remote Access Service temporarily resolves the problem.



CAUSE
If Rasdial.exe terminates prematurely, it can leave the port in an indeterminate state. The port disappears from Remote Access Server Manager if it is configured for dial-in.

This problem is not specific to Rasdial.exe. Any program that terminates prematurely without clearing the port state may cause the same problem.



RESOLUTION
Install the latest Service Pack for Windows NT version 4.0.



STATUS
Microsoft has confirmed this to be a problem in Windows NT version 4.0. This problem has been corrected in the latest U.S. Service Pack for Windows NT version 4.0. For information about obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base:
