'Error 5: Access Denied' When Connecting Using PPTP (242349)
The information in this article applies to:
- Microsoft Windows NT Server 4.0
- Microsoft Windows NT Server 4.0 SP5
This article was previously published under Q242349 SYMPTOMS
When you attempt to make a PPTP connection from a client computer running Windows NT 4.0 Service Pack 5 to a server running Windows NT 4.0 Service Pack 5 that is running Routing and Remote Access Service (RRAS), the initial authentication attempt may not work and you may receive the following error message:
Error 5: Access Denied
This problem can also occur if (RRAS) is configured to forward MSCHAP v2 authentication requests to a Non-Microsoft Remote Authentication Dial-In User Service (RADIUS) server.
CAUSE
This problem occurs because there is a problem with negotiating MS Chap V2 with NON Microsoft Radius servers. We have enabled a registry setting to negotiate MS chap V1.
