SYMPTOMS
Your Windows NT Server computer running the Point to Point Tunneling Protocol (PPTP) may encounter periods where all new client connections will be refused. These periods only last three to five seconds but can happen even when there are Virtual Private Network (VPN) adapters still available.
CAUSE
This problem only happens when clients are dialing in using NetBEUI. The clean up period after a VPN bound to NetBEUI can last three to five seconds. During this period, the VPN will refuse any connections. When the VPN refuses the connection, the server then thinks that all the connections are being used and refuses the entire connection instead of passing the connection on to another VPN.
RESOLUTION
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:
