This article was previously published under Q194465 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.
