SYMPTOMS
A Remote Access Service (RAS) client dials in to a RAS server using NetBEUI as the protocol. If the RAS server is configured to allow access to the remote network, RPC applications initiated at the RAS server cannot connect back to the RAS client. The RAS server may hang up the line, and log Event 20014.

One such application is the Microsoft Exchange Dynamic RAS Connector.



CAUSE
When a network application is run on a RAS server, and it tries to connect to a RAS client, if access to the entire network is enabled, then the network traffic is processed by the RAS NetBIOS gateway. RPC applications have a problem interacting with the RAS NetBIOS gateway over NetBIOS/NetBEUI.



STATUS
Microsoft has confirmed this to be a problem in Windows NT version 4.00 This problem was corrected in the latest Microsoft Windows NT 4.0 U.S. Service Pack. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

MORE INFORMATION
NOTE: In order to have the RAS server NetBIOS gateway proxy for client NetBIOS application names, such as those registered by the Microsoft Exchange Server MTA (Mail Transfer Agent), you must set the following registry parameter to 2.

Value Type: REG_DWORD

Default: 1 (change to 2)
