SYMPTOMS
Computers running the Microsoft TCP/IP dynamic host configuration protocol (DHCP) and Windows Internet Naming Service (WINS) compatible protocols, fail to register domain names when a DEC Pathworks 5.0 server has already registered that name. This problem occurs when the Pathworks server is part of the domain, or if the name is specified with the OTHDOMAINS parameter.



CAUSE
Computers using DHCP and WINS use the NetBIOS over TCP/IP h-node implementation by default. DEC Pathworks servers use b-node implementations. Following the RFC 1001/1002 specs, only 3 node types are standardized, b-node (broadcast), p-node (point-to-point), and m-node (mixed) implementation. The h-node (hybrid) used by Microsoft uses the reserved field and follows the recommendation made in a new, draft RFC.

Traces show that in response to the NetBIOS NAME_QUERY_REQUEST frame sent by the booting computer, the Pathworks server responses correctly, indicating that it has the domain name registered as a group name. The next step performed by the workstation is registering the domain name. The Pathworks server sends a NAME_IN_CONFLICT frame indicating that it has the domain name registered as a unique name. This prevents the booting machine from registering the domain name, and keeps the redirector and server from binding correctly to TCP/IP.

The problem does not to occur using b-node implementations on computers running the Microsoft TCP/IP DHCP and WINS compatible protocol.



RESOLUTION
Contact your local Digital representative to obtain a newer version of Pathworks version 5.0C for OpenVMS, to solve the problem.
