TITLE

IBM OS/2 LAN Requester Cannot Logon to a Microsoft Windows NT Server on a Different Subnet

DESCRIPTION

You are unable to net use or logon from an IBM OS/2 LAN Requester to an NT Server on a different subnet using TCPBEUI.

IBM OS/2 LAN Servers and LAN Requesters (using TCPBEUI with P- and H- node and WINS capability) register their domain names in the WINS database with a 0x'00' termination, whereas NT and WIN95 register their domain names with 0x'1C' termination.

Only the 0x'1C' terminated names will be added to the Internet group, making them accessible across routers. The result is that no IBM OS/2 LAN Requesters from a different IP subnet can ever logon to an NT domain using TCPBEUI.

RESOLUTION

Add the following line to the MPTN\ETC\HOSTS file on the IBM OS/2 LAN Requester:

5.5.55.555 DOMAINNAME NETBIOSNAME

where:

5.5.55.555 is the IP address of the NT server
DOMAINNAME is the domain name of the NT server
NETBIOSNAME is the NetBIOS name of the NT server

Note: The HOSTS file can be created or modified by using the
TCP/IP Configuration Notebook; go to the HOSTNAMES tab, then
move to Page 2, Configure Name Resolution Services.
