_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*.
