Windows NT Operating System SNMP OID Incorrect (154784)

The information in this article applies to:

Microsoft Windows NT Workstation 3.51
Microsoft Windows NT Server 3.51

This article was previously published under Q154784

SYMPTOMS

SNMP traps generated on Windows NT Workstation and Server provide an object ID (OID). Where you expect to find the OID designating the Microsoft operating system, Inetmib1 sets as EnterpriseOID in the SNMP trap packet the following string:

   1.3.6.1.2.1.11

Also the OID length is set to a greater value than the actual length, and three more unnecessary values are always attached to the OID.

CAUSE

Inetmib1 sets the incorrect value for EnterpriseOID and an incorrect length for the OID.

MORE INFORMATION

When the update below is applied to the Windows NT computer, the following IDs can be used to identify the type of Windows NT computer via SNMP:

   3.1.1 for workstation
   3.1.2 for servers
   3.1.3 domain controllers (DCs)

STATUS

Microsoft has confirmed this to be a problem in Windows NT version 3.51 and 4.0. This problem was corrected in the latest Windows NT 3.51 U.S. Service Pack and in the latest Windows NT 4.0 U.S. Service Pack.
