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. For information on obtaining the service pack, query on the following word in the Microsoft Knowledge Base (without the spaces):
