SYMPTOMS
When you use a Simple Network Management Protocol (SNMP) program to read performance-related data from the Microsoft Internet Security and Acceleration (ISA) Server 2000 extension DLL files, you are unsuccessful. If you run the Snmputil.exe program to step through (walk) each ISA Server namespace, you receive a result that is similar to the following:
** bwcmib.dll **
MIB definition:
- OID: .15 .1
- NS: .bandwidthControl.bwcStatistics
SNMP Sample Response: SnmpExtensionInit() failed.
"snmputil walk" Response: End of MIB subtree.
The ISA Server SNMP components do not respond correctly. Either the namespace is not correctly resolved, or the DLL returns an "End of MIB" result.
