CAUSE ===== This behavior can occur when the SNMP service tries to load the W3pmib.dll dynamic-link library (DLL), but cannot because the World Wide Web service (W3svc) has not yet started. The W3pmib.dll DLL requires the World Wide Web service (W3svc) to be running. RESOLUTION ========== WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk. To resolve this issue, add the World Wide Web service (W3svc) to the Depend On Service list for SNMP: 1. Use Registry Editor (Regedt32.exe, not Regedit.exe) to open the following key: HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\SNMP 2. Double-click Depend on Service. 3. Press ENTER to move to the next line (make sure that nothing is selected). 4. Type "W3SVC" (without the quotation marks). Do not press ENTER. 5. Click OK. 6. Restart the computer.
