We use a number of Windows 2000 SP4 + updates and Windows 2003 R2 SP1 servers. We monitor their resources using SolarWinds Orion Network Performance Monitor v8.5.1.0 and SNMP, and it works great.
We've hit a new snag. We've put 500GB Seagate external USB drives on each to act as local backup drives and now the Windows 2000 servers have multiple Event ID 51 'disk' errors in system event log (approx every 15mins).
Actual error: An error was detected on device \Device\Harddisk1\DR3 during a paging operation.
It is not a drive error as all Windows 2000 servers have the same symptom. The Windows 2003 R2 servers don't have the problem. (Sorry, upgrading all servers to Windows 2003 is not a 'fix' option for us).
We've traced it to Orion polling the machines (via SNMPv2c). The USB drive is not selected as a resource to monitor (only the local C: and 
partitions are monitored). In Orion, we 'unmanaged' a test server (but left the SNMP client service running) and the errors stopped. We started 'managing' it again and the errors reappear. I'm not sure if it can or how to run SNMPv3 on Windows 2000 if this may solve the problem.
Does anyone have any ideas on how to stop these event log errors occuring.
Thanks
