I can't see mail queue length on a Ex2K3 server, but no problem with another Ex2K3 server. These 2 servers are under same domain but different location (& different VLAN). I have run below wbemtest command and get invalid class error - no more detail.
1. On command line execute wbemtest
2. Connect to the Exchange Server (\\EXCHANGE_SERVER\root\default) and specify the credentials you are using in Exchange Monitor
3. Try running the following query
SELECT LocalQueueLength from Win32_PerfRawData_SMTPSVC_SMTPServer
Pls advise how to fix this issue.
Thanks and regards,
