I have the same problem.
Fresh install of FMS 3.0 Final on Ubuntu 9.10 Server.
Agent without any configuration in the client side.
The tentacle server is running.
I make the test in a XP pro sp3 32bits in the domain and ina W2K3 SP2 server 32bits.
I get this error in the log when start o restart the agent service:
2010-03-17 11:58:30 Pandora agent stopped
2010-03-17 11:58:32 Pandora agent started
2010-03-17 11:58:33 ReadEventLog error 997
2010-03-17 11:58:33 ReadEventLog error 997
An update:
in my case the WMI Server is set to 0, when i put to 1 and restart server works OK.
But the error continues appearing:
