Help with configuration of windows test

Hi All,

we have in our organization nagios 2.5 running on production. all windows test are performed with the hlep of a web-service (no agents used) connecting to the wmi of the windoes servers.

I am trying to set-up a test environment,
Unix server is up and running, i created a web-service on the windows test server (and configured the viryual directory on it) and started nagios.

The problem (i think) - all the windoes test that should use the web-service fail and i get the next message - "COM object that has been separated from its underlying RCW can not be used. "
all other test are running and reply well.
what is the problem?

Thanks in advance,
Gilad
