Access denied error for WMI query




My PRTG server is part of an AD domain and i have problems with WMI for workgroup servers that are not part of this domain. No problem with the servers within the domain. I have tried using the WMI test tool and i got the error "8007005:Acess is denied error". i'm using the local administrator account for the credentials.

With the help of the knowloedge based, i have verified that port 135 is open, “ForceGuest” is set to “0” and windows firewall is disabled. Furthermore, i have added the admin account to the DCOM user group and the Performance Monitoring Group. Under the DCOMCNFG, i have check that the DCOM user group has remote launch and remote activtion set to "Allow".

The weird thing is that i can run the query successfully if i execute the tester locally from the client server itself but got the error when launching the tool remotely from another server

kindly help

Thanks Thomas

Please try using "localhost" as domain name - does that help?

Kind regards,
