I am trying to run some WMI queries on a clients computer running XP SP3 over a VPN. The client is running an SBS2003 Domain which I have a Domain Admin account and full control of. While trying to run queries is get an Access Denied error. I know I am using the right credentials because the same command ran against the server returns the appropriate response.
I have already googled this and spend many of hours troubleshooting. Below is a list of things that I have done.
I have modified the SBS Firewall GPO to allow remote administration (no i can run the query from the server)
I have Added my local subnet as well as * to the allowed list under the above selection.
I have granted the user the appropriate permissions within WMI
I have messed with the DCOM settings VIA a GPO
We do have another vpn to another client running XP SP2 and the queries work just fine. Same devices.
