RPC server unavailable SBS2003 domain

[AndrewFrost]

Hi

We have installed lansweeper on several SBS 2003 networks and all PCs are having the same issue
Wmierror The RPC server is unavailable. (Exception from HRESULT: 0x800706BA) XW4400 (192.168.241.18). The connection tester reports the same.
Have checked DNS, disabled firewall, changed ISA 2006 RFC compliance, run Micrsoft WMIDiag and a few other things we have found in the forums to no avail.

Wondering perhaps if there is an issue specific to SBS2003?

There is no errors listed in errorlog.txt.

Aoplogies for cross-potsing I originally posted this in knowledge base by mistake.

TIA Andrew

I don't have acces to any SBSservers, but I had similar issues and the dcomcnfg.exe security settings solved the problem.
