I tried to get some raw performance counters from remote systems (W2K3, W2K8) with the Refresher. The local system is XP SP2. All settings of the firewalls on the remote systems are MS conform: Connecting to WMI Remotely Starting with Vista http://msdn.microsoft.com/en-us/library/aa822854(VS.85).aspx Connecting Through Windows Firewall http://msdn.microsoft.com/en-us/library/aa389286(VS.85).aspx But the Refresh() call brings 0x800706ba (RPC server not available). The same error comes with Wbemtest, when using the Refresher. I can resolve the problem with the following exception in the firewall: netsh firewall set allowedprogram program=C:\windows\system32\wbem\wmiprvse.exe name=WMIPRVSE mode=ENABLE But this exception is not mentioned from MS. Do I have a security risk with this exception? If yes, what exception do I need for working with Refreshers? Thanks Enno
