Você pode tentar as seguintes linhas de comando para adicionar regras de entrada ao firewall no servidor da Web:
netsh advfirewall firewall add rule name="Remote IIS inetinfo" dir=in action=allow description="Remote IIS Service Managment" program="%systemroot%\System32\inetsrv\inetinfo.exe" enable=yes
netsh advfirewall firewall add rule name="COM+ Remote Administration (All Programs)" dir=in action=allow description="" program="%windir%\system32\dllhost.exe" enable=yes localport=RPC protocol=tcp
Eu tive que usá-los para resolver problemas de WMI / RPC ao tentar acessar os serviços do IIS. Erros como:
Creating an instance of the COM component with CLSID {2B72133B-3F5B-4602-8952-803546CE3344} from the IClassFactory failed due to the following error: 800706ba.
