RpcProtocol Registry key

This reg key determines which protocols (tcp, named pipe, lpc) by dns server for rpc operations.
The allowable values for the registry key are

1 ---- Tcpip
2 ---- NamePipe
3 ---- LPC

The registry is located at "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters"

DNS server sets up RPC endpoints to allow connections over those protocols mentioned in rpcprotocol.

To set reg key value to 1 run the following command

reg add "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters" /v RpcProtocol /t reg_dword /d 1 /f

if the reg key value set to 0, then dns server can't use rpcprotocol service
