Dear,

My NT 4.0 PDC server has the following problems, I wish anyone who knows the solution, please give me a hand. Thanks in advanced.

Whenever I browse my PDC printer folder (wanna add printer), it will say "Unable to list printers on \\PDC, Error=1722. The RPC server is unavaible". Same problem when I use RPING to the PDC, which is the Exchange Server installed, it prompts "RPC call raised exception 0x6ba. The server is unavaible.".

Finally, the RPC Service is running on my PDC and all others service are working correctly.
