The "RPC service unavailable" solution appears when an additional DC is installed.

After using the Active Directory of Virtual Machine installation for Windows Server 2003 sp 1, we found that "RPC server unavailable" appeared when the system was used to install additional DC ", in this way, "BDC" cannot be installed, and the solution is finally found:

1. Use Net start RPCSS to start the service // usually start 2. Access the master DC Through the UNC path and enter the Administrator and password, the most important thing is this: 3. When entering a domain name, we usually enter the DNS domain name, for example, Microsoft.com. In fact, we should enter the NetBIOS name as the best, you can test the three servers by entering Microsoft to solve the problem. I hope to make a little helping for friends who often encounter RPM errors.
