'The RPC Server is unavailable' message on Vista with UAC

'The RPC Server is unavailable' message on Vista with UAC

In this post, I assume you have configured Windows Firewall correctly to allow traffic from VMRCplus. Please read the other post if you did not.

When connecting to a remote host from Vista, I got the RPC message even with Windows Firewall set up properly.

 

Scenario 1: UAC is enabled and I am a member of the local administrators group.

  • When I start VMRCplus and connect to a remote host, I get the RPC message.
  • When I start VMRCplus elevated (right click on a shortcut to VMRCplus and select "Run as Administrator") I still get the RPC message.
  • When I start VMRCplus from an elevated command prompt (run cmd "as administrator") it works. ??????????

So it seems there is a difference between using "Run as administrator" on the VMRCplus shortcut and starting VMRCplus from an elevated command prompt.

 

Scenario 2: UAC is enabled and I am a member of the local users group.

  • When I start VMRCplus and connect to a remote host, I get the RPC message.
  • When I start VMRCplus elevated (right click on a shortcut to VMRCplus and select "Run as Administrator") and authenticate to the UAC dialog using a local administrator account it works.

 

So if you run into the RPC message on Vista with a properly configured Windows Firewall, you may want to try the steps above corresponding to your scenario.

  • when trying to connect to a system with a virtual machine, the following error comes up "Source object cannot be converted to the destination type since it does not support all required interfaces."

    any one know what this means?  

  • If you are getting the destination type does not support

    all required interfaces error just uninstall vmrcplus and reinstall making sure you install all options (2nd option in the install) Once done it will work fine.
