You are unable to access Cisco Unity Server through windows Remote Desktop Connection.
Complete these steps:
On the Cisco Unity Server, right-click My Computer and choose Properties. In the System properties window, go to theRemote tab.
In System Properties > Remote > Remote Desktop, ensure that the Allow users to connect remotely to this computer option is checked.
This issue can also occur due the Browser service, which gets locked up during the logging process. The Browser service maintains a list of computers on the network and supplies this list to Computers designated as browsers. The Browser service follows a certain election procedure that ensures that the "important" computers (i.e domain controllers or servers vs workstations) are always elected first as browsers for the network where they reside. This service should be stopped if you do not want the computer to ever attempt to be a browser for its network segment
Complete these steps in order to resolve the issue:
On the Cisco Unity server, choose Start > Settings > Control Panel > Administrative Tools > Services.
Right-click on the Computer Browser service and choose Properties. In the General tab, change the Startup type to Manual. Click OK.
Right-click on the the Server service and choose Properties. In the General tab, change the Startup type to Manual. Click OK.
Right-click on the the Workstation service and choose Properties. In the General tab, change the Startup type to Automatic. Click OK.
Reboot the computer.
When RDP is used to connect to Cisco Unity, this error message appears:
