Cisco IP Communicator on Windows XP Black Screen Issue

Howco asked

Never seen this problem before.

We have a remote office where everyone uses softphones using Cisco IP communicator.  All other phones have installed correctly previously.  This means that there are no routing issues to the CM server.

However, on this one PC we installed the softphone and when we run it we get the software showing with just a black screen.  The PC can tracert and ping the CM server and vice versa.  The SEP code is showing in CM.

There are no entries in the Hosts file.

When you dial the number of the softphone it goes straight to VM.

So I am completely at a loss!!

All help greatly appreciated.
