Currently my envirenment is 1 2008 64 bit master server(version 7.5.04) and 1 2008 r2 media server(version 7.5.04) We recently upgraded to Vmware 5.1 from 4.0 around August in which we changed the name of the server. So in the master server administration console we added the new name and kept the old
one in there also. Now we are unable to restore vm images past august... Is there a registry change i need to add? I have looked through documentation but havent came up with anything. Error is below:
