I am at wits end and desperate....
I uninstalled Proset 13.1 on my server 2008 (x64) and rebooted. Then installed Proset 13.3 on the server. Upon completion, device manager shows that the OS cannot load the drivers for both ports of the NIC with a code 31.
I rebooted the server and now I cannot access the properties page of the NIC on device manager. When accessed, the device manager will just hang. Attempts to uninstall the Proset failed as well, with the process stayed at Preparing to install..... etc.
