Master Server OS is Windows Server 2008 R2 Standard SP1

Unable to login to the NetBackup Administration Console
Receive the login window.
After username and password are entered the Login in progress... appears with the hourglass activity and thats as far as it gets. Hourglass activity just continues with no response
The Windows logs show no errors
Backup,Archive,Restore utility works fine and backups appear to be running.
No changes have been made in the last six months.
Plenty of available disk space on the Master server.
He meant run the program as administrator. Shift + Right Click -> Run As Administrator . It is possible that some patching may have changed security permissions.
What does the CLI show while you try to login and the loading screen just sits there?
I'm not sure how much you'd see from java logs on the master server but you could give that a try.
I'd also take a look at the admin logs located at INSTALL PATH\NetBackup\Logs\admin
If none of those directories exist, create them.
