Controllers offline and getting the error "due to an unidentified problem, windows cannot display firewall settings" when trying to access the Windows Firewall

Issue

All Controllers have recently gone offline to one Cyberstation and get an error trying to access the Windows Firewall

Environment

Windows XP

Windows 7

Windows Server 2003

Windows Server 2008

Cause

The Windows firewall has become corrupted either by a bad sector on the hard drive or by a virus/malware

Resolution

Check the Windows event viewer application and system logs to see if there are errors that happen when accessing the Windows Firewall. For example, if there are bad hard drive sectors, run a chkdsk. Take the appropriate action to correct the issue.

Run Antivirus and ensure the PC is clean

Run Anti Malware software (Ex. MalwareBytes, Spybot, etc.) and ensure the PC is clean

Repair the Windows Firewall http://support.microsoft.com/kb/920074

A couple of other options would be to go to a Windows Restore point prior to the issue or Format the Hard Drive, reinstall Windows and Cyberstation.
