We have several hundred windows XP clients that are used in Lab and Classroom settings. These machines are protected by Compguard Cornerstone (a drive protection software). Within the last 6 months almost all of these machines began falling off the domain every 30 days. I did some reading and the drive protection software manufacturer recommends disabling Machine Account Password changes since the protection software would revert the machine to it's old password after a reboot - post password change.
After reading up on the Machine Account Password GPO settings, I placed a GPO in the OU in Active Directory which contains our protected machines. I adjusted the value of "Disable Machine Account Password Changes" to 'Enable' which should prevent the machine from future changes.
I logged into a number of these machines and the GPO was indeed being applied; however, yet again after 30 days, all the machines start to fall of the domain!
Am I missing something? Is there another step that I need to take to get these machines to stop changing there account passwords?
Any help would be much appreciated!!
