Machine lockout (set to 1800 seconds) locking after 60 seconds (because of old GP setting)

I am stumped by this issue. I have recently been experimenting with screen lockout policy on a machine, I set the policy on a test OU where the machine resided to lock this machine after 60 seconds.  This applied successfully, later, I then not only deleted the policy, but I moved the machine back into the OU it was originally in, so that it picks up the old policy that sets the lockout to 1800 seconds.  The machine still locks after 60 seconds (it has been rebooted around ten times over a period of a week).  I checked the following on the machine -

Registry - set to 1800 seconds
RSOP.msc - picking up correct policy and set to 1800 seconds
Control Panel, Screen Saver - set to 1800 seconds

I searched the registry for another instance of screensavertimeout and the only one that exists is the one in question i.e. HKCU:\software\policies\microsoft\windows\Control Panel\desktop

Any help would be greatly appreciated.

I had this happen before also. I never did find a correct answer to it. My work around was to move the computer(s) in question back to the test OU, build a GPO that sets the time out setting back to disabled. This removed the test setting. The once I moved them back to a production OU, the correct setting took.

Load up mmc and then add GPO editor for local machine and have a look a whats happening on a local level.
What happens when you run a GPO molder from your AD server on the machine?
Is the other GPO still lurking? The molder will tell you what the name is of the winning GPO.

Thanks very much for your response, it seems to be OK now and all that has really occurred are a few more reboots and 24hrs.

Sorry Stolsie, only just seen your comment -

- That's what RSOP does.

Not sure what a molder is.

Just had a look at RSoP and so it does, I’m old school I’ll have a look what the difference is in the reports :)

If a few reboots worked had you not done gpupdate /sync and/or force on the command line? (Sorry should have been the first suggestion)

for molding you need to open up group policy management on your DC underneath forest in the left hand column you will see "group policy molding" there you can query your machine based on DC, User, date time, all sorts.
The pages will show you what is set on your machine and by what policy

FYI
RSoP misses out a fair amount of setting.
have a look add GPO and set it for your local machine and do the same with RSoP
