For some reason after I use regedit and make the change to NTLM  changing from 5 to 1..it works for the whole day but I come in the morning and the settings have reverted back to 5...We use a web filtering system tha t requires the authentication to be NTLM ---this scenario is only happening to our windows 7 machines...How can I permanently change the registry to reflect the "1" value.....these machines are part of a domain...but our XP machines do not need to be changed at all ....Does someone know the proper way to FORCE the change to the registry permanently?  Thank you...

It sounds like there is something resetting your registry settings to a pre-established baseline, such as the periodic Group Policy refresh.  Download the spreadsheet that applies to Windows 7 from this Microsoft page.  It shows the registry entries that apply to each group policy, so you should be able to perform a search to find the proper group policy and then see if it is currently set in your current Windows environment:

Hi there....I know been a while since I last wrote on this issue....
Even with making the changes to group policy, the local machine is changing the registry setting back to the default value of "5"   ....I need to come up with a solution that is permanent as long as we have to use this web filterer......

If there is a group policy refresh that is overridding this change to my local machine, is there a way to have the local machine to have a higher priority  for this registry key?

I am a little concerned about making a change for the the OU on the Domain Controller that I have my Win7 machine in only because the DC is on a Win 2k3   OS.
Thank you for your help!

You could potentially move that machine to another OU, perhaps even a new one for testing purposes.  Once it's created, you could block/deny OU inheritance as you see fit and experiment with whatever works best.

Thank you ...after trial and error.  and the advise of blocking inheritance...i was able to get the registry key to stick....Also the link for all the registry and group policy settings is what made me find the correct selection for this particualr problem.  Thank again!!
