Hi Darren, I think the GPO was corrupted in the sysvol on the DCs. It took a few hours, but the reason I think this is that it replicated out to several of our users at sites throughout the company.

Date: Mon, 5 Feb 2007 08:08:33 -0800 Most of the "corruption" I've seen has been where a particular CSE is unable to read its settings files. The files are there, but not in an expected format. And they bomb out as a result. I suspect that is what you're saying, though I honestly don't know why. Do you see any difference in behavior if you add exception in groups. For example, you add 10 exceptions, then hit Ok, then add 10 more, then hit OK, etc. I am just wondering if it's a buffer overflow on the process that adds the settings into the registry.pol file, since I don't see anything explicitly in that file that would limit the number supported. Frankly, I would call MS on this one because I think it sounds like a bug to me. Let us know what you find. Darren Mary Collingwood We Energies - IT Services Client Device Integration
