Many have apparently experienced this error, but I find no credible cause/solution? This started occurring for me the other day after creating a Group Policy. I didn't do anything unusual and now anytime I go into the Group Policy management console and click on a GP, I get the error below. Clicking OK bypasses the error and everything seems fine, but it happens again whenever I select the same or another GPO. The KB article doesn't really apply since we're already running Windows 2003 SP2.
"The permissions for this gpo in the sysvol folder are inconsistent with those in active directory. It is recommended that these permissions be consistent. Contact an administrator who has rights to modify security on this GPO.
