I am tryng to create a BLPackage for Windows 2000 Server using the Account Policies listed under the Security Settings. I create the package, then put the package into a job. Execute the job it indicates success. I check the account poicies on my target server and nothing has changed.
Do you have the CIS Templates loaded by any chance? I think that a lot of the remediation packages that are included with those templates update account policies. It might be worth digging around through those to see what your issue might be.
