If you are the administrator for a group, and you try to update or try to modify a corrupted Registry.pol file for either users or computers, you receive no warning that the Registry.pol file is corrupted while you edit, save, or apply the policy file.
This issue occurs when an administrator modifies the Group Policy settings under the Administrative templates node and then updates the settings for either users or computers. These changes are then written to the appropriate Registry.pol file.
If this Registry.pol file becomes corrupted before the new settings are applied to the users or to the computers that are affected by that policy, the new changes to that policy are not applied.
There is no workaround for this issue. You must re-create the Registry.pol file. You can detect that the Group Policy editor did not successfully open the Registry.pol file by enabling user environment logging on the client computer.For additional information about how to use the Userenv.log file to debug policy problems, click the following article number to view the article in the Microsoft Knowledge Base:
