Glenn,

Thanks, I tried this and it didn't seem to work. I tried the information in
another response I got and it seemed to do the trick. The problem was
this:

**********************

>From the description, I understand that you encountered a problem in GPO.
When trying to modify (or create) a group policy with Active Directory
Users and Computer or Group Policy Management Console (GPMC) the error
"Failed to open the Group Policy Object. You may not have appropriate
rights. "The parameter is incorrect" occurs. If I am off base, please let
me know.

In order to isolate the problem, please follow the steps below:

1. Can you open a new Microsoft Management Console (MMC) and add the
Group Policy Object Editor" and modify and/or create group policies in
Active Directory.

2. If so there might be caused by the register error. We may go ahead
to check a value in the registry:

HKEY_CLASSES_ROOT\MSCFile\Shell\Open\Command

Could you tell me what the value for default is.
It should be %SystemRoot%\system32\mmc.exe "%1" %*

3. If the you get an "Access denied" error when edit GPO after
changing please do the following
HKEY_CLASSES_ROOT\MSCFile\Shell\Open\Command
%SystemRoot%\system32\mmc.exe "%1" %* and made the key a REG_EXPAND_SZ
type.
