Issue:
After creating a custom Administrative Template (ADM) file you receive the following error when viewing configured settings in the Group Policy Management Setting tab
An error has occurred while collecting data for Administrative Templates.
The following errors were encountered:
The .adm file "\\dc01.domain.com\sysvol\domain.com\Policies\{123A30AA-1233-1230-123A-12376B6DBB2E}\adm\Custom.adm" is not in a valid format and must be replaced. Details: A string is expected at line 29.
Cause:
Certain VALUES must have static strings assigned to them and not use the [stings] substitution values like !!Name.
Solution:
Convert all string substitutions for VALUES to static strings.
Example:
The string after the key word “VALUE” must be a static string a not a substitution string (i.e.: !!Name01)
