BIP8634
Severity
0 : Information
Message
Setup of NT Security groups failed. Reason: <insert_1>1
Explanation
There was an error encountered when the installation program attempted to set up local NT security groups, or (if you are installing on a primary or backup domain controller), global NT security groups. The reason given in the message gives further information about the cause of the failure.
Response
The installation continues, however you may manually have to create the necessary groups using the Microsoft supplied User Manager Tool accessible through the NT toolbar. The installation manual gives more information on the names of the groups and how to do this. If the reason is 'Failure in adding global groups to local groups' then this may reflect a valid situation where a decision has been made not to implement the security model using global groups.
