Great Thanx.
While setting up /domainprep I got the following Message and just wanted to know how to solve the problem
The domain "company.domain.com" has been identified as an insecure domain for mail-enabled groups with hidden DL membership. Hidden DL membership will be exposed to members of the built-in "Pre-Windows 2000 Compatible Access" security group. This group may have been populated during the promotion of the domain with the intent of allowing permissions to be compatible with pre-Windows 2000 servers and application. To secure the domain, removed any unnecessary members from this group.
thanx,
M
