Our Company A is going to purchased by Company B. Both of us are on Windows 2003 domains. During the transition period, we will have a 2-way trust between both domains. Eventually, all servers from Company A will join Company B's domain. There will be new user accounts setup on Company B's domain. Is there some type of utility out there that I can use to match up existing Comany A accounts with the new Company B accounts so I can maintain and copy the same NTFS permissions for users on files and folders after joining the new domain?
