We are migrating users from domain/forest A to another domain/forest B. Domain/forest A has three child domains. Users on two of the child domains have been migrated but is a smaller population which the DC's and users are on the same network. The third domain, (larger population and multiple locations) the DC's and users are on different networks and the migration team are having issues migrating the user computers. At first the team thought it was because the DC's are not on the same network as the users. They then though had to enable wins for the short name since they explained Quest tool needs short name and can't ping the domain name. Short name should work with DNS as well. The team setup WINS replication between to two Domains/Forests but they still have the problem. The team also enabled wins because they thought the migration of the users computer needed to be able to ping the domain name for domain/forest B.
Can someone explain to me how does the Quest migration tools work to migrate a user computer in an environment the users and DC's are on different networks? How does short name play into migrating the user computers? What needs to be in place to migrate the user computer?
