I am tryign to determine the effect of renaming our client computers. Currently all computers are in collections in SMS, we are looking a re-doing our naming convention to better describe the location of the clients. What I am wondering is what the ramifications of renaming clients that are already existing in SMS collections? What happens if we re-use a name that currently exists for a different computer? I am assuming SMS uses a machien SID or some other non name specific tracking method but I want to be sure before renaming 1000 computers.
