my thought would be to start more of a right(computername,1) = right(IPaddress,1). Yeah, if the computername was ABCCOMP111 and it's IP was 10.0.0.1 it would match, but I could live with that, I'm trying to determine what machines don't match their IP so we can change them, and anything I can do to help identify them in Lansweeper is great.
