Thanks for that. Just for the record, and for anyone else reading the archives... I found that the most useful value for $reason on the systems I am using was not BOUND or REBIND, but REBOOT. Also, my "host" command obviously returned different text to Jim's, and I needed to change the s/Name: //p to match the different text. (Sorry I do not have easy access to the actual script at the moment, but the changes were not difficult!)
