as far as I can see the name is immaterial - the thing that matters is if you chose a tld that ever became in use on the Internet. Only then are you likely to have a problem...
if .local never gets used as a tld there's no issue... but to be absolutely sure either register your ad domain name, if it has a valid tld, and never use it on the internet - or make an educated gamble on the tld, choose one like .local or .xyz, not being used during the lifetime of your forest. ----- Original Message ----- From: "Roger Seielstad" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Thursday, December 05, 2002 9:20 PM Subject: RE: [ActiveDir] AD upgrade DNS namespace questions. > Two different groups (each) at with Compaq Consulting Services and Microsoft > Consulting Services.
