Al this in not a priority for us now. Earlier i was unaware of our VPN
Box settings thats why i was a bit confuse about why these machines
are registring there own records in my DNS.

Also i am not going to uncheck Register in DNS check box on Client
machine as this is not required as if now.

I have already set lease period as per our organizational requirement
so, again i will not do any change unless it is a must required thing
to do.

Al i would surely want to have a look on KB you refered to. If
possible, do me this favor.

Thanks for all your help!!!
