I'm moving a PC from one network to another..... RRS feed

  • Question

  • I have an XP Professional PC that is currently in a Windows 2003 AD domain in my current office.  It has an IP from DHCP and it is registered in DNS.

    I plan to move that PC to a totally new network at a branch office.  That branch office is reachable by this office with a site to site VPN connection.  The branch office can see the domain controllers as well.  The PC will be assign a completely new static IP there.

    What should I do with the old DNS and DHCP entries of the PC in this office?  Should I manually delete them?  Or should I run ipconfig /registerdns from that PC to update the DNS?  Should I manually delete the old DHCP lease entry that is left over here?

    However, I can give you a quick answer.  If the PC has a dynamic DNS record, then when it shuts down it should remove that entry from DNS. When the PC comes back up and registers in DNS, it will replace its old record, if still present, with a new record with the new IP address.  If you have created a static DNS entry, you will have to manually update it with the new IP address.

    If you want to manually remove the DHCP lease after shutting down the PC, it certainly won't hurt anything to remove it.
