new domain controllers, need to keep old IP addresses.

Mind the AD tombstone lifecycles, a full cycle will take about 90 days after that you can be confident that everything's OK.

Another one, why do you still use wins servers? Unless you don't have stone age machines (pre win2k) or special applications which rely on netbios you don't need it anymore, DNS does the name resolution for you. (Netbios over TCP/IP)

Mind your dhcp and verify you *really* don't need it. Less overhead, broadcasts and traffic as well as vulnerabilities on your network. :)

In the SonicWall tab the DNS & WINS tab are side by side. Remember when I mentioned ipconfig /all had rogue DNS entries?

I just updated the two tabs with the new DC IP configuration. Come to think of it, unless Server2012R2 automatically applies WINS, I don't think I have any WINS server at all.

Do you think it is possibly still taking up resources if the IPs are just listed in the WINS tab configuration on the SonicWall? I can remove them, but mehhhhhhh
