I have to rebuild a file server from the ground up.  This server also functions as our DNS server.  Is there anything I need to get out of there so that I can restore DNS as soon as Windows is reloaded.  IE...zones, etc....

Can you please be specific on how to get the info that I may need out...

Presumably nothing to do with Active Directory?

Is the old server still running? Will old and new be running in parallel?

DNS configuration is stored in the Registry, and Zone Files as files in %SystemRoot%\System32\DNS. Depending on your situation you could export the registry settings and grab the files, or we can script a copy of the zones. Just depends how it's going to work.

Well the server that I am rebuilding is a DC, file server, print server, DHCP and DNS.  There is another DC that I will not be working on and was thinking that the AD would rebuild through replication.  Please let me know what your thoughts are on this.  I am just finishing up with the robocopy on the shares.  After that my plan is to blow out the array and rebuild from the OS up.  Any suggestions on easing the pain here would be great!

DNS will be fine after AD replication as well (if all are AD Integrated Zones).

DHCP can be moved if you're in the mood to do so, the following KB article describes how:

Robocopy is the best I'd be able to suggest for copying across the files. Are there a large number of shares? If there are they can be created with a script rather than manually.

The Printer Migration Tool should be able to shift your printers across, of course if there are only a small number it may just be quicker / easier to do that manually.

Remember to make your additional DC into a Global Catalog (through AD Sites and Services) if it isn't already. And if the server you're rebuilding is the first in the domain, you'll need to Transfer the FSMO roles over as well. Ideally, run DCPromo on the current server to demote it prior to its rebuild.

Most DNS problems are VERY easily troubleshot and identifiable if you can follow the steps a DNS query takes. I would like to share the step-by-step a DNS query takes from the origin to the destination. _____________________________________________…
If you have a multi-homed DNS setup in windows, you can have issues with connectivity to the server that hosts the DNS services (or even member servers of your domain if this same DNS server is a DC). This is because windows registers all of its IPs…
