Hello, 
They have one forest and one domain...no child domains at all. 
Just these two servers and that is it. 
The DNS is not an integrated zone. 
Thanks,

If the DNS is not Integrated is separate or configured as primary / secondary (old school)? 
 
If it is not AD Integrated do the DNS Zones managed match the AD DS naming convention? 
 
I prefer AD DS integrated. 
 
I would keep the primary secondary zones setup but install two servers of 2008 R2 SP1 and use Integrated DNS on those servers for the new domain. 
 
I assume your goal is Functional Level of 2008 R2 Native Mode? 
 
Btw, right after you do this you should start planning for 2012 Migration. &nbsp;Your already behind. 
 
I would use Integrated DNS for the FOREST. &nbsp;You can also sync your other zones as secondaries to both 2008 R2 servers simply by installing DNS first. &nbsp;Replicate DNS. &nbsp;Then DCPROMO but use INTEGRATED DNS for the AD Zone, DCPROMO and point to the legacy DNS servers initially. 
 
Transfer the FSMO roles (aka SRV records). &nbsp;Add the DHCP role to both 2008 servers, activate the role, add the scopes but don't enable them yet. 
 
Transfer the Schema Master Role. &nbsp;Downpromo the 2003 DC. &nbsp;Verify removed with dcdiag. 
 
Upgrade your domain functional level to 2008R2 
 
Change your forest functional level to 2008 R2 native mode. 
 
Keep DNS and DHCP on the 2003 servers for now. 
 
Pick some scopes on DHCP, move them to 2008 R2, change IP HELPER IP for those sites or subnets. 
 
Migrate 
 
Repeat 
 
Shutdown 2003 servers

Hello all, 
I inherited a client that has a Windows 2003 that is running AD, DHCP and DNS. 
They also have a Windows 2008 server that is just a server. &nbsp;It is not in AD has no DHCP nor DNS on it. 
Obviously I need to install AD on the 2008 server then transfer the FSMO roles from the 2003 to 2008 server then demote the 2003 server. 
No problem there. 
My question is about DHCP and DNS. &nbsp;Do i install those two on the 2008 server after I install AD on the server, correct? &nbsp;Then do I uninstall DNS and DHCP from the 2003 server all before I transfer the FSMO roles? 
Since this is all on the same network (all on the same switch) of 20 PCs and these two servers how long should I have to wait after I install AD, DNS, and DHCP on the 2008 server before I uninstall them from 2003 server? 
Thanks, 
Kelly W.
