Hello again:
 
So the new server hardware has come in (Thanks for everyone's previous hardware 
input), and now I have to plan switching over the entire farm. The 4 W2K Citrix 
MF 1.8 servers I plan to do first, and I can handle pretty well, but I am 
feeling pretty shaky about replacing the DC's.  I have found a wealth of 
information on thethin already, but I was hoping for some pointers:
 
Current setup:  2DC's, upgraded from NT4 to W2K long ago, and so still named 
PDC & BDC.  Running: DNS, DHCP, AD
 
Current plan:  First:  Demote the old BDC and remove it from the network (reset 
AD), install new BDC & DCpromo it.  This will replicate the AD from the PDC.  
Question #1:  Will it replicate the DNS when it does the AD?
Question #2:  Do the Domain (controller) Security policies get copied during 
this?
Question #3:  Can I run in Native mode if I have w98 machines on the network 
(not a citrix connection, a network connected computer), but everything else is 
W2K, XP, Linux?  (All of the servers are W2K, I'm betting it's already in 
Native mode.  How can I tell, btw?)
 
Next:  Install Term Serv licensing on BDC. Switch over the FSMO roles from PDC 
to BDC, set BDC to run the Global Catalog, unpromote old PDC & unplug it from 
network (reset AD for PDC on BDC), 
Question #4:  Currently, both servers are running the Global Catalog.  Is this 
a good practice to continue?
Question #5:  What problems will PDC have with Terminal Services licensing 
being on the BDC while it's offline?  (I assume you just can't log in through 
Term Services.)
 
Last:  Plug in new PDC, dcpromo it thus copying over AD & DNS, switch back over 
the FSMO Roles & include it on the Global Catalog, set up DHCP, set shared 
folders for Citrix user Profiles & Home directories.
 
This skips a few steps like OS install, SP's, some .bat files, but does anyone 
see something I have overlooked, or know of some good sites that I should look 
at before going through with this?  
 
Thanks in advance,
