Hi Guys, firstly, i will apologise for this probably rather lengthy description of the problem, but really want to get it sorted properly.

Anyway, situation is, we have 2 Win2k domain controllers, one acting as a PDC emulator and the other acting as a BDC emulator (i know PDC and BDC are no longer used, but for the case of my sanity, i'll be using them in this question lol) anyway, needed to take down the PDC for a complete rebuild, therefore, i have been in the process of moving across the FSMO roles and GC to the BDC (with intention of making it the potential BDC.

Anyway, currently, the old PDC is set to be the primary DNS server aswell, and it was the only DNS server on the network at the time. Anyway, i installed the DNS server option on the other server ready to do this, and just left it for a while with the intention of doing the migration at a later date.

Anyway, last night after hours, i used http://support.microsoft.com/default.aspx?scid=kb;en-us;280061 to help me do the migration. Half way through the list though, i encountered and error. the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\DNS Server\Zones key could not be found on the original PDC server, but when i looked on the new one, it was there! I continued anyway, and once it was completed, the zones had not actually been transferred across. As u can imagine, i was extremely confused, so retraced my steps and decided to tackle it today.

ANYWAY.... after doing some investigation, i think the DNS server is running on both machines now, active directory integrated, although the old PDC is still set to be the primary DNS. I looked in the settings of each DNS server, to find out that on the potential new PDC (the BDC) the "allow zone transfers" option was not enabled, yet it was on the other one, which could explain the missing registry key!

basically, i want the outcome to be that the BDC takes over the DNS role completely whilst i rebuild the old PDC *(which when built will become the new BDC).

SOMEONE PLEASE HELP! (if they can understand a word of what i have just said!)

Thanks, Gavin
