Creating domain in a poluted namespace.

Hi hope to get some ideas on this issue, I have come into a network running Netware 5 and many Unix, Win2K standalone servers and an NT 4/Exchange5.5 server all sitting in various workgroups like 'myfirm' etc.... A netware server does DNS and thinks its the authority (according to nslookup) for 'myfirm.com'.
I need to setup an AD enviornment and installed a Win2K3 server, setup DNS and did a DCPROMO. DCPROMO was able to set the FQDN to 'myfirm.com' however the Netbios name chosed by DCPromo was myfirm0 due to conflicts on the network.
My question is how do I install and run the Win2K3 AD with the domain name/Netbios name I want ?

I would make sure there is nothing more than a workgroup using the betbios domain name because it simply wouldnt workout otherwise. If this is being caused by some samba domain emulation or wacky novell thing you may have to segment the network to seperate the netbios traffic between the 2003 an the other systems temporarily, or use different addressing and make an address change for clients part of the migration.

The Netware server does DNS and I have looked around and the Exchange server is running on a PDC.
I suspect I will have to upgrade the PDC or can I join the existing domain?

No problem. Do this.. Add your server an an Nt4 BDC. Switch to to the PDC and then upgrade the new server to 2003. Its a pain but it will work. The major benifit of this method is that you dont have to mess around with the existing PDC beyond switching roles to BDC. Reversing the domain upgrade is as simple as, disconnect the 2003 server & switch the old pdc's role back to PDC.

I may try that, Today I managed to install it as a 2003 server into the existing domain and will try to run DCpromo and may manually add the users. Any thoughts there?

Thoughts..yes.. You cant run DCpromo because it will create a new domain and not upgrade the existing one. I would do the NT4 thing personally.. If you are going to go the new domain route, then I suggest ideal migration utility.. It copes the users, passwords....everthing..

Now I may be whacky here but this domain does nothing other than authenticate for Exchange, (Netware is currently the real deal here), I have thought of backing up then upgrading the existing BDC to 2003, running the DCpromo if I have to, then later after testing running DCPromo on the new server which has 2003 installed. Any merit to that plan, pros cons? Your input is appreciated. Thanks

Upgrading an NT4 DC is the point, so your idea is valid. Pro's... NT4 BDC is already setup and probably fully replicated :), less steps to complete 2003 upgrade of the domain. Cons are, if you intention is to use the new first root server as a temporary measure, you will have to move all the FSMO roles. Not a big deal, unless there are problems with the 2003 domain. Generally you want the first server to be a long term production box because at best after it is removed the remaining servers will complain a little about missing this and that.. Not real problems, but then again if a real problem does occure you event logs will be that much more difficult to decifer. Just my opinion..
