Demote SBS 2003 Domain Controller from Domain

Hello,

I have a 2003 SBS server which has gone on the fritz. i have purchased a 2008 R2 server which I have made a domain controller.

Will it cause any problems if I demote the 2003 SBS server and reformat it to a regular server (maybe promoting it afterwards)?

Any particular reason for asking the second question?

SBS servers MUST be FSMO master DCs.  While you could demote it and reinstall it, if you fail to make it your FSMO master DC, the server will start automatically shutting down every few hours on you after 1-3 weeks.

Alan, I asked another question because I didnt want to cloud up that last question. You can respond to either, i don't really care.

leew, can I make my 2008 DC a FSMO(how?)? and if so, can I just bring up my current SBS server as a regular windows 2003 server and promote it?

To clarify, I have no need for a SBS anymore.

You can transfer the FSMO roles by following the link below, then run DCPROMO on your SBS 2003 box to remove it from the domain.

Remove Exchange from the SBS 03 box first as per the other question.

Once the SBS box is out of the equation, you can rebuild it and join it to the domain and make it a DC

You CANNOT use SBS as a regular server - it MUST be the FSMO master DC.  The other server can be the TEMPORARY holder of the FSMO roles while you do this, but if you intend to reuse your license for SBS, you will need to make it the FSMO Master DC within 1-3 weeks or accept having the server shut itself down every few hours.

You can migrate from SBS 2003 to 2008 without a problem.  If you wanted or needed, the only way to reuse the 2003sbs box would be to set it up as its own completely separate forest and domain.  As leew mentions, SBS servers of any flavor cannot exist without owning all of the FSMO roles.

Just to clarify as bit, if you want to demote your SBS server and then remove it from your network, that is perfectly acceptable as long as you trasnfer the FSMO roles and make sure your new DC is a global catalog server, as already discussed.

You can also use the existing hardware to install and run Windows Server 2003 if you so choose. The *prior* existence of SBS on the network does not impose long-term and outstanding rules on the network. Once SBS is removed, those restrictions are removed as well.

What leew is saying, and he is correct, is that your SBS license does *not* entitle you to run a standard edition of Windows Server 2003. You must have a separate license if you choose to run this OS on your old hardware. SBS licensing does not allow you to pick and choose components. It is an all-or-nothing install. So if you choose to remove SBS from your network, you are discarding that license and will not be using it at all. As long as you have some Windows Server licenses though, you can proceed with your plan.

Thanks Guys, And thank you once again cgaliher.

I awarded cgaliher the best answer as he noticed my post saying I didnt need SBS anymore. Although I suppose I could have qualified that I own a few copies of windows server to replace it with.

Thank you for the link to transfering FSMO roles and clarification on that I only need to do that and make it a GC.
