Active Directory Server Failure

Hi Yesterday my server crashed and if you look at my history I have had some great help trying to get it restored.

On my secondary server I though I had AD replicated. When my main AD server crashed nobody can authenticate on the second server and I cannot open AD - it says domain not found.

I tried to configure DHCP on this machine and got basically the same message - "cannot contact AD"

My DNS seems okay on my second server and I configured the users to point to it and my gateway.

I ended up configureing my router to be a DHCP just to get empoyees online again.

Nobody can access my second server (Dell2) and AD is not showing up.

I am asuming this is where I have to sieze (or transfer) the rolls over to this server.

Whts the point of having ad replicated to two servers if one fails and you have to do all this? Or am I missing some basic knowledge or configured it wrong?

Thanks

If your primary AD Controller is still offline, you need to seize the FSMO roles on your secondary AD Controller, yes.
The point of replication is that you have a functional AD right now, you just need to let your secondary server know it is now the primary server.  AD still points to FSMO for authority, and in the absense of FSMO, AD will fail.  It is similiar (though completely different technically) in idea to a BDC in NT 4 which has to be made a PDC if the PDC crashes.
Here is a good link on how to seize the FSMO Roles:

Thanks for the clarification - I just got the old server online with Mkline71 help and will keep working on it
