active directory dcpromo gone awry

2 2008 dc's in the orginal domain.  situation is this.
no good backup of c drive on original domain controller.
c drive has been wiped
on dc number 2 dc1has been deleted in active directory users and computers.
it seemed to work ok.  i don't see records for dc1 for kerberos kpasswd or ldap.
there is one service record for _vlmcs left over from dc1.

can i delete it.
right now we are reinstalling 2008 on the c drive on the blown up dc1 and plan on making it a dc with the same name.  anything i should be aware of.
time is of the essence.

You need to insure two things: 1) your second DC which is still running needs to host ALL FSMO roles and 2) you need to make sure your metadata is clean of any mention of your failed DC.

To clean up your metadata:

To seize your FSMO roles:

Make sure you have done this before adding your old DC back into the mix.  Remember to make it a member server before you try to make it a DC, or you will be creating a duplicate AD domain.

If you do the above like DrUltima stated you can move forward with promoting the system again.

I would run a dcdiag before promoting to make sure everything is functioning.

dariusq makes a good point.  Make sure your AD is healthy and stable before you add the first DC back into the mix.
