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.
