Manually change ldap dns ip without logging in to manage engine service desk?

We recently installed 2 new 2008r2 domain controllers in our domain, transferred the fsmo's and removed the old servers from the network. Unfortunately the ip for dns was not updated in service desk, so now no one can log in to include the default administrator account. I wanted to know if there was a configuration file somewhere that the ip for the current dns server could be updated in.
