SAGE Login Page taking long time to load after taking down secondary DC

Hi,

I'm hoping somebody is able to assist on this matter, ever since we migrated our secondary domain controller to a new one, our SAGE login page (version 7.4) is taking a real long time to load.  Anywhere from 1-3mins.  We have verified the at DNS is configured properly.  We have tried migrating over to another VM host, created Test VM SQL databases, tired modifying the DNS entries, etc. but still no luck.

We are really lost at this point as nothing is wrong with the performance of SAGE, once logged in it is working fine.  Just the initial login page is taking a long time to launch, does anybody have any ideas why it is taking such a long time for the login page to launch?...What components is the Sage login dependent on?
