Firstly, ensure that your clients (workstations, member servers and DCs) point to both DCs for DNS if you are using AD-Integrated zones. If they are, then the problem is likely DSACCESS/ DSPROXY. What version of Exchange are you running (including SP level)?

Also, is DSACCESS statically configured or set to automatically discover?

Also, ensure both DCs are fully up and running (DCDIAG /TEST:Advertising)
