Exchange2007 cant see or relay on 2nd GC/DC

I have exchange 2007 on a separate box and a second box that is hosting the GC/2003 STD.  However for redundancy I decided to add a second GC/DC just in case if the first one dies then exchange will switch to the second automatically.

Last night for testing I shut off the first GC/DC and exchange did not switch and I could not receive emails because it could not find the first GC/DC.  

In Exchange management tools I do see booth server names under server configuration-->client access-->name of the server on the top---> system settings tab  I do see the second DC/GC name...

In other words exchange can see it but its not switching to it when I turn off my first GC/DC
Any ideas?
Thanks

Exchange should automatically detect new DCs & GCs in-site and out-of-site, this AD topology discovery process runs every 15 minutes and you can see an event in application log 2080 with source MSExchange ADAccess.

To resolve the issue you are seeing, Enable the following on the GC's.

Have the Security Group "Exchange Servers" Enabled under:

Local Security Policy

Users Rights Assignment > Manage Auditing and Security Log.

Applying the Exchange Servers security group to each DC policy fixed the problem.

Thanks for your help, the group was found under the domain controller local policy(booth servers).. However, it was NOT under the domain policy.  I did add it under the domain policy.. hope this will fix my problem.  I will test soon.
