check the fsmo roles.
also check the GC fole.
these must be with the DC/GC that is working right now

are all the exchange services running?
have you rebooted the exchange server after DC change?
any errors in the application log?

Process MAD.EXE (PID=2184). All Global Catalog Servers in use are not responding: (the new PDC)


Process MAD.EXE (PID=2184). Topology Discovery failed, error 0x80040a02.

shutdown the GC and the exchange server
after that start the GC. once it has rebooted completely, start the exchange server.
let me know the status after that.
