Process MAD.EXE (PID=2184). All Global Catalog Servers in use are not responding:
domain1.abc.com
domain2.abc.com
domain3.abc.com (the new PDC)

--------------------------------------------------------------------------------------------------------

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

that means that there are still some roles on the old server. install and run the following MS tool.
let me know what it reports
