Hi A few months ago we installed a new exchange 2010 server with our exchange 2007 server and they have been coexisting for the past few months with out an issue. Now the past 2 weeks at random times the exchange transport service on the 2010 server just stops and nothing we can do besides a total reboot to get the service to start again. In the error logs it says that it cant contact any of the domain controllers! I can still get online and ping the domain controllers so its not network related i don't think. I have tried a different nic, different switch port. I also made a new store data base in cause there was just too many users in the main store we have.
Out current configure on exchange 2010
4 database stores
96gb of ram
24 logical procs x64bit
5 tb of available disk space for exchange
I get this error befor it starts to get bad. Event id 2102
Process MSEXCHANGEADTOPOLOGYSERVICE.EXE (PID=1924). All Domain Controller Servers in use are not responding:
any ideas on what else i can check?
