Last week we had an incident where one of our DC's was rebooted without our knowledge and so we had issues with the BES until it was rebooted. I found a registry hack that supposedly forces the BES to look for another DC. I applied the fix to one of our servers, and then created a host entry to point to the DC to which the BES is currently attached. I then changed that host file to an invalid IP. If I ping that DC from the server, there is no reply; however, I can still send/receive from my device and I see no events stating that the DC was lost.

Does the BES use something else to resolve DNS?

Thanks! I had read this thread previously as that is how I found the reghack for Exchange 2007. I applied the hack on Friday and restarted the services. This morning, I wanted to test so I created that incorrect host file entry. I cant ping the DC now...which is what I wanted...but I guess the BES is still seeing it because I was still able to send/receive and I didnt see any issues.

Do I need to drop the NIC or something?
