Hello,
I'm getting some DNS errors (7050) in event log from 1 Windows domain controller running a global catalog. We have multiple switches and firewalls and routers in our network. We are a Microsoft and Cisco shop.
When I run the ping -l 4096 to the Front End Exchange server I get a 25% packet loss. There are no hops between both servers. If i run a ping command there is 0% loss.

What could be causing a packet loss and where should I begin?
