I'm having problems where a running backup process is interfering with our Nortel Voice over IP system. I'm conserned about this because all of our servers are on the same switch, but traffic seems to be leaving the switch and interfering with the rest of our LAN.
The only other potential source I can think of is that our server's NICS are teamed, but the switch they are on is unmanaged, where our backbone LAN switch is.
Does anyone have any idea why this is happening?
