Switch stack reverted to old IP.
A couple of switch stacks of ours have reverted back to an old ip that is no longer in our scope, although it's the same subnet mask, which is why I guess they're communicating with stacks on the new scope?
Could this be causing a massive problem we have with our network almost grinding to a halt for 5-10 minutes while classes are logging on, like a bottle neck effect?
One of them has all the servers patched...
Found out late yesterday about the switch and obviously not in until Monday.
Hoping if I change the ip back it will sort itself out.
