Very very interesting adventure.
Sudden internet packet loss 2 days ago.
No packet loss when hooked up directly, but packet loss when through router.
Talked through with ISP tech support
Finally replaced router, seemed to fix but seemed odd
Ran fine for 1 day
Packet loss today.
Replaced the ISP's modem, no significant change
Dealt with tech support again, traced back to Server... seems infected and is flooding the connection.
I don't administer the server. When i log in, I notice that Microsoft updates are off.
I'm wondering if there is a way to block outbound ports to contain the infection long enough to update SQL and disinfect.
