Because our options are slim for good, high-speed internet in our office, we chose to try out a Verizon 4G MiFi hotspot as our default WAN connection, and relegated our much slower T1 as a secondary WAN2 port. I have incoming and outgoing SMTP through the T1, but everything else defaults to the 4G WAN (which we get roughly 15G down and 10-15G up!!).
I noticed last night that large amounts of data were being used on the 4G, despite anyone being there. I'm assuming WSUS might have been downloading updates. I've temporarily stopped WSUS services to see if that helps.
My question is, what else on a SBS 2008 server could wind up using a lot of internet bandwidth? (We don't use Sharepoint and Remote desktop sessions go through the T1).
Thanks for any help on this.
