in an attempt to get ideas and answers to technical problems...I've made a living for a long time by solving other peoples problems...

Ip addressing in each location is DHCP, however, each machine has a "reservation" so it remains constant.

DSL modem/switch in each location is the same...Firewall is a Sonicwall.

The provider XO Communications has reset the line...has logged into the modem and done pings....they say "occasional" request timed out is normal. I think it's a bunch of bull....but they have yet to see a timeout...
