Thank you for posting in SBS newsgroup.
From the description, I understand the network diagram is as following:
modem - linksys router - external adapter - server(sbs 2003 standard) -
internal adapter - switch - workstations
and your current issue is you got Event id 7062 on SBS. Do you mean the
event occurs only when you put the modem into bridged mode and setting the
router to PPoE?

3. Notify lists of primary zones. (If this server hosts a primary zone and
it uses zone transfer)
