Sorry for the late reply but.....

In the case of remoting, the Trx boundary is the physical machine. So a
"client" machine starts a trx, then remotes to "server" machine. The trx
boundary for the client is that clients physical machine. If the "server"
starts a trx, its boundary is its own physical machine (assumnig you are not
using COM+ and DCOM to span machines and similar methods). In ADO.NEt you
can start a Db trx from a machine, which goes to the DB machine and performs
the transacted operations so it technically spans a machine boundary but its
also not remoting.

Hope thats clear. Basically, remoting means trx boundary is limited to that
physical machine.
