My client has relocated his small office (5 Users) into a home in a
residental area from a small industrial area.

It appears that during periods of inactivity, the DSL line is dropped and
there is sometimes a delay in re-connecting to the ISP and the Internet.

I believe this is the cause of the NDR's from the server.

Since this was never a problem before, and I've never had to deal with it
before, i need help.

What settings do I need to adjust to the number of retries Exchange does
before sending an NDR and how to set Echange to try and try again for the
internet connection.

I hope I have explained this well,

Thanks

Doug Sanders
