Hi Bob,
yea I changed that today and ran the Fix my network app in the SBS
Console.
The DNS and DNS reverse lookup were corrupt so it reinitialized that. I
found
that when i disable my IPv6 my exchange doesn't work at all. Thanks for
the
help will let you know if the dns fix sorted everything out.

The DNS could be the problem. It is recommended to use internal DNS
instead
of ISP DNS. Also disable IPv6 for a test. Please post back with the
result.

There arent' any errors in the Event Viewer, but i do find it strange
that
absolutely nothing gets logged when the server looses the network
connectivity. here is the ipconfig / all

Hi All,
I am having a problem with my mail server that I cannot figure out
why.
The
server runs fine for a few days and then all of a sudden I cannot
access
to
the server via the network (local or external). When i restart the
server,
it
seems to sort itself out for awhile and then this will happen again.
All
hardware is fine, I have tested everything. Any insight to this
would
be
grately appreciated.
