SBS2008 Server's looses network connection

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.

We need more information to help. Any errors in the Event Viewer? Or posting
the result of ipconfig /all may help.

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

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.

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.
