DNS and Exchange issues



Marina, Susan, et al, please help! From my previous thread (9/16/05, 12:51
GMT, subject line "Internet Connection issue out of the blue!", I can't seem
to keep the problem fixed and need advice...

Short setup summary: Dell dual-processor PowerEdge server, SBS2K3, 2 nics,
no ISA, cable modem (comcast). The server is in my house, because it was
the best/fastest internet connection I had available and where we run the
business out of. Therefore, we need to use the comcast email address as our
authentication to send email.

Automatic updates installed the Exchange patch 888619 on Friday 9/16/05 at
3:00 am and then all hell broke loose. Exchange stopped sending or
receiving email. What Susan told me are DNS issues cropped up, with the
Comcast DNS servers sneaking into my ipconfig /all results.

Previously recommended to install hardware router between cable modem and
SBS box. Did that with a Linksys VPN router, but have too many ports that
needed to have traffic allowed. Problem is, I have email users that are
direct exchange, POP, and IMAP, need to allow websites (80 and 443), and
remote admin for myself since I'm not around the server much, Microsoft VPN
into the server and Cisco VPN to another office (external network but must
allow the traffic). Email, which I had cobbled back to working, stopped
again so I removed the router temporarily.

I'm trying to get this nailed down once and for all. I would like to put a
hardware router in between the SBS box and the internet connection, have the
websites, exchange, and remote admin working, and I'll figure the rest out
later.

Can anyone help me? I know I've hit my peter principle ceiling here and
don't know where to start. I'm thinking of removing the 888619 patch and
seeing what if anything that does for me. Any other ideas?

Skip Shean
