I had to reinstall Windows XP Profressional and Outlook 2003 after a disk
crash. I'm using Windows firewall and Norton anti-virus. When launching
Outlook for the first time I am unable to connec to my corporate exchange
server. It times out Configuring Outlook Account. It then indicates it
cannot connect to the server. I did not have this problem before the crash.
I have confirmed the Exchange server address. A tech admin indicated my ISP
(Comcast cable) could be blocking the exhcange server port, but I did not
have any problems pre-crash. Any ideas? Thanks
 
Exchange Server ports, plural; there are MANY ports which must be open on
both Comcast and whatever firewall this Exchange Server sits behind. It is,
therefore, highly unlikely that you were making a direct connection with
this Exchange Server via Comcast unless you either created a VPN tunnel into
your corporate network, or you had Outlook 2003 configured to do RPC over
HTTP:

You could also have been using POP3 or IMAP4 instead of the native Exchange
Server mode; these would use either port 110 or 143 (which usually are not
blocked by ISPs). If so, post back and we'll go into more detail.
