Outlook Express - Port 25/110 blocked 1

[vbjock]

Our lan has a fileserver (window 2003) and 7 workstations (XP Pro). When using MS Outlook/OE, on my workstation, my email send/receive fails. Error message: Protocol SMTP, Port 25, Secure(SSL): NO. Socket Error: 10061, Err no.0X800CCC0E. Same for POP3, Port: 110. Talked to our ISP and Dell. They said port 25/110 are being blocked by either the Firewall or Anti-virus (Norton). Using the Fileserver, I am mostly successful, although from time to time, I also get an error message that I need to receive before I can send. We have a primary router (black box) provided by Covad and a secondary router (Linksys) that all the workstations connect to. I believe the fileserver uses a static IP address for the gateway. The workstations are dynamic by default (DHCP). The fellow who set our equipment (Dell) is no longer around. No problem running IE, though. Any suggestions? Thanks.

firewall (hardware or software), or AV (software).

Many businesses will block those ports from all sources other than the server.

I will take a physical look if any hardware is involved by way of firewall. I will also see if I can disable the Windows firewall on both the server and the workstation temporarily together with the AV software and see if the problem goes away. The fellow who set up the lan mentioned sometime ago that the Linksys router goes thru the primary router to hide the various workstations from the outside world. Linksys does the job of port forwarding if needed. Again, this may be enough to make OE not work.
Thanks

Went to the site and found out they were using expired Norton AV. Uninstalled the AV and deleted existing emails/accounts and reinstalled the email accounts again. Problem went away. When I reinstalled the AV, it said I had 1 day left, etc. I instructed the office manager to renew the AV.
Thanks for the tip.
