On hitting refresh, they get the page - no problems. If I wait a while and try again, I get the same problem. The problem appears to be something in the initial communication with the web server. Using tcpdump, I can see that the PC connects to the web server and sends the GET request, but the server closes the connection abruptly. Comparing that flow to a normal session, I see that there are some extra packets between the initial SYN and the sending of the GET phrase that do not exist during a successful session. I'm running 5.4-STABLE FreeBSD 5.4-STABLE #0: Thu Aug 18 (built from the stable source as of that day). I'm using apache 1.3.34. I was on 1.3.33 and rebuilt the port to see if that was the problem. I'm not sure if this is an apache problem or a FreeBSD problem. Any suggestions on further troubleshooting or known issues? Thank you! Jerry
