Hi All, It seems apparent that it's time to upgrade our server. We have an NT 4.0 server with MS Proxy 2.0 that works like a charm, except now I have an XP Pro client that I cannot send or receive mail from. I suspect it might be due to the WSP client on the system. The system works with the proxy server for web access just fine but it will not send or receive pop3 mail from Express or Eudora. Any suggestions as to what might be happening are welcomed and as always thanks in advance for the help. Bob Owens Technology Coordinator Addison NW Supervisory Union 15 N.
