Have a home LAN with a couple of Win XP's and a linux mail server. Recently added a desktop which for some reason cannot have its IP address resolved by the server. All clients have static ip addresses(192.168.0.50-56) but the desktop has exactly same configurations as other clients but always has my EXTERNAL IP address resolved whenever logging on for mail.
postfix/smtpd: Anonymous TLS connection established from unknown[121.xx.xxx.xx]: TLSv1 with cipher DHE-RSA-AES256-SHA (256/256 bits)
Nov 23 17:53:21 mail postfix/smtpd: 0D70D62B: client=unknown[121.xx.xxx.xx], sasl_method=PLAIN, sasl_username=xxx
while other clients will have ip addresses resolved as per normal.
Using a Linksys wmp54G pci wireless card and router is a 3com 3CRWDR101A
My server firewall is fine and win xp has all the same settings
Anyone has an idea??
