Same HOSTS file on all machines?If you PING your DNS service by IP address from the affected machine is it still noticeably slower than one of the working machines?Do you have an internal server for DNS or just public servers?What kind of firewall are you behind? SonicWall? SnapGear? Something like that? -B- http://www.officeforlawyers.com Author: The Lawyer's Guide to Microsoft Outlook

Ping by by ip address gives the same round trip time for all machines. Ping by any domain name gives 8 to as much as 30 seconds latency before printing the first line of output on the affected machine and 0 seconds on the working machines, but the latency does not change the round trip time and it is the same as ping by IP address.Have been given several different directions for DNS, "Use your ISP DNS" versus "Use your router gateway address" versus "Use 4.2.2.1" The affected machine had been perfectly happy for lots of years using the second of those. When this problem started I thought something in that might have broken so I switched that to 4.2.2.1 like the unaffected. No change.Firewall turned on in the SMC Barricade 7004VBR and NIS firewall running on each machine, all identical installs a week or so ago.HOSTS files on most of the unaffected machines is ~250kbytes dated 9/2008 which probably means that was put in place by NIS then, filled with scum domains. HOSTS file on the affected machine is 3 dozen lines and has a newer date, unknown source or history. So I copied a HOSTS from unaffected to affected, rebooted. No change.
