I've helped a company redesign their website, transfer it from a different host service and set up their handful of emails.

The email settings they had for their previous host service were the same as the ones for Vodahost, so all I had to do was change the dns nameserver. All the emails worked fine except for 1 -- r.nunez@companyx.com. Using Outlook and XP.

It works fine on a different computer, but not the one he uses. Any ideas? Could there be a fire wall setting or something specific to this computer I should look for? I'm going over to check it out tomorrow. All the computers are on the same small office network, same ISP, etc.

Any help would be appreciated.

For anyone interested. I solved the mystery. The one computer had specific DNS addresses supplied for it's TCP/IP Settings under the Network connection that were different from the other networked computers. Something to check....
