odd 'can't find server' messages

[Cloudgazer]

We have 3 macs in our office (2 Imacs and 1 dual PowerMac).
We are all on the same network, all have the same settings,
but the Powermac keeps getting errors when surfing the net using both Safari and Explorer (Can't find server, page not available).
This doesn't happen on all sites, and the imcas don't have any issues accessing these sites.

I thought the problem might be that the PowerMac is running 10.3.7, but then so is one of the iMacs.

Any suggestions?

99% of the time this is a DNS issue.

Go into your router or other computer and get the DNS addresses that your network uses. Go into network preferenced and add the DNS numbers into the DNS box and hit "apply".
