Tiger, Vpn & Web Based Applications


I have recently upgraded from Panther to Tiger since this I am unable to connect to a web based program to create job forms from home which we have running on a PC at work. when I go to the web address Safari says "Safari can't find the server." This was never a problem when I had 10.3 installed. I have done all the updates but this has not helped. I also have a VPN connection for work this will connect but will not find any of the work servers, again this wasn't an issue with Panther. Any ideas.
