Website access problems for Networked PCs

[philb101]

4 x PCs all on same Network & in same Workgroup all XP Pro SP2, fully updated
All using IE7, not certain which version of Adobe all are using

When accessing a certain website, which after logging in & making selection of product to view displays product in pdf format

1 PC can access & view information with no problem
1 PC can access & view information after being prompted to download file &
2 PCs will not even access the website with exactly the same URL typed in the Address Bar

All the PCs sit behind a Firewall which only has a global policy so there is no PC selectivity re: viewing websites

Any thoughts on how to enable all these PCs to view this website without problem would be appreciated

Thanks for all help

Ping the website first, than diagnose application layer problems like firewall, anti-virus and proxy setting (web browser).

yeah, definately check out DNS and Proxy settings, ping first.
