All of our workstations running with IE6 to surf net. Recently all workstations were migrated to the new domain and we found that all workstations would not be able to access certain web page. Please note that when calling that web page, the page is performing a direct page. Proxy has not yet been implemented. We have performed a test by connecting one of our workstations directly to our communication link (before firewall) and the page can be accessed. We also performed a test using personal computer (not office computer) by plugging into the network environment and the page can not be accessed which the page can be accessible when using at home. Any one could give me advise where should I look to resolve this issue?
