At the start of the week I noticed that I could not connect to the Internet on several of my Dell Poweredge 830 servers which run Server 2003, it just trys to connect and then a message states that the page cannot be displayed. I could connect to the Internet before. All of the other servers (which are NOT PE 830) can connect with no issues. I can ping all internal devices including the firewall and external devices by IP and their DNS names.
It seems that it is connected to the network fine and has all the correct DNS and default gateway settings but It seems that I just cannot connect? I've been looking into it for several days now with no joy.
In addition to this I have AVG installed on all servers and workstations and updates are not getting through because of this issue. I have updated and restarted the servers (to install them) twice over the past week, could It be a security update for the operating system or IE?
