Office Network Problem

[amar]

Hi all

I have a very strange problem that I have not been able to correct...I have an office network with 8 computers. We can access every internet site with no problem except the company website. This problem also continues into our outlook. We cannot use outlook to check our work email which also uses the same domain as the company website. From computers outside of the office we can access our website and webmail fine.

Anyone have any ideas what would be causing this problem only on the eight computers in my office?

Are they using a common DNS server? That would be one of the possible common points of failure there. When you do a DNS lookup from those servers are they returning the correct IP?
