I cannot reach one of my vendors web sites. I can access the site from home, my boss can access from his home. But, from the office it does not work using the domain name. Using the IP address in place of the domain name does work. From these facts, it seems that I have a DNS problem at my work location. The DNS is obviously not completely dysfunctional as I am able to get to any other domain name that I have tried including some that could not possibly be locally cached. My environment is a windows network with a Server 2003 Standard server acting as the domain controller and hosting the DNS for my intranet. The problem has been going on for two days.
As a developer, I understand the basic concepts of DNS, but am not well versed in the specifics. Nor am I much of an administrator, but unfortunately, I am all we have.
Where do I start?
