error accessing a website (.NET Exception ?)

[Sanjiv123]

I am trying to access a page on a website

http://www.mbsgurus.com

From most computers it is fine and I have no problems but when I try it from a particular PC I get the error message detailed below.

By the way, the error only occurs when trying to access the page from one PC (running Windows 2000 Pro). All other PCs (same setup) have no problems:

Server Error in '/' Application.

Object reference not set to an instance of an object.
Description: An unhandled exception occurred during the execution of the
current web request. Please review the stack trace for more information
about the error and where it originated in the code.

Any ideas
Thanks in advance.
