Web page with lots of information causes network to fail

Web page with lots of information causes network to fail ...

When I go to a web page with a lot of information, then my network fails ..
basically, the network activity stalls, the web page does not fully load and
my network drives fail ... the best way to resolve is for me to manually go
and disable the network connection and enable again (which is frustrating).

Any ideas what could be causing this?

I browse the exact same web pages on other computers and they work perfectly
fine.

One other issues that might be related ... when I use Microsoft Remote
Desktop Connection ... the connection also fails on the same web pages ...
but interestingly it also fails when I view email (in Outlook) that are HTML
and have a lot of content/pictures in them.

Any ideas?

Thanks in advance for any help.
