Hi all,

I have a strange problem.
On a network running SBS, some computers can't access some websites.

The server can access everything, fine.
User PCs can access some websites. Only some.
Others, when I type in "www.overclockers.co.uk", it brings up Bing's search results for www.overclockers.co.uk (so it's on the net, but won't go to the actual site)

Including http:// in the address then just takes it to a

"Internet Explorer Cannot Display The Webpage"

This problem can be caused by a variety of issues, including:

•Internet connectivity has been lost.
•The website is temporarily unavailable.
•The Domain Name Server (DNS) is not reachable.
•The Domain Name Server (DNS) does not have a listing for the website's domain.
•There might be a typing error in the address.
•If this is an HTTPS (secure) address, click Tools, click Internet Options, click Advanced, and check to be sure the SSL and TLS protocols are enabled under the security section
Click to expand...

Clicking "diagnose problems", brings up a window that says
"Contact your network administrator or Internet Service Provider The DNS server may be experiencing problems.."

My server is the DNS server, but that one works fine....

Any ideas????
 
On the client machines that are acting funny, do an >ipconfig /all at the command prompt and see if the server is actually listed as the DNS. Are you using a web proxy at all?
 
No web proxy
All machines are pointing at the server for the DNS.

I've cleared the DNS cache on the server, and that seems to have fixed it.
Which is good, but i don't suppose you'd have any idea why it messed up in the first place?
