 Check to see if there is a Network Address Translation (NAT) between the client and server

In Windows, check to see if a Windows firewall is checking for your local connections:

Windows XP -> Control panel -> security -> Tab "Advanced" 

I think mostly there is an issue with that particular client machine with Firewall block.. if firewall is blocking than add that URL in to the exception list so then after it want create an issue
