Hi Team

I'm having trouble finding a tool to assist with troubleshooting access to specific web sites.  For example I can access a supplier's public web site in the UK, but a soon as I go to login to their secure web site (which uses a different domain name) the 'connection is reset', but it can be accessed fine from a connection with a different ISP.  And today a client cannot login to Westpac's online banking for no good reason from their DSL connection but it is fine from ours.

I've been Googleing but have not found a tool that can give me an idea of what is preventing the connection and page display.

Any suggestions welcome.  I was hoping for something a little more user-friendly than Wireshark.

Thanks in advance,

First thing to check would be DNS - are the the DNS names resolving to the same IP addresses across ISPs?
