I have been contacted over the last couple of weeks by some existing customers who claim they cannot connect to the website(s) I host on a Win2003 Webserver.
Whenever they call me I jump straight onto a machine in the office and check to make sure I can view the website. I am able to view them and navigate throughout the site(s) without a problem using an office broadband connection we have. At the same time I am browsing the site(s)they are telling me they cannot connect from there locations in the UK.
I also have a mobile broadband USB that uses a different ISP to the the office broadband, this also connects at the same time without any issues.
Does anyone have any experience in what to check on the server that may be causing a problem?
IIS6 and Bind 9.6.1-P3
Thanks in advance.
