host:port fail, security issue?

[Alberto]

Hi,
I`m hosting my web server in a machine listening to the 88 port (cant unse 80)
Some users, from some locations, cant connect to it, they receive" Internet Explorer cannot show the page..." error
Is there something they can change in their explorers or is a router filter?
Thanks
Alberto

Most likely a router or firewall blocking them. This is not uncommon. I'm not aware of any port-specific blocks in IE itself - but of course there may be there. Can the same users browse from a different browser ok?

Cheers
