We have a Windows SBS 2003 SP1 server that we need to access remotely. The key resource apart from email is a Sharepoint site (set up in the default companyweb site) which we access via Remote Web Workplace (https://sbs1.domainname.com/remote
. All appropriate ports (80, 443, 444, 4125) are open on our firewall. No fancy stuff (ISA Server, VPNs etc) installed.
Everything works fine on a normal home internet connection, but when users try and access from a particular client’s site (ie behind their firewall etc), Sharepoint isn’t accessible.
Users can login and get as far as the RWW main page, access “Read my company e-mail” etc, but when they try to access the SharePoint site from “Use my company's internal Web site” – they just get “this page contains secure and non secure items” then “Page cannot be displayed”. It should be challenging them to authenticate. I assume the client’s firewall is blocking a port that’s needed (would that be port 444?).
Getting the client to change their firewall settings is a non-starter (and there are bound to be other sites that we visit with the same issues), so how can I get them access to Sharepoint?
One thing I should say – they tend to use client’ company’s computers when on-site, so we can’t install any software eg VPN.
