I've had an ASP.NET site up and running for a about a year. It's mostly used by people in my internal network, but access is allowed from anywhere with a web connection via HTTPS. For the most part, this works fine, I don't hear any complaints. However,
every couple of months, I hear reports that my external users cannot access the site. I check and it works fine for me internally, but if I do a webex to someone elses computer outside my network I am unable to get the page to load.
I've checked obvious things, DNS is still pointing to the correct IP address, I can pull up other web sites on the computer (and it usually affects everyone external). The network firewall has not had any recent changes.
I have tried restarting IIS but that doesn't resolve it. The only thing that seems to fix it is to completely reboot the server.
Anyone have any idea what might be causing this? What kind of logs could I look through to check for issues?
Windows Server 2008 R2

When it's not loading, does it show up any error?

suggest doing some traceroutes from problem computer while on webex from the commandline to server, and also from your own system to the server and compare the paths, I would suspect thatyou have intermitent network issues which affect the users outside
the local network you are accing through, tracert is a good first pass at figuring out where your network sees the server and you can compare it to your path to see if it is trying to get to the same place.
