Some people on our network can access our homepage, but others can't. I've checked routing, rights, our web filter and I cannot find anything that would cause this.
The people who host our website can't seem to find anything wrong on their end either.
Thanks for your replys. These PCs are frozen with Centurion Guard, so they have no antivirus installed.
We are all using the same Windows firewall as well as the firewall that's in our router.
