I have recently upgraded our internal network to a brand new Windows server 2019 with all the latest updates and a fresh Active Directory.
Since doing that none of the computers on the internal network can access our company webiste www.alcom-it.co.uk
Have tested in Edge, Chrome and Firefox but all 3 just timeout and give this error...
This site can’t be reached
www.alcom-it.co.uk took too long to respond.
Checking the connection
Checking the proxy and the firewall
Running Windows Network Diagnostics
Tearing my hair out now so any suggestions would be most welcome.
