You receive a “HTTP could not register URL…” error when sending a form to a tablet.
To fix this error we need to run 2 commands in command prompt (admin) on the workstation that’s trying to send the form.
Open Command Prompt as admin and run these 2 command lines:
netsh http add urlacl url=http://+:6667/TempUri1/ user=Everyone
netsh http add urlacl url=http://+:6667/ user=Everyone
You will see a message confirming URL reservation successfully added.
