Prevent calling Web Service from being blocked

[Joe]

Is there anyway to register an application with the various systems (like
Windows firewall) to prevent the user from having to click the 'Allow
action' or similar that pops up from applications like Windows Firewall?

Is your firewall blocking requests to port 80?
Is it "their" firewall that is blocking the traffic?

If it is there's, they almost certainly have
to do this themselves for security purposes.
I can't imagine firewall software allowing
an automated registration process or
the software would be pointless.

Hi Joe,
Welcome to MSDN Newsgroup!

If we want to register an application in Windows Firewall, we could modify
the following registry to achieve this goal,
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\SharedAccess\Parameters\Fir
ewallPolicy\DomainProfile\AuthorizedApplications\List

I also browse an article from internet and hope it's helpful for you.
