I've been playing with new URL monikers in Windows for a utility I'm working on. When I run the new URL from Start > Run, it just runs. If I send the URL to myself via Notes or enter it into the IE address bar, I get a window which says:

"Do you want to allow this website to open a program on your computer?"

Program: UrlMonikerTest1

Address:  urltest://ticket?param1=42&param2=Derf

[CheckBox] Always ask before opening this type of address

                                      [Button]  Allow  [Button]  Cancel


Allowing web content to open a program can be useful, but it can
potentially harm your computer.  Do not allow it unless you trust
the source of the content.  What's the risk?

Given that the utility will only run on internal machines to which it will be deployed using SCCM and to which I can apply Group Policy, can I disable this message for this application/URL moniker alone?

The clients are currently XP. They will be Win7 at some point. We don't have to consider Vista.
