Disable Java Security Warning using script/GPO

[netadmin]

We have a campus license for some web-based software that uses Java applets (the application is hosted offsite). Each time a user logs in to the application, they get a Java security warning that says:

 

Warning - Security

The application's digital signature cannot be verified.

Do you want to run the application?

 

Name: app

Publisher: unknown

 

Then there is a checkbox for "Always trust content from this publisher", followed by two buttons: "Run" and "Cancel"

 

Is there any way to prevent this message from appearing using either a logon script, GPO, or reg edit? The browser is IE7, client operating system is XP, server operating system is 2008.

 

I tried running the application and clicking "Always trust" when I made the master image, but unfortunately, when testing after deploying to all campus computers, it did not work.

 

Thanks.

In case anyone else ever runs into this problem, it looks like the following stops the security warning:

-Logon to a workstation using the default profile

-Login to web application and click "Always Trust"

-Logoff web application

-Restart workstation

-Copy Application Data\Sun folder to default profile
