For starters I am not sure that I picked the right zone to post this question. In most cases we are using firefox as the browser to access this application. On the computers that this will not work, opening PowerSchool with the Safari browser gets the same results. The application is a student information system and when you start the gradebook off of the PowerSchool application you open a pop up menu that says.
LaunchGradeBook.jnlp
which is a: Java Web Start file
What should Firefox do with this file?
The selection that is default is Open with -- Java Web Start
I have checked the permissions on Java against the permissions on a computer that works. I couldn't find anything different there.
After that and reading you instruction I am going to tell you I am really lost. I do not know how to reinstall a root certificate chain.. I have no clue if this is a commercial CA cert, internal CA issued or self-signed. In other words I am way over my head on this one and so far the techs at PowerSchool are telling us that a) this is not their problem b) They do not support PowerSchool on Snow leopard.
I would try some of your suggestions if you would give me more directions on how to do that.
THanks

That's odd if it happened to a whole environment like that. Could try checking permissions on the root cert (although I don't know why they would have changed, just a sanity check here really) and reinstalling the root certificate chain.
Was this a commercial CA cert, internal CA issued, or self-signed cert?
Sorry, I'm not familiar with that app right offhand - is this a browser application? If so what browser are you using (firefox, other)? check the browser's cert store under 'signers', 'CA certs', 'Issuers', 'Root Certficates', etc. depending on app. Compare the thumbprint/fingerprint to make sure it is the same version of the cert as is being served. Maybe an old cert was there and warnings ignored before as a workaround, and settings got reset by the upgrade or something - pure hypothesis here.
