I'm attempting to serve up Java applications via JNLP. It's MicroSoft Server 2008 IIS, with the ".jnlp application/x-java-jnlp-file" mime-type added. The application launches fine from Solaris/FireFox clients. However, when a JNLP launch is attempted from a Windows Vista client, the JNLP file opens in Wordpad! JNLP launches on the same client, from other servers launch the application just fine. Apparently one of us has missed a step somewhere in the server setup. Anyone got an idea what's missing?

Ugh. Turns out to just be broken JRE plug-ins on the boxes I was using for testing. Nevermind.
