Appletviewer, javac, java, etc (tools in the /bin directory) don't accept UNC pathnames as arguments. (UNC is a naming convention used by Win95 and WinNT for specifying paths without specifying a mapped drive letter...i.e. instead of saying e:\jse\files\target.java, you would specify in UNC format... \\jse\files\target.java. Currently,

javac e:\jse\files\target.java //this works

javac \\jse\files\target.java //this doesn't work

This functionality should be added in order to provide full support for the Win32 platform. This is also needed for our test efforts. We are currently using Solstice PCNFS client (which uses UNC names) to run automated tests over the network
