Because Netscape Navigator and Internet Explorer do not support the Java mechanism for applet signing, the administration GUI cannot get access to your system's local resources (browser security mechanisms prevent this type of access.)
The operations that require access to your local system resources are:
Loading certificates from a diskette
Backing up all policies
Restoring all policies
Saving log files
Loading jar signatures
If you do not need to perform any of these operations, you can use any of the supported browsers without local file access. To work around local access limitations you can use one of the following options:
Use the Java plug-in.
Use the HotJava browser, version 1.1.
