ISA configuration block CD-rom access

I’ve setup ISA server 2000 on a W2k server.

After doing the ‘ISA Server Security Configuration wizard’ I’ve noticed that I can’t access the CD-rom drive of my server over the network.

* This W2k server is the only server on the network and theISA software is only needed for caching purpose.

Does anybody know a complete list of security policys where I can disable/enable the CD-rom access over the network?

Thanks in advance.
