I've got a PowerEdge R410 (BIOS 1.11) with iDRAC6 Enterprise (firmware 1.95).  I have the DRAC set up to share with LOM 1.  I can access the DRAC's web interface from another machine on the LOM 1 network, but can't access the DRAC web interface from Windows running on the same machine.

I was reading the documentation on iDRAC security and it says something about the DRAC network being isolated from the LOM network internally for security reasons, so perhaps this behavior is normal?
