Cannot mount volume

[Keith Clark]

I am running Nautilus on my server via ssh and I cannot mount any
volumes with it.  I get the following error and I'm not sure where my
problem lies:

A security policy in place prevents this sender from sending this
message to this recipient, see message bus configuration file (rejected
message had interface "org.freedesktop.Hal.Device.Volume" member "Mount"
error name "(unset)" destination "org.freedesktop.Hal")

I have no idea what this means!
