Aliased network volumes pull up the wrong volume

[bunner bob]

We have an Iomega NAS box with three volumes on it. I mounted each of these volumes and created an alias for each, which I put in my dock.

Everything worked fine for a while, but now all the aliases pull up the same volume. It's like my Mac is fixing on the first volume mounted (say, after a restart), and any subsequent mounts always pull up that volume. Even if I go home and come back the next day, if I click on the Drive B alias it still mounts Drive A (if that's the one it happens to currently be "stuck on"). I can restart and then if I mount Drive B, subsequent clicks on Drive A or C will still pull up a window with B. I tried recreating the aliases but that didn't seem to fix it.

I'm left with hitting Command-K to select the server, then choosing the volume I want from the list (which works correctly). Not the end of the world but not what I am hoping for.

Any idea what might have become messed up to make this happen?
