I have all the Computer Browers services turned off except on one machine... my domain server.   I've got three workgroup computers hooked up now, along with three domain computers.   All workgroup computers can see and access data on the domain machine.   And they all see the other workgroup machines, but cannot access the data on them... can't expand the computer node to see the drives.

Now... I am trying to share full drives... not my C: drive, but the data and project drives (D: and E:).   Ed, you are saying that's a problem?  That I need to share explicit folders on those drives?   I'll test that.
