To help answer this, I'll need a little more info.  If I understand you 
correctly, the "192.168..." NICs on both of your LTSP servers (you don't 
specify this, so I'm by necessity making an assumption here) are your "eth0" 
interfaces for talking to your thin clients.

Furthermore, both of these eth0 interfaces are now on the 8-port Gig-E switch.  
Additionally, you have this newly acquired, SCSI-disk-equipped file server 
that is on this same Gig-E switch, and all of this constitutes a single 
broadcast domain which houses only the 192.168.x.x subnet.

BTW, which specific 192.168.x.x subnet are you using--is it 192.168.251.0, 
192.168.33.160, 192.168.2.128, etc?  I don't see that specified.  And what is 
the subnet mask?

Finally, you have this 8-port Gig-E switch uplinked to a Gig-E port on the two 
switches in the lab (another, separate room).

Is all of this correct, or am I misunderstanding something here.
