all three machines MUST point to the shared net file using the EXACT SAME 
path/mapping, including drive letter

all three machines MUST point to any shared data using the EXACT SAME 
path/mapping, including drive letter

they can't just resolve to the same place, they must be addressed exactly 
the same way

Thanks for the reply Steven
In the simplest test I open a table (49 records,22 fields)on each
machine: 1 server/workstation, 2 workstations

I make a change to one field on a computer and in my mind that should
update that same field on the other two machines. It does, sometimes. I
found that on each machine switching to Windows Explorer and under
"View" I click "Refresh"  then after awhile the tables on all the
machines would update without switching to W-Explorer, as expected.

The server/workstation (call it mach #1) has drive E mapped to itself as
drive "I". The other 2 machines have mach #1's drive "E" mapped as
networked drives:

Mach #1 Mach#2 & #3
E   I (mapped to mach#1 E)
I (mapped to E)

I have confirmed that Mach#1 is the MasterBrowser, if that makes a
difference
