That's not making any sense..
old machine> \\new-machine\snmptable -m ...
gives the "bad" format output, same as

new-machine> snmptable -m ...
and
new machine> \\old-machine\snmptable -m ...

Is that right?

A bit drastic, but you could always delete the NET-SNMP directory on
the new machine & then copy it over from the old machine.  Less
intrusive would be to compare the directories from the two machines
and copy old -> new to remove any differences.  I like WinMerge
(http://winmerge.org/) for that, but I'm sure there's lots of
different programs for that.

I thought there was an snmp program option for showing which mib files
were loaded in what order, but I'm not finding it now :(    Some
combination of snmptable -Pe -PR -Pw might give you a hint as to
what's different between the two machines.

Do you have a .bat file that you run to initialize the environment or
is everything coming from the env. variables and/or registry?

Comparing the output from "set" on the two machines might show what's different.

I understand.  I'd be doing the same thing in your place :)
