Hi Lee,
I didnt express my thoughts very well on that.
Basically, the short version is the problem stays with the machine (\\new)
housing the support files minus the executable.
When I remotely execute the snmptable.exe that resides on the machine
that gives bad results - from the machine that gives good results - the
results are good
and vise-versa
In other words, the problem appears to lie in the support files or some
other machine configuration, not the .exe itself.
I will try the idea of delete all of the files from the 'malfunctioning'
machine, and copying them from the 'functioning machine and see what that
gives and let you know the results.
I was hoping for less of a shotgun approach, but I've already done a lot
of file compares, etc and haven't found anything.
Thanks
keith

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?
> Any other ideas, or ideas on how I can track this down?
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 :)
