Thanks Jim,

I downloaded Spiceworks and WireShark.

Hi Bill:

I was scared you would ask that question. It is not because there is any 
difficulty in finding application that can do the task but there are just so 
many products that each fill a certain category. None of them is perfect at 
any price. OTOH, there are some excellent inexpensive and free apps out 
there. Add to that, there is a whole series of specialty niche products to 
do a specific function on a network...

Here are a few very fine products:
http://ganglia.info/

https://www.nagios.org/ (runs on windows)

http://www.observium.org/ and hardware/software supported: 
http://www.observium.org/supported_devices/

https://www.spiceworks.com/free-network-monitoring-management-software/ 
(runs on Windows)

http://www.zabbix.com/

(* most of the above run on windows via webUI and client components)

The big monitoring software packages can cost upwards of hundreds of 
thousands. The packages listed here are not all free by fairly inexpensive, 
have community editions, can run from a browser, off a server, off a Cloud 
droplet, have a host of features and support a variety of operating systems 
and can support up to 10K devices. It all depends on what you need and what 
you can adapt to your network. I have only seen two of the products in the 
above list running but have heard of them all.

I have a mixed network which I play with. :-) It has servers and desktops 
hosting Microsoft and Linux products and they all seem to work together. I 
have noticed, in the industry, now a days, that most desktop machines are 
Windows and most server/internet/NAS machines are Linux. Protocols are 
fairly standard so in many cases integration is not that difficult.

Here is another list of 20 monitoring tools that might be better suited to 
Windows. I have not used many of them but they are supposed to be good but 
their range of functionality can be limited and specialized:

Of course for real down and dirty network protocol analyzer there is nothing 
like WireShark:

https://www.wireshark.org/ (runs on windows)

I hope this helps.
Jim

Hi Jim,

Could you recommend one or two free ones or even inexpensive ones for
Windows?

Thanks

Bill

Just a note: There are a number of good monitoring programs out there. Some
are free and some are very reasonably priced.

These applications can be used for managing a network's performance. From
flaky network cards, hubs, routers and switches to data transfer rates from
one computer to another through various programs. If there is any network
congestion a good monitoring system should be able to isolate the problem.

The problem with this error is that so many things can cause it, and yes,
it's the network in some way.  JET works fine over a solid LAN with little
issue (and note LAN, not a WAN - can't tell you how many people try to run
it over a WAN, which it was never designed for).   Problem is, JET will
complain loudly long before other apps do, so it usually gets blamed for the
problem.

Besides the wireless issue (high latency), also look for NIC cards that
have power management (go to sleep) and disable that.  Also disable any
diagnostic protocol they might have (card disconnects from the network, runs
its tests, then re-connects, which will drive JET nuts).

If your using mapped drives, be aware that windows has a built-in timeout
which needs to be disabled.

Also have them check that DB's are not being virus scanned on the stations
or servers.

And unlike the others, I don't believe going unbound is really a solution.
If your going to bother to do that, then you might as well not use Access.
And for most apps it would be a total re-write anyway.

A SQL Server backend though to replace JET is certainly an option and
usually not too much of a hill to climb.

Jim.

Hi Listers,

One of my clients is getting the following error:

"The expression After Update you entered as the event property setting
produced the following error: Your network access was interrupted"

Does anyone have any experience with this.  Surfing indicates that it is a
network issue rather than an Access one but I am working with another
company in charge of the hardware and am trying to give them leads.
