In Foxboro's defense, I wonder if anyone can really do high-quality
testing of a large application suite on a complex OS that is updated
frequently (like Windows), and whose progenitor (i.e., Microsoft) has no
problem making drastic changes to it and then telling users and
application providers that their problems exist because they didn't move
to the new version fast enough. David is right; the XP SP2 problem is
quite widespread.
Solaris is also a complex OS, but it doesn't change as rapidly, and I
don't think the API has undergone the drastic changes that Windows' has.
And, of course, it's not so much a target.
Possible solutions?
1) use a simpler, more purpose-built OS (e.g., QNX, VxWorks).
2) use something like Java to try and insulate you somewhat from the
underlying OS. At least you can write a decent regression test for your
VM, and once that passes on the new OS release, you are fairly confident
that your apps will work. Any other issues, like security holes in the
base OS, are still there, however.
I see some things that could make one of these two routes more palatable
(Foxboro's plan to put an OPC client on an FBM, for example). And
third-party apps can be run off-platform, using some well-defined, secure
connection method to talk to the DCS.

I don't think that it is a windows specific problem. All these Software
Application Provider (like Foxboro) underestimate the amount of time and
money to support monthly changed operating systems (windows and linux
too).
These Software Application Provider (like Foxboro) were fascinated by
the possibilities to realize very quick integrated solutions (on windows
and MS promotes that). But these quick solutions are not maintanable and
a change in the underlying os kills this application.
A Software Application Provider avoids a lot of problems by choosing a
platform/os that doesn't changes to much. But I can't see a thing like
that in the near future because all these hardware and software things
were changed daily.=20
I'm wondering that Foxboro has thrown his unix know how away and
switched over to windows.=20
