Hello all.

This morning one of my applications stopped working.

The error message I'm getting if this one:

System.Net.Sockets.SocketException was unhandled
Message="The handle is invalid"

I'm suspecting one or more of these windows updates to cause the
problem:
kb935839
kb929123
kb935840

Has anybody else seen this?

I have initiated a support request with MS and I'll reply to myself
with the solution to this problem.


Cheers

If you suspect the updates, then the first thing to try is uninstalling
the updates. With some updates, you can just uninstall them directly.
With others, you may have to use System Restore to go back to a checkpoint
prior to installation.

Either way, it doesn't make sense to _assume_ it's the updates. You
should have a direct way of testing that, and so that's the first thing
you should do.

Also, unless all of your network-enabled applications have stopped
working, it would surprise me if this was actually related to the
updates. At the very least, if it is related to the updates, there is
something unique about your program that is causing it to fail when no
other application does. So the other thing for you to start looking into
is what non-standard way are you using the networking API that causes your
application to fail when no other application does.

I have had similar problems the last few days, since the updates were
released. I'm very interested in reading about any kind of progress
that you make.

I have a server/client remoting application, where the client
successfully calls the server, but when the server tries to call the
client back it fails after about 60 seconds. On some machines that are
updated however, the application still works. So if the updates are
causing any problem, it's probably in combination with something else.
Confusing...
