Application exception - External Component has thrown an exception

[AndrewBuchan]

Hello.

I develop an internal system used to manage our customers. We have 2 offices who use this software every day.

Every now and again, users of one of the offices run into an error which reads:

System.Runtime.InteropServices.SEHException: External component has thrown an exception.

This only happens for one of our offices, and not across the board (I had one user inform me of this exception today, but others are not having any trouble).

The office which is experiencing this remotely connects to one of our servers as we are the headquarters of the company, whereas we login directly to our domain controller.

Furthermore, the event which causes this error is not always the same and the code in the underlying event does not use any external component.

Any ideas?

That's very strange. I was going to suggest a bunch of potential debug steps but I googled the error and found this...

http://social.msdn.microsoft.com/for...-b7e3bf4cc03c/

Near the bottom there, they recommend restarting the IIS service. Another person confirmed that this resolved the problem for them. It might be worth a try?

I might also recommend trying to put a try/catch around your whole program so you can maybe log more information coming from this exception. Specifically where in code it happened and if there's any more exception information.

That MSDN page seems to suggest it might not happen in the same place, so it might give you some ideas.

Good luck!
