Help understanding these errors

Hi there Mates,

I'm getting two types of error in service center e i don't know what is all about.

The errors are:

An error occurred while communicating with the remote host. The error code is 0x80070057.

I googled the error and it's possible the User closes the browser before the action/rendering is finished.

If that is the case, there is not much you can do about it.
Is it because of some bad-code, well, either there is a flaw in OS or your own code.

Hi Pedro,

We found that this problem is fairly common on Windows 2008 R2 64-bit, and most of the time its due a bug on the IHttpConnection::IsConnected method.

The following KB apply for the issue and a patch is also available for download:

We sucessfully installed on our DEV and QA systems w/o any problems and the error was gone.

If you're not running Win2008 R2 64bit you may want to check the following thread:

Hope it helps.

Hi Arley, and welcome back to our community forums!

How's everything going?

Thanks a lot for your tip, it'll definitely be useful to more people who bump into this kind of problem.

Looking forward to seeing you around more often, and good luck with your project :)

Hi Arley,

I've already find the solution a few time ago.

Just in case, the following errors are also frequently registered:
- 0x800704CD (An operation was attempted on a nonexistent network connection.)
- 0x800703E3 (The I/O operation has been aborted because of either a thread exit or an application request.)
