The requested resource is in use. (Exception from HRESULT:
0x800700AA)

Hi,

I have a thin windows client in the front end that talks to ASP.NET web services
on the backend. Currently this application is going under load testing. When we
have 2-3 users simultaneous using the application the users are complaining that
they are seeing this error often. This error is not reproducable as it happen
randomly. Can anybody who has seen this error or delt with it suggest what could
be wrong.

On the IIS the ASP.NET site is on it own AppPool. I have used the default IIS
settings for the AppPool. The server is a single-core windows 2003 web edition
with 1/2 a gig of RAM on it. I look forward to replies on this

Thanks

At what point in the client code is this error hit?  Any relevant messages in
the IIS log or server Event logs?

There is no info in either IIS logs nor Event logs. No warnings, nothing. In the
IIS logs once in a while I am seeing a "64" for sc-win32-status. Can
you (if u know) explain what this means? (that's the last column in IIS logs)

I am not sure whether I totally understand by this "at what point in the
client code is this error hit?". 

Most of these errors are popping in a script window with the title
"Internet Explorer Script Error", an error occured in the script on
this page and inside the error, I am seeing this message "The requested
resource is in use. (Exception ...)"

It is happening randomly and usually when 2-3 users on using the application.
The only other thing I wanted to mention was, on the webbrowser control, the
propoerty ScriptErrorsSuppressed is set to "True". Does the
webbrowsercontrol use any extrenal COM components (since there is HRESULT)?

Thanks for ur help

I found out that 64 means "the specified network name is no longer
available",. Also I am seeing Timer_ConnectionIdle in the HTTPErr logs in
the server, unfortunately these are not happening at the same time as the errors
pop-up.

your client-side code and really nothing with IIS.
