.Nco 3.0 is compatible with Windows Server 2008 R2 ??

[Former Member]

Hi All,

I am using .Nco 3.0 connector for one of our .net project. I deployed the site at 2 different servers 1 is Windows Server 2003 and 2nd is Windows Server 2008 R2. I am facing problem of Sessioon timeout (All other IIS and .NET application settings are done) on Windows Server 2008 R2 which is working properly on Windows Server 2003.

As I am getting below exdception for Event details

StackTrace: at System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource resource)

at System.Collections.Generic.Dictionary`2.KeyCollection.Enumerator.MoveNext()

at SAP.Middleware.Connector.RfcSessionManager.UpdateSessions(Object state)

Please guide me for same

I assume this is a website, yes? 

1. Check the Application pool user.  Instead of using Application Pool Identity, try Network User.
2. Is the server 64bit?  If so, check Enable 32-bit application on the application pool advanced settings.
3. What kind of authentication is enabled?

Right dear..its website..

1.I have changed Application Pool Identity to NetwrokService.

2. Server is 64 bit. Enabled 32 bit application.

3.Forms authentication enabled.

So you mean to say this error is not coming due to .Nco 3.0 due to some IIS settings??

Thanks for reply...
