Appfabric Dashboard: Filestream will not open

Question

Hello,
We get an error when we want to retrieve the information ("Gathering Data..") in the appfabric dashboard:
“Filestream will not open Win32 devices such as disk partitions and tape drives.Avoid use of \\.\ in the path.”
In the Eventviewer shows only this Error:
“This cmdlet can be executed only on resources running in a 4.0 application pool.  Error ID: ApplicationRuntimeVersionNotSupported”
On this server there are  some other application pools with Framework 2.0.
Appfabric  is installed on a server which is running small business server 2008  and IIS 7.0.
The ASStagingTable is empty and the  AswcfEventsTable is filled with events.
File based tracing and message logging is working.
First there were more Errors:
Filename: \\?\C:\Program Files\Microsoft\Exchange Server\ClientAccess\Autodiscover\web.config
Line number 515
Error: Unrecognized element ‘compilers’
Then we commented this node in the web config out.And this error disappears.Maybe the problem is in exchange or ASP.net configuration?
Thanks in advance,

This is a confusing error because you are probably not invoking Powershell yourself right?

Some of the UI functionality calls Powershell behind the scenes. Is it possible your site that is using AppFabric does not have its app pool marked for .NET 4.0?

Or is it possible one of your websites refers to a UNC network path like \\servername rather than a local path?

Thanks,
