AppCmd.exe Error :Failed to process input: The parameter 'Web' must begin with a / or - (HRESULT=80070057).

 Hi,

I am using Appcmd.exe to create Virtual directories, AppPools and applications. I am getting the following error in one of my environment where i have all the role services installed for IIS web server.

"%SystemRoot%\System32\InetSrv\Appcmd.exe" list app "Default Web Site"/TempAPP

I am running this command on a remote box using my exe which runs command on remote box. 

Here is the error i am getting upon executing the above command.

Failed to process input: The parameter 'Web' must begin with a / or - (HRESULT=80070057).

Failed to process input: The parameter 'Web' must begin with a / or - (HRESULT=80070057).

I tried creating the AppPool and listing AppPools and they worked with out any issue. 

I am not sure this is due to any role service added or removed from IIS.

Please share your suggestion.

Thanks,

Bharani
