System.ComponentModel.Win32Exception (0x80004005): The system cannot find the path specified

I am trying to generate a report by using SQL Server 2008 R2 File Stream and WCF Service. I am able to generate reports if the service is hosted in the same server which database is located i.e. Database and service is hosted in the same server.

If I hosted the service in different server I am getting the "System.ComponentModel.Win32Exception (0x80004005): The system cannot find the path specified" exception. I have given all the necessary permissions to the SQL FileStream share location like IIS_User, Everyone etc and I am able to access the share path from the new server also. Still getting the same error.

When I am checking EventViewer in server it is throwing, System can not find the specified path \\Machine_Name\FolderName\v1\DBNAme\dbo\TableName\ColumName\06E9456C-A090-24Ge-9C35-25FDG54FE78RR25

\\Machine_Name\FolderName\ this one is SQL FileStream share path.

Please help me to get out this.

It seems that the issues like this are related to any of the following need to be looked at:

1. firewall settings from the web server to the database server.

2. connection string errors.

3. enable the appropriate protocol pipes/ tcp-ip.

You could refer to the following article to troubleshoot Connecting to the SQL Server Database Engine:

In my opinion, this is likely to be caused by a connection string error, you need to check your connection string.
