FIX: When you use an application that uses the FindFirstFile API to access an empty shared folder on a server, the API consumes all search handles on the server and then throws an "ERROR_NO_MORE_SEARCH_HANDLES" error

On a Windows Embedded CE 6.0 R2-based device, you run an application that uses the FindFirstFile API to access an empty shared folder on a server. When you do this, the API consumes all search handles on the server and then throws an "ERROR_NO_MORE_SEARCH_HANDLES" error. Additionally, if you added the File Directory Searches counter under the Server object in the performance monitor on the server, the counter reaches an unusually high number. For example, the counter reaches 2048 or more.

This problem occurs because the protocol stack in the FindFirstFile API in Windows Embedded CE 6.0 R2 does not issue a close request packet to the server when the server shares an empty folder.
