Introduction

This article describes an issue in which the IUPnPDevice::Release() function waits longer than expected for a reply in Windows Embedded Compact 7. An update is available to resolve this issue. Before you install this update, all previously issued updates for this product must be installed.

Symptoms

Consider the following scenario on a device that's running Windows Embedded Compact 7:

  • You use a UPnP server on the Internet.

  • You disconnect TCP/IP on the device.

  • You have no LAN cable connection attached to the device.


When the IUPnPDevice::Release() function is called in this scenario, the function waits dozens of seconds for a reply. Typically, you expect the function to obtain an immediate reply or to wait for the time-out period that you set.

Cause

This issue occurs because, when TCP/IP is disconnected and no LAN cable is connected to the device, the IUPnPDevice::Release() function must wait for the UNSUBSCRIBE request to finish.

Resolution
