SYMPTOMS
On a Windows Server 2003-based computer, an application that calls the DsUnBind function may crash.

This problem prevents various applications from working correctly. Typically, this problem affects Windows Deployment Services (WDS). By default, a thread in WDS updates the image-related settings every 15 minutes. This problem may cause the WDS service to crash during this update. Then, all clients that are connected to the WDS server are disconnected. Therefore, the WDS deployment jobs fail.



CAUSE
This problem may occur because the DsUnBind function incorrectly manages the input parameter.
