A "Web Services on Devices"-based printer appears as Offline after you wake a Windows Vista-based computer from sleep


You install a "Web Services on Devices" (WSD)-based printer on a computer that is running Windows Vista. After you do this, you put the computer to sleep, and then you wake it from sleep. However, when you view the Printers item in Control Panel, the status of the WSD-based printer appears as Offline. You expect the printer to resume online when you wake the computer from sleep.


This problem occurs because of a timing issue that causes a race condition in the WSDMON port monitor. The race condition prevents the WSDMON port monitor from updating the status of the printer.
