Symptoms
When using the PN Client on an embedded Windows NT or Windows XP device with Single Sign-On (SSON) enabled, the Ssonsvr.exe process may fail to start. Therefore, SSON fails when making a connection to a published application.
Resolution
Verify that the file, MPnotify.exe, is present on the device. This file can be copied from an equivalent version of Windows NT Workstation or Windows XP.
