User is unable to launch application, app automatically minimize permanently.


I have analyzed the issue and found a possible cause of frequent disconnection. Event Id 1000(100) for winlogon.exe is generated every time user launches the application.
On further analysis, I found that there is a limited buffer size for username i.e for the username here it is 20, if that is exceeded then winlogon crashes and application fails to launch.
Possible Workaround:
To not to use usernames longer that 19 letters.
Another solution:
