I have a problem with Pass-through authentication on publish desktop.
A Receiver Enterprise v3.4 is installed on XenApp servers 6.5 RP1 for publish applications.
Users are receiving intermittently the following message “The logon method is incompatible with this server. Your logon method has been changed to prompt user”
When the problem appears, SSONSVR.exe doesn't exist in the user session.
I believe it is caused by a memory error that causes it to crash and it was mostly in Windows XP. Microsoft was supposed to release a fix but I don't think they have yet and probably never will.
