ssonsvr.exe? So you are running Citrix, with pass-through
authentication, correct?
Which version of Citrix?
If you are running Citrix XP, did you apply hotfix XE103W2K126?
Have a look here, at issue 15:

If a starting program was specified under the Environment tab in
User Account Properties and if the ICA pass-through Client had pass
through authentication enabled, Ssonsvr.exe was running in the
user’s ICA session. When the user exited the application (specified
under the Environment tab in User Account Properties), the ICA
session could not be logged off; the administrator had to manually
stop the Ssonsvr.exe process. The thread that caused the
Ssonsvr.exe process to exit when the user logged off from the
application was not being started.
Now The thread that causes the Ssonsvr.exe process to exit is
started when the user logs off from the application.
