Time: DATE / TIME
User name: DOMAIN\MACHINENAME$
Process: res.exe (10.2.X - C411923)
Error #: 0
Error Description: Message could not be parsed (see trace file for details)
End-Users are not affected by this error. The general error-log will show one entry for every first RDS or Citrix XenApp Session that is started in the environment after the machine has booted.
