No Printers Listed in Citrix XenApp Session - Required Service IDs Missing

Previously we talked about printing issue due to missing service / services not started. However, there is another possibility of printing issue to occur, which related to required Service IDs. From Citrix technical article, below IDs are needed and must be configured accordingly.
Account Name
Permissions
Notes
Local Service
Minimal
NT AUTHORITY\LocalService
Network Service
Minimal, network resources
NT AUTHORITY\NetworkService
Local System
Administrator
NT AUTHORITY\System
ctx_cpsvcuser
Domain or local user
Acts as a power user
Ctx_StreamingSvc
Domain or local user
Acts as a user
Ctx_ConfigMgr
Domain or local user
Acts as a power user
Ctx_CpuUser
Domain or local user
Acts as a user


Issues :

  • Users may received one or more errors regards to printing. Below are some of the error examples :


 - or - 


  • Meanwhile from server perspective, no printers listed in Printer and Faxes

  • Upon checking the services, both Printer Spooler and Citrix Print Management services are started. Issue remains although those services restarted.





Troubleshooting 
  1. Right click at My Computer, and click at Manage

  2. From Computer Management Console, browse to Local Users and Groups > Groups and check whether required Service IDs for both Power Users and Users local group are properly configured.
No required Service IDs configured. It might be accidentally removed by Admin / Monitoring System.




Resolution :
  • Add required Service IDs to their respective groups.
Needed IDs : ctx_cpuuser & Ctx_StreamingSvc
 
Needed IDs : ctx_cpsvcuser & Ctx_ConfigMgr

The is a tool to auto-create and configure ctx_cpsvcuser, BUT it is for below Citrix versions only :
  • Feature Pack 1 for Presentation Server 4.5
  • Presentation Server 4.5 for Windows Server 2003
  • Presentation Server 4.5 for Windows Server 2003 x64 Edition
  • XenApp 5.0 for Windows Server 2003 x64
  • XenApp 5.0 for Windows Server 2003 x86

    2. Windows 10 also comes with slicker and more powerful productivity and media apps, including new Photos, Videos, Music, Maps, People, Mail, and Calendar. The apps work equally well as full-screen, modern Windows apps using touch or with traditional desktop mouse and keyboard input. Like the OS itself, these apps are periodically updated with new capabilities. windows 10 vps hosting
