The purpose of this document is to help you make your applications available to the Agent client machines in Portal Manager if your Portal Manager is frozen and actually does not show any/some application even if you have followed steps as per guide: Agent Configuration => Properties => Distribution and Patch => Application => Create New Application.
1. Firstly please remove all your Portal Manager policies and packages, then create and deploy a single policy without special characters to see if this solves the problem or not.
2. If it does not help, please also stop your Portal Manager via the Task Manager and then restart it to see if it helps.
3. If it does not help either, please delete the file \Program Files (x86)\LANDesk\LDClient\DesktopManagerCfg.xml and run the vulscan /changesettings.
4. Very often there is an issue with the Portal Manager's favorites file. If you delete the user's favorites file, this should correct the issue. The file is located in one of the following locations depending on the version. The filename is enduserworkspacefavorites.json
C:\Program Files (x86)\LANDesk\LDClient\Data
Please locate this folder, delete the file and try again to see if the problem still persists. This should solve the issue. You can also create a BAT script that performs the following to delete favorite files.
DEL /s /q enduserworkspacefavorites.json
*** If simply deleting the file would not help, you can go to a client that works, locate the JSON file and copy it to all other machines in order to replace the wrong file. All this after testing on one impacted machine of course.

Logs for the Support
If despite all these actions your problem will still persist, please collect all the logs from the C:\ProgramData\LANDesk\Log folder of one of your impacted client machines as well as all the sdclient* logs from the C:\Program Files folder (x86)\LANDesk\LDClient\Data and attach them to a new case to Ivanti Support. The most important log file is this one: LANDeskPortalManager.exe.log
