So did a lot more testing today:
Test 1:
Create a new user in AD (VDITestUser1), gave user same permissions as a regular VDI user that is having problems right now after 5.3 update. Assigned VDITestUser1 to a specific linked clone (example VDI-TEST-001) in a linked clone pool (VDI-TEST) with 5.3 agent installed. Gets a temporary profile. Event Viewer reports profile errors.
Test 2:
Create a new user in AD (VDITestUser2), gave user same permissions as a regular VDI user that is having problems right now after 5.3 update. Assigned user to a specific linked clone (VDI-TEST-002) in the same pool (VDI-TEST). Before log in i uninstall 5.3 agent and remote experience 5.3 FP1, reboot and install 5.2 agent en remote experience 5.2 FP2. User logs in and user profile in C:\Users is created without any problems.
Test 3:
Use VDITestUser2, same specific linked clone (VDI-TEST-002) in the same pool (VDI-TEST). Before log in i uninstall 5.2 agent and remote experience 5.2 FP2, reboot and install 5.3 agent and remote experience 5.3 FP1. User logs in and profile brakes on Quick Start buttons in task bar, no email signature, looks like all AppData is missing. Event Viewer reports profile errors.
Test 4:
Create a new user in AD (VDITestUser3), gave user same permissions as a regular VDI user that is having problems right now after 5.3 update. Assigned user to a specific linked clone (VDI-TEST-003) in the same pool (VDI-TEST). Before log in i uninstall 5.3 agent and remote experience 5.3 FP1, reboot and install 5.2 agent en remote experience 5.2 FP2. User logs in and user profile in C:\Users is created without any problems.
Test 5:
Use VDITestUser3, same specific linked clone (VDI-TEST-003) in the same pool (VDI-TEST). Before log in i run the new CommandsPersonaManagementWin7_01062014.txt script to prepare the linked clone for maybe new Persona Management script features. User logs in and user profile in C:\Users is working without any issues, no loss of data.
Test 6:
Use VDITestUser3, same specific linked clone (VDI-TEST-003) in the same pool (VDI-TEST). Before log in i uninstall 5.2 agent and remote experience 5.2 FP2, reboot and install 5.3 agent and remote experience 5.3 FP1. User logs in and profile brakes on Quick Start buttons in task bar, no email signature, looks like all AppData is missing. Event Viewer reports profile errors.
Test 7:
Use VDITestUser3, same specific linked clone (VDI-TEST-003) in the same pool (VDI-TEST). Before log in i uninstall 5.3 agent and remote experience 5.3 FP1, reboot and install 5.2 agent en remote experience 5.2 FP2. User logs in and user profile is working correctly again.
Now you tell me, where does this go wrong. I think it's 5.3 agent that brakes something. Right now i will test it with a production linked clone pool to roll back to 5.2 agent and remote experiece 5.2 FP2.
That still leaves me with the full vdi's (FULL VM's) that a new profile is be create (firstname.lastname.domainname) and a roll back did not recover the profile.
Thnx
