Really banging my head against the wall on this one. I have sporadic issue where when a user logs back in, or unlocks their Windows 7 64-bit virtual desktop the task bar will blank out, and the machine is frozen for 15ish seconds. Have found killing explorer.exe or sending a ctrl+alt+del helps resolve the issue faster, but have been unable to find a root cause.
Environment:
-Horizon 7.4
-View Agent 7.4
-Windows 7 64-bit
-2 vCPU and 6 GB vRAM
-vmxnet 3 NIC
-PCoIP protocol
Items attempted so far:
- Ensure power settings are set to optimal
- Ensure Symantec is not hanging a process
- Boot to safe mode and remove iconcache.db (way to much googling here)
- Remove profile
- Gave user new machine
- Re-imaged physical device
- Re-install View Agent and VMTools
- Ensure no other monitor drivers were present from 3rd party software.
The problem I am having is it is difficult to troubleshoot as it doesn't happen every time. I see it more when users are switching between dual monitor thin clients to laptops or vice-versa. Logs haven't given me much direction. Anyone else ever experience this?
