Unattended Access Failing – Connecting Then Drops
We have about 100 devices we've deployed the unattended MSI to via Intune. It's been working fine since last year but as of late we are unable to log into the majority of the devices. A mixture of 22H2/23h2 (Zoom Rooms) devices. Still looking into the details (Windows updates have been paused on these devices but seeing if perhaps manual updates have been performed by one of our teams). MSI is 7.5.2 1119.0. They show in the LogMeIn rescue technician console, are online, and functional, and we can authenticate (and Intune reporting indicates the software is still installed on these devices), but after authentication it says connecting for about 20 seconds and then disappears. Happening to all of us, and on most of the deployed to devices.
Is there an optimal way to identify root cause here? I'm waiting on our onsite team to validate connectivity, restart the devices, verify no recent updates, validate what firewall we're using on these devices/any changes to Forcepoint or CrowdStrike, etc., but just curious if there might be something I'm missing in the meantime. For what it's worth I installed on one of my test devices, it didn't work initially, but subsequently it did (unsure if this coincided with a message I saw "This session has expired and can no longer be used, to start a new session this applet must be downloaded again" from the host device after the initial attempt. I closed this message and then attempted remoting in again and then it worked, however is consistently doesn't work on the other devices.
I also see that a new version of the MSI via the admin center unattended install. I've packaged it and plan on testing the new version to determine if this remediates but only want to do that if necessary. Any requirements/logs/etc. I should be homing in on, here?
Any help is appreciated!
