My PC hosts aren't showing up in Panel after installing the K12Panel Agent
A checklist for when a Windows PC has the K12Panel Agent installed but isn't appearing in Panel.
My PC Isn’t Showing Up After Installing the Agent
If you installed the K12Panel Agent on a Windows PC but it isn’t appearing in Panel, work through these checks in order. Most cases are simply a machine that hasn’t checked in yet.
Wait a Bit Longer (or Reboot)
The most common cause is not waiting long enough for the PC to check in. You can speed this up by rebooting the PC to force a check-in. A PC typically checks in within five minutes of a reboot.
Confirm the PC Has Network
A freshly reimaged laptop often has no Wi-Fi connection. Connect to Wi-Fi manually, then reboot. The PC should check in within about five minutes.
Recently Imaged Machine
If a recently imaged machine isn’t showing up, the Agent may not have received the organization “key” during imaging. Some newer drive types won’t allow the organization GUID to be written to the drive. Reimage with ReimageAny and leave the USB key in until the PC appears on the On-Ramp (usually within five minutes).
Confirm the Agent Is Installed
Check Add/Remove Programs. You should see two entries:
- K12Panel Service Agent
- K12Panel Updater Service
If either is missing, re-run your organization’s installer.
Confirm the Agent Service Is Running
In Services, make sure the K12Panel Agent service is running — it runs continuously in the background. If it isn’t, start it manually or reboot. Note: the K12Panel Updater Service does not run continuously; it runs only at system startup to check for Agent updates.
Check Your Content Filter
The Agent must reach my.k12panel.com. If the network blocks direct access, the Agent won’t function. Whitelist my.k12panel.com in your content filter, and exempt it in your proxy PAC if you use a proxy.
Important: the Agent runs in service space, not user space, and must reach my.k12panel.com before any user logs in. Unblocking an individual user’s access has no effect on the Agent. See the article on whitelisting K12Panel domains for the full list.
Check Antivirus
We have not seen an antivirus product completely block the Agent, but some may flag it as unknown. If you have antivirus installed, temporarily disable it to see if the Agent can register. If that works, add an exemption for the K12Panel Agent so it can run and reach the internet.
Confirm the Organization ID
When the Agent installs, it writes a configuration file at C:\Windows\k12panel\panel.settings.json. This is a plain text file containing the Organization ID. Open it in Notepad to confirm the OrgID is correct; if it’s wrong, fix it and reboot.
Make Sure the Asset Isn’t Already in Panel
The asset may already be registered. Check that you didn’t already adopt it into K12Panel.
Make Sure the Asset Wasn’t Rejected
On the On-Ramp, turn on the View Rejected Assets switch. This shows assets previously rejected for adoption. You can restore an accidentally rejected asset back to the On-Ramp for proper adoption.
Common Questions
How long should I wait before worrying?
About five minutes after a reboot. Rebooting forces a check-in.
I see the Agent in Services but the PC still isn’t in Panel — what next?
Confirm it can reach my.k12panel.com through your content filter and proxy, and that the Organization ID in panel.settings.json is correct.
Where is the Organization ID stored on the PC?
In C:\Windows\k12panel\panel.settings.json.
The PC was rejected before — can I get it back?
Yes. On the On-Ramp, enable View Rejected Assets, select it, and Restore it.
Why does blocking a user’s web access not affect the Agent?
The Agent runs as a system service, so it must reach my.k12panel.com independently of any logged-in user.
