Printers are Offline after new update

Hello @Flyers2020

Can you try disabling SNMP on the printer?

Here is a PowerShell script from our QA if you like, or you can manually go do it in the Registry, then reboot and let us know if that makes any difference.

# Turn off SNMP monitoring for printer status
# Requires admin elevation

[CmdletBinding()]
Param()

Write-Host "Turn off SNMP monitoring for printer status"

# First set the registry key
# This affects all printer connections on this machine
$RegPath = "HKLM:\SYSTEM\CurrentControlSet\Control\Print"
$RegKey = "SNMPLegacy"

# Set this to 1 to disable, 0 to reenable.
$RegValue = "1"

Write-Verbose "Create registry key with value"
New-ItemProperty -Path $RegPath -Name $RegKey -Value $RegValue -PropertyType DWORD -Force

# Restart the spooler service
Write-Verbose "Restart the printer spooler service"
Restart-Service "Spooler" -Force

Write-Host "Finished"

Thanks

Understood. We're still continuing research on correcting the issue, thank you for your patience and feedback.

 

Just for general security reference

Server 2012   -  08/31/2016 from Microsoft

SNMP is deprecated. Instead, use the Common Information Model (CIM), which is supported by the WS-Management web services protocol and implemented as Windows Remote Management.

Server 2016   -  08/22/2019
SMB 2+ over NetBT is deprecated. Instead, implement SMB over TCP or RDMA

Just wondering if there's any follow up on this? I see from the release notes that it's fixed in v4.3.x although as yet I can't find that in Nebula I think it only goes as far as v4.2.3.96.

I was using this as my reference for the fix:
