Hi Bob,

Microsoft never releases a Windows Server version called 2018 r2. They only release the following LTSC channel Server versions:
Windows Server 2003 (April 2003)
Windows Server 2003 R2 (December 2005)
Windows Server 2008 (February 2008)
Windows Server 2008 R2 (October 2009)
Windows Server 2012 (September 2012)
Windows Server 2012 R2 (October 2013)
Windows Server 2016 (September 2016)
Windows Server 2019 (October 2018)
Windows Server 2022 (In preview)

And the following SAC channel versions:
Windows Server, version 1709 (September 2017)
Windows Server, version 1803
Windows Server, version 1809
Windows Server, version 1903
Windows Server, version 1909
Windows Server, version 2004
Windows Server, version 20H2

Therefore, you need to confirm the specific version of your server then find the corresponding PrintNightmare patch.
Server 2008 R2(end of support in 2021, need ESU)

'Workarounds'
Determine if the Print Spooler service is running

Run the following in Windows PowerShell:

Get-Service -Name Spooler

If the Print Spooler is running or if the service is not set to disabled, select one of the following options to either disable the Print Spooler service, or to Disable inbound remote printing through Group Policy:

Option 1 - Disable the Print Spooler service

If disabling the Print Spooler service is appropriate for your enterprise, use the following PowerShell commands:

Stop-Service -Name Spooler -Force

Set-Service -Name Spooler -StartupType Disabled

Impact of workaround Disabling the Print Spooler service disables the ability to print both locally and remotely.

Option 2 - Disable inbound remote printing through Group Policy

You can also configure the settings via Group Policy as follows:

Computer Configuration / Administrative Templates / Printers

Disable the “Allow Print Spooler to accept client connections:” policy to block remote attacks.

You must restart the Print Spooler service for the group policy to take effect.
