GPO printers missing

On the desktop - did they get a new one? or did the old printers just disappear?

We just had a similar issue across several customers. It was a Windows Update issue.

For us, in all cases, there was a window update that needed to run, not normal ones that run unattended, but the "Feature Update Windows 10, version 21H1". Once run, and rebooted, all printers and ports returned.

Which one specifically?

It's most likely the same issue. Print nightmare update or something along these lines. I've had the same issues, I went with registry workaround.

Not getting 11b error.

We are talking about this in our weekly meeting right now. Basically printing is broken, GPO and .bat printer installs no longer work in a secured environment.

I’m not marking this solved yet. Because I removed the cumulative update over the weekend and things are working. But I also didn’t change my updated GPO back. For now, users are working.

I will set a maintenance window for next weekend to reapply it and validate things.

We allowed the "Feature Update Windows 10, version 21H1" to finish and the two issues described resolved themselves after the reboot.

Just ran in to it again this morning. Here are the waiting updates. This update will wait forever, until someone clicks "Download and Install"
Once installed the printing issue was resolved.

Yeah, this is not my issue.
Server 2008 R2 running RDS and Server 2012 R2 Domain Controller.

So this morning, no one on RDS had printers again.

WTF..

So I manually added a printer direclty on the RDS server (not from the Print Server (the DC)). IT showed up immediately on all users and was able to be printed to.

So I manually added all the printers direct. Issues resolved for the moment.

FFS Microsoft...
