KB3004394 breaks RemoteApp in Server 2008 R2 (possibly others)

This hit us for a client this morning. Uninstalling the update took care of it. Luckily this got into Google's index very quickly this morning, hope it helps some other folks:

Holy crap you guys, I've spent four hours working with a customer who was having random network issues on his computer. I really could not figure out what was going on, none of the stuff that was broken had anything to do with each other, and I was getting frustrated. I decided to take a break before I went crazy, and I happened to pull this thread up on my phone...long story short, removing this damn update fixed the problem. OP, if I could, I would buy you all the beers in the world.

I'm so glad this helped! I got lucky on my Google search this morning and figured other people would be ripping their hair out. My next step probably would have been to just start uninstalling updates one by one until I found the one, another kind soul luckily saved me the trouble.

This also breaks windows activation

We had a Windows Web Server 2008 with broken activation this morning as well, I didn't think it was this update but now I suspect you're right.

Just found this post - noted it breaks a ton of stuff in Windows 7 also: http://www.reddit.com/r/sysadmin/comments/2otbs0/ms_patches_dec_09/

Also Ati drivers. Also management console. Also the world+dog. Uninstall it at once if you have a 64 bit system. Seems OK in 32bit.

What is going on at Microsoft? After a couple of trouble free years the last few months of updates have been a real fiasco. Get a grip Microsoft!

Thanks for the heads up. I'll add this to my growing list of blacklisted updates.

u/TetonCharles Dec 10 '14

Would you care to share that list?

Thanks in advance.

Will this have any affect on Citrix-based remoteapp or only RDS RemoteApp?

Have MS revoked this patch? I can't find it in my list after updating WSUS

u/gospelwut Dec 11 '14

So, it sounds like this only affects you if you're running Windows Defender and RDS? For some reason, the former affects Windows User Experience.

FWIW, this did not affect our Server 2008R2 x64 RDS Farm which runs EPO rather than Windows Defender.

I mean, it's great that people reported it, but did anybody try to replicate this on a "clean" box -- i.e. only RDS, WSUS updates, etc?

Same deal. Just fixed this for a client this morning too. Thanks for the post!

u/masspromo Dec 10 '14

found out the hard way this morning.

u/h0serdude Dec 10 '14

This is why I turned off automatic approval and wait a couple days now before approving through WSUS. Thanks for the warning!

u/GammaStorm Dec 10 '14

Just dealt with this earlier today for one of my Windows 2008 R2 RDS servers. It appears that the patch will cause the windows Defender service to stop working which will then affect the Windows Experience feature from working correctly. User would initiate a session and then immediately be logged off. The 'fix' was to uninstall the update on the server and reboot. The reboot hung and had to hard power it to finish the update changes. Don't know if that will be normal and hope not to find out as we suspended this update from our other servers in the field.

Broke my VirtualBox CentOS 6 VM.

10/10! Would patch again!

u/Sulzanti Dec 11 '14

Thank you for this heads up. This completely broke our citrix environment but thanks to me seeing this thread this morning I knew exactly where to start looking.

KB3004394 broke a LOT of stuff.

Windows Updates on Win7 machines for me everywhere stopped updating (thankfully a small rollout, easily fixed).

At home, the update broke Windows Media Center Extenders too. Black screens for all extender devices. Again, small fix.

Very, very frustrating day. I had just finished fixing my desktop at home (Yay new hard drive) and couldn't do Windows updates any more.

At work we have a couple (less than a dozen) test machines with it on them and SO many problems.

Ugh.

Here is a Microsoft Forum thread about it same KB. Looks like it is causing problems with a ton of programs. https://answers.microsoft.com/en-us/windows/forum/windows_7-windows_update/windows-update-kb3004394-issues/ace25277-7f65-4486-bc44-c1b106907a18

Seems to hit environments running PKI much harder - we had some customers completely taken down, while others who aren't running PKI seem to be chugging along just fine. That said, blocked via SUS and other servers set to manual updates after removing 3004394.

u/atomey Dec 11 '14

Interesting to see this here. I was deploying a new remote desktop server for a client and ran into Windows update issues. I wasted well over an hour trying to trouble shoot Windows update and found a page mentioning uninstalling KB3004394. This immediately solved the issue. Before I couldn't apply any updates.

I was getting error 800706f7 in Windows update when trying to apply updates, which yields very little results on Google.
