DNS. Let’s point all unmatched request to specified resource.

If you need to point all not existing records to a specific one, you have to create a wildcard record.
For example we have a empty test zone db.local, let’s try to resolve not existing record aaa.db.local:

C:\nslookup
Default Server: srv
Address: 172.17.14.204
> aaa.db.local
Server: srv
Address: 172.17.14.204
*** srv can’t find aaa.db.local: Non-existent domain

Now lets create an A record inside db.local with following name “*” and 127.0.0.1 as IP Address, here is result:

C:\nslookup
Default Server: srv
Address: 172.17.14.204
> aaa.db.local
Server: srv
Address: 172.17.14.204
Name: aaa.db.local
Address: 127.0.0.1
> abc.db.local
Server: srv
Address: 172.17.14.204

Name: abc.db.local
Address: 127.0.0.1

As you can see our DNS server returns our *.db.local record. This feature is not a new one and supported by Windows DNS as well as by Bind DNS.

Windows Server 2016 and Flash Player.

If you are searching for how to enable flash player on Windows Server 2016 you should keep in mind that you must install RDSH as MS recomendation.
But if you havent license for RDHS and flash player that all you need then just run from cmd:

dism /online /add-package /packagepath:”C:\Windows\servicing\Packages\Adobe-Flash-For-Windows-Package~31bf3856ad364e35~amd64~~10.0.14393.0.mum

And of course, you must restart server. Thanks to God that no reboot requred for at least ip address change like in windows 98.

Group Policy Issue. Clients with KB3163622 stop to apply some GPO.

We are faced with GP problem after installing KB3163622 update .
All Policies with security filters weren’t proceeded by updated (with mentioned KB) clients.
Following error logged by command gpresult /v:

Filtering: Not Applied (Unknown Reason)

No additional information logged in eventlog.
Microsoft says that they change processing procedure and now when you add security filter you also should add either “Authentificated Users” group or “Domain Computers” group with Read permission (Don’t add Apply access for this groups) on Delegated tab.

gpo

If you have a lot of policies with filters you can use PowerShell Script from Microsoft Gallery, this script will check all policies and add appropriate permissions.
