Hallo,

we have major problem on Windows Server 2016 Standard x64.

This server is running in small company, and working as AD server, DHCP server, DNS server, Router, File Server, Terminal server, AppServer, and RAS VPN server.

After update KB45014702 stop working everything, was unable to connect to VPN, and was unable to connect to ActiveDirectory.
It was temporarily resolved only by uninstalation of this (KB45014702) update.
After uninstalation everything start to work, VPN working and ActiveDirectory was accesible again.
I was stoped Windows Update on this server to prevent this colapse again.
After this, when I search in formus on Internet i found many cases with the same problems with this update.
But I can not found some clear solution.

Now we have no running windows security updates.
Please can you help me to resolve this situation?

Thank you.

    Please run;

    Dcdiag /v /c /d /e /s:%computername% >C:\dcdiag.log
    repadmin /showrepl >C:\repl.txt
    ipconfig /all > C:\dc1.txt
    ipconfig /all > C:\dc2.txt

    then put unzipped text files up on OneDrive and share a link.

    SERVER is mult-homed plus a VPN. Multi-homing a domain controller will always cause no end to grief for active directory DNS. Remove the other adapter and move the VPN role to a member server. I didn't look at other files since this one's a showstopper. If problems persist after fixing things, then put up a new set of files to look at.
