November Updates Issues

[Learn_TECH90]

Hello Everyone,

I installed the Updated on WS2012 DC, and I am having many issues such us: Very long log in of the domain users. Very long log out, and shared drives not accessible anymore. The scanners can not reach to the network shared folder which is on the WS2012. 

I believe it is related with the authentication and Microsoft seems to be aware of this kind of issues, but is there any temporary solution about that? 

I tied to uninstall the update and no luck.  

I tried this reg editor and still no luck: reg add "HKLM\SYSTEM\CurrentControlSet\services\kdc" /v ApplyDefaultDomainPolicy /t REG_DWORD /d 0 /f

The problems are showing at some of the users not at all of them...

Is there anything else I can try? Microsoft needs to address this as soon is possible. 

Thanks a lot in advance

Please run;

Dcdiag /v /c /d /e /s:%computername% >C:\dcdiag.log` (run on PDC emulator)
repadmin /showrepl >C:\repl.txt (run on any domain controller)
ipconfig /all > C:\dc1.txt (run on domain controller 1)
ipconfig /all > C:\dc2.txt (run on domain controller 2 if exists)
ipconfig /all > C:\dc3.txt (run on domain controller 3 if exists)
ipconfig /all > C:\problemworkstation.txt (run on problem pc)
Also check the domain controller ***System*** and ***Replication*** (DFS or FRS) event logs for errors since last boot. Post the ***Event Source*** and ***Event IDs*** of any found

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

Hello,
It turned out to be a problem on the Firewall at the end. We had a U-Turn route that we had created which was causing the issues.
Thanks a lot,
All the best
