i,
We have recently started upgrading windows 10 system to 1903 and after the upgrade we started noticing that O365 services stopped working. current solution which i can find is to enable PKCS which is not safe.
Older version of 1903 we never had this issue, only after upgrading to 1903 we started noticing this issue.
As a part of OS hardening process we have disabled vulnerable ciphers, Hashes, Key Exchanges and Client Protocols.
With same Harding earlier version to1903 works without any issues and 1903 have the issue with O365 services.
For testing, if any other entries is creating the issue i have removed the complete hardening that i can pasted below and disabled only PKCS. Still the issue persists.
So this looks purely PKCS issue with Win10(1903) in my case.
For very Registry changes i have restarted the system.
Can some please help me on it.
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\KeyExchangeAlgorithms\PKCS]
"Enabled"=dword:00000000
