Windows Client unable to connect to Windows DB server if weak ciphers are disabled

Question asked by Mina Medel on Jan 15, 2020

Hi Guys,

 

I have disabled all weak ciphers on a windwos 2012 rserver and has 2016 SQL installed.

1 application on the workstation is connecting to the DB on server. We found out that if this registry key is defined on server, the connection is being rejected.

 

Registry defined:

HKLM\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Hashes\SHA

REG_DWORD - Enabled

value = 0x00000000

 

My question is:

-Was the issue n the client side? do we also need to define registry entries on the client?

 

Thanks in advance
