Hello experts, We have 2 Server 2016 Domain Controllers in our environment and the both should be running LDAPS. They were both working last year. I updated the certificates on both of them about a month ago, but now only one is working for LDAPS connections. I'm not sure why the 2nd server stopped working. On my bench computer, if I run u the LDP.exe test tool or use the command openssl.exe s_client -connect <DCNAME>:636 I can see the cert on the 1st DC, and make a good connection, but I get an error on the other server and cannot connect. Looking at the certificates MMC console, I can see both servers have current and valid certificates so I am really confused why the one stopped working when all I did was replace the certs.
