My server 2008 r2, all firewalls to test turned off,

I try to access ldap with LDP use localhost 389 is no problem, but show to access 636
Ld=ldap_sslinit (" localhost ", 636, 1);
The Error 0=ldap_set_option (hLdap LDAP_OPT_PROTOCOL_VERSION, 3);
Error 81=ldap_connect (hLdap, NULL);
Server error: & lt; Empty>
The Error & lt; 0 x51 & gt; : Fail to connect to localhost.

What if I press the wrong turn off the 636 port connection failures?
In addition, I use adcs (the server) sent himself a SSL certificate, that I can't think where I went wrong, please tell,

CodePudding user response:

Port 636, use what service?

CodePudding user response:

Using netstat - an -p TCP port 636 has not been open,
This is the place where I was curious, I use IIS manager, take 636 binding HTTPS, tip me this port are occupied by the other services,

I am confused about, but don't know how to solve the question again,

CodePudding user response:

I use netstat - ab, results show that the svchost. Exe occupies 636 port,

I should do next?

CodePudding user response:

Netstat ano -p TCP see 636 for PID
Tasklist/SVC to see what are the service in the corresponding PID, because many services are started with svchost
