Connect to LDAP server using C#

We have following server details:

Server: CN=HQITSA01,OU=Domain Controllers,DC=example,DC=net

We don't have username and password.

Our Code:

PrincipalContext principalContext = new PrincipalContext(ContextType.Domain, "example.net");

We have tried above code to connect but it throwing error: The server could not be contacted.

The right instruction should be:

var context = new PrincipalContext(ContextType.Domain, "EXAMPLE", "DC=EXAMPLE,DC=net");

where EXAMPLE here is the NETBIOS name for the domain. You can also try with 

var context = new PrincipalContext(ContextType.Domain, null);

to connect to the current domain, if example.net is you current domain.

Check the documentation of PrincipalContext object at this link for further details or this SO question.

BTW, "the server could not be contacted" looks like a simple connectivity problem.
