    Default problem with the AD CS

    i installed the Windows server 2008 R2 Enterprise server on the VM, and recently installed the AD CS on it , after i created the server certificate and try to access it on the IE, was not successful. then i look up the even ID on event viewer :"could not connect to the Active Directory , Active directory certificate services will retry when processing requires Active directory acess" Event ID : 91, Level: Error source: Certificateion Athority. then i do some google search tried to solve the problem. here is what i did below:

    1. ping server name : MHSERVER08EN.MH.COM , it is sucessed
    2. ping server IP4 address: successed.
    3. used the Nltest /sc_verif, then got this message "MHSERVER09EN.MH.COM I_Netlogoncontrol failed: status=1355 0x54b error_no_such_domain"

    Please excuse my english grammar and Please give me some recommendation, let me know if you need more info to dignosted this problem.

    Many thanks.

    Hi Mandy,

    Can yo provide a little more detail on how you installed AD CS? Like can you explain your AD, CA/PKI setup a little more?

    Perform a telnet test from CS to AD to check if the required ports are open: Firewall Rules for Active Directory Certificate Services - Windows PKI blog - Site Home - TechNet Blogs
