  1. Hello Anoop,

    This is really nice and informative blog.

    Can you also share some documentation about IIS configuration for WSUS for IBCM facing server where SSL will be enabled?

    Many thanks,

  2. Really most odd statements here:
    Browse IIS website option will work for SCCM content library folders like – DataLib, FileLib and PkgLib

    That will not happen on default install! Not on localhost & not across network

    One will ALWAYS get 403 – Forbidden: Access is denied.

  3. Hi Anoop,
    I have faced an issue in Windows deployment after version upgrade. error was “8007002” in task sequence. I have opened the client deployment log and find the error was IIS 404 in “propfind /sms_dp_smspkg$/”. i went through this page and confirmed the values are equal to my settings. finally i found that “SCCMContentLib” folder permission was missed for IIS/Users. i have added users with read permission and my issue is resolved. You may add a line for checking the NTFS security of the mentioned folder in you blog.
    Thanks Anoop for giving a hint
    Regards
    Vinod

  4. Hi Anoop
    I am having an issue with iis certificate being expired.
    I have sccm server 2012 and the iis certificate has expired.

    I generated a new certificate. However, when I import the new certificate I get an error:

    Mismatched Address

    I believe I generated the cert. with the wrong information.
    Should I use https://localhost as the CN
