Fix SCCM Default IIS Configurations DP MP Troubleshooting Issues ConfigMgr Configuration Manager? I think this post will help us to understand the default settings of IIS when it’s installed and configured by SCCM / ConfigMgr vNext (2016) itself.
IIS role is installed and configured by SCCM when you install the DP site system server role. These are the IIS configurations of the SCCM vNext TP 3 lab. I’ve seen SCCM admins change the IIS settings manually to work around some issues.

However, it’s hard to find out the default settings of a freshly installed SCCM server once we change IIS configurations. Probably, this post may help in those situations. The version of IIS is IIS 8.
Following are the two applications that are created in IIS for SCCM DP. Those are for content and signature files.

Directory Browsing is enabled for these package content virtual directories:-
Authentication of SCCM related IIS virtual folders is also important:- Windows Authentication is the only authentication method IIS enables kernel-mode authentication.
Edit SCCM IIS-related applications using the following:- We can test the authentication and connectivity from this IIS wizard.
Websites of the root virtual folders like SMS_DP_SMSPKG$ and SMS_DP_SMSSIG$:- 404 not found error. Browse options won’t work!

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?
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.
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$/”. i went through this page and confirmed the values are equal to my settings. finally i found that “SCCMContentLib” folder permission was missed for IIS/Users. i have added users with read permission and my issue is resolved. You may add a line for checking the NTFS security of the mentioned folder in you blog.
Thanks Anoop for giving a hint
I am having an issue with iis certificate being expired.
I have sccm server 2012 and the iis certificate has expired.
I generated a new certificate. However, when I import the new certificate I get an error:
I believe I generated the cert. with the wrong information.
Should I use https://localhost as the CN
OMG, this was article was a life saver for me. I was facing many issues in my SCCM after check that i could fix Thank you so much Anoop
In my cause the tick for “Require SSL” was missing in SSL Settings. This caused that http://servername/SMS_DP_SMSPKG$ returned HTTP Code 404 instead of Code 403.
How about adding Part II and go over all the details when configuring your DP’s using https/certificates therefore explaining the authentication that goes on for the following virtual directories.
