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 DP site system server role. These are the IIS configurations of 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 what are 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 which are created in IIS for SCCM DP. Those are for content and signature files.
ACNCM2016\Sites\Default Web Site\SMS_DP_SMSPKG$
ACNCM2016\Sites\Default Web Site\SMS_DP_SMSSIG$

There are two Virtual directories created in IIS for SCCM DP:- SMS_DP_SMSPKG$ and sub folders where SCCM applications and Packages contents are stored – DataLib, FileLib and PkgLib ! SMS_DP_SMSSIG$ is the signature folder.
