There are 2 DP's. Do the DP's system account need to be a member of the local account (SMS_SitetoSiteConnection_XXX) on the SCCM Site server? I am getting errors when packages are attempting to connect.

No packages can be distributed to the DPs. The Primary Site server is acting as a temp DP and the packages are working on that server. So I sure there is nothing wrong with the source directory. Site server local machine (system) account is added to the local admin account on the DP's. The web stuff appears to be fine.

Add the SCCM admin account to the local admin group on the Distribution points and re-run the package to check.Sabrina TechNet Community Support
