Configuration - DP Shares - Permissions

Once you have created the distribution share on your site server (primary or secondary), you'll need to set up share and security permissions to make it work properly.

I enable the shares and besides the defaults, I make the following changes:

Share - Everyone - change to Full Permissions

Security - Added the SMS Administrators group with Full Permissions; Added the SMS_SiteSystemToSiteServerConnection_[site code] (local account) with Full Permissions

These settings work great for me.
