So I had to reinstall the primary site server the other day due to a multiple issues with management framework…
When adding DP’s back to the newly reinstalled estate I found that they could not communicate with the PS via https… when investigating on the DP’s directly, I found the following entries within its IIS website bindings:
Looks like re adding the site server as a Distribution Point involves some form of scripting of the binding values?
Either way the entries were invalid, and cannot even be entered in manually within the format above… naturally this caused the site to fail.
Moral of the story?
Probably a good idea to perform a remote clear down of a DP’s configuration if you plan to reinstall it… I think next time I will temporarily reassign all DP’s to an alternative Primary Site, before re-assigning them back!
