Last week I had a problem with one of my Branch Office Distribution Points. It couldn’t download any new packages. Downloads from older packages where I just updated the source worked fine. In the SCCM log files on the DP I found the following error: Error retrieving manifest (0x80070035).The error 0x80070035 indicates "The network path was not found" but, the client could access the network path and the files where there. Finally I just removed the new packages from all Distribution Points and redistribute the packages. That did the trick. Everything is working like it should be.
