Use share located at server without SCCM roles

Hi,

The scenario is the following: sccm 2012 R2.

2 servers: first one is the server where sccm was installed and is DP too. Second server only is DP.

I need to deploy aditional software which source files are located at third server (without sccm roles).

Problem: When creating additional packages, I use a share located at the third server, and distribute the content to the second server (only DP role), but the package never distribute to the DP (in the sccm console I get an error).

The question is:

It is possible to use source files located at a server without sccm roles?

Thanks in advance!
