Primary site server acting as a DP when it does not have the system role

[peanican]

I have a small site:

-no cas

-one primary site server (MP,DataBase,)

-one site system server (wsus, DP)

 

I started getting messages that My primary site server was running out of disk space. When I investigated, I saw that it was adding content to the C: drive as if its a DP (DP role is not installed this machine). When I add the NO_SMS_ON_DRIVE.SMS the content distributions all fail.

 

Is this normal for the files to want to reside on the primary site server?

 

The DP server does get updated files when I distribute the content but is not the actual exe's like on the primary server.

 

Can I disable the primary server from hosting files? If not can I move the file using ContentLibraryTransfer.exe? Any insight on what is going on would be appreciated. Thanks.
