OSD Task Sequence Applications Fail to Install

Hello All,

I have exactly the same problem: impossible to install applications during task sequences (rule for 32 and rule for 64). seems to be an access denied somewhere, but where ? also error 24status received: 24 (Application download failed ).

When i check the distribution point at smspkgd$, the content is not there; maybe it's normal as this one is present in the SCCMContenLib folder. I don't understand why this folder exisit and what's the content location. Should i add access rights to this SCCMContenlib folder, or in IIS (note: only HTTP is enabled)

Thanks in advance
