[Samba] Software installation by GPO ( success and fail )

[L.P.H. van Belle]

Hai, In a bit testing with software deployment through GPO. 
 
Now i noticed te following. If i setup my software source somewhere on the sysvol share ( and probely any other share on the DC)
then i can deploy the software with computer and user GPO setting. Aka works ok good all settings with software deployment. 
 
Now i noticed the following. 
I did setup a share on a member server the AD Domain, i did setup the same rights as the sysvol share used. 
Now deployment with GPO does not work any more.
Not as user policy or computer policy works if i want to install before logon or after login. 
The message in event logs: 
( translated ) failed to install the error is %%1612 error 1612 tels me unable to access the source. 
 
( aka looks like the machine is unable to get to the software. ) But im 100% sure the computer can access this, 
why does it work on sysvol and not on a member server with exact the same rights on share, folder and files.
 
So im wonders who is installing software through GPO objects as machine/user policy from a member server. 
And where it works, because i cant find where this is going wrong. 
 
Thanks Louis
