I missed this: when you open the properties of the SAMBA 4 box in Server Manager, you cannot edit the description. We need to investigate this and bring up a RPC or changing one.
Created attachment 3833 [details] SRVSVC pipe improvement The change description operation isn't such easy to implement, because we rely on a loadparm parameter to display it (therefore it can only be changed through the "smb.conf"). Therefore I would apply this patch which returns the more correct message "NOT SUPPORTED".
Comment on attachment 3833 [details] SRVSVC pipe improvement Revert because it doesn't fit.
Let us close this since the write implementation of the description is impossible since our "smb.conf" is read-only. But I think the change using the text editor should be enough - we really don't need the RPC support for this. Therefore closing this with "WORKS FOR ME".
