Hi Thomas,
In short -the share permissions look FINE... grr... it seems to be setup perfectly fine.
But, have verified, again and again. And rebooted, and verified again too! If I add the altservice account explicitly to the share permissions its OK and I can see the subfolders and deployment works. Remove the account, then the folders disappear and deployment hangs forever.
The administrator account however always works, and the altservice account is definitely in the administrators group. I even got a couple of others here to confirm what I'm seeing, and they are as confused on this one as I am.
I have also tried creating other accounts and adding them to the administrators group. When mapping a drive, these too see an empty deployment folder.
Tried explictly adding the everyone group with full permissions at the share level, and that didn't help either.
I did the install as administrator by the way, and then entered the altservice admin account details in during the install.
