I just wanted to post this in case anyone else ran into this issue.
My Casper Distribution Point on a Win Server 2008 R2 was working fine if I mounted the share using Finder.
But Casper Admin would not mount the share.
I did much troubleshooting and testing but could not find the problem.
Finally, after a call to JAMF support I found out the problem was the accounts I had set for Read/Write and Read access to the Casper Share had spaces in the passphrase, and Casper Admin did not support this.
Once the space were removed, Casper Admin would mount the share. BTW - also had to change the port to 445.
Many of you may say 'why spaces in passphrase' - well here were I work there is a tremendous push campus wide to get away from passwords and start using passphrases for increased complexity. So almost everyone uses spaces in their passphrase - it is just habit!
Thanks,
AJ.
