First time I've seen this particular error. I can mount the share using afp just fine via finder. I verified the passwords and share names are all typed correctly. Did all the generic restarting of DPs and clients, Casper Admin even completed a replication properly, but every time I send a policy, it won't mount the DP and fails over to the default site.
The policy log just gives the generic error:
Error: Could not mount distribution point "DP2". Retrying using distribution point MAIN-DP..
I manually triggered the policy in terminal so I could add the verbose flag and got error 97:
Executing Policy Test-Policy... Mounting DP2 (DP IP ADDRESS) to /Volumes/CasperShare... verbose: Result of mount attempt: - The operation couldn’t be completed. (com.jamfsoftware.core.errors error 97.) verbose: Result code of mount attempt: 97 Error: Could not mount distribution point "DP2". Retrying using distribution point MAIN-DP...
