I set up a private folder, gave it access to two users as well as the group I put the two users in. Then I go to the "private" folder and try to open it, enter in the users name & password, and I get a message saying the folder cannot be accessed at this time, and something about multiple connections not being allowed. I will try all users, even admin, with the same result. Then the next time I try it it will let me in no problem.
Any ideas why this happens from time to time? Could it be because I have network shortcuts to the directory? IIRC I once ran into something similar trying to access a c$ drive on another pc in the network and it had to do with network folder shortcuts under my network places, but I don't know if the same would apply in this case.
