We have a TeraStation Pro 6 (TS-6VH18TL/R6), firmware 1.10, and have determined that it has a limit of 21 users who can connect via AFP (from Macs, obviously). My colleague came into the office on a weekend and connected and unconnected various machines to make sure that it wasn't any particular client machine -- the 22nd user simply can't connect. The share will show up, but the password is simply rejected. As a workaround we've disabled Apple file sharing on the box and all the Macs are using SMB (Windows) connections to connect, but this is causing speed issues with folders with large numbers of items, it seems. Any ideas? Thanks.
