Yosemite can't connect to my NAS & other weirdness

Hi


I'm running Yosemite 10.10 on an Early 2011 15" Macbook Pro i7 with 8GB of RAM. The machine is connected to the network via Wi-Fi and my network is managed by a SKY router. All devices are configured to use DHCP to obtain their IP address from the router.


I have two NAS boxes on my network, a Western Digital MyCloud and a Buffalo Linkstation Pro.


Since upgrading to Yosemite I cannot access the Linkstation NAS box.


I can ping it on the network and I can call up the configuration pages in a web browser using the ip address, I can also access it from windows devices.


However if I try to connect to it using my mac it fails every time.


I use Go->Connect to Server then put in the details of the share, I'm prompted for a user name and password as expected but then the process stalls for several minutes before finally failing with the following error message.


'There was a problem connecting to the server "xxxxxxx"

Check the server name or IP address and then try again. If you continue to have problems, contact your system administrator.'


I've tried specifying smb, cifs, and even afp in the connection attempts but they all fail.


The Western Digital NAS works OK although it's a bit slow to make the initial connection.


The other weird thing is that my Macbook keeps changing it's NETBIOS name and I don't know why. I named the machine ChristophersMBP but it keeps getting numbers appended to the end of it. It's currently up to ChristophersMBP5.


The whole thing is very frustrating especially as if I boot Windows 7 using bootcamp it attaches to the share without any problems.


And help or advice would be greatly appreciated.

MacBook Pro (15-inch Early 2011), OS X Yosemite (10.10)

Have you checked in Keychain Access and deleted all old saved password entries that refer to your NAS? Use the search field in Keychain to search your login keychain for any old entries related to the names of your NASs. Delete those old entries as they may be interfering with your attempts to connect. Once you connect successfully then Keychain will remember the new settings for you.


I love what Keychain does for me but have seen old entries cause odd issues like this many times including NAS connectivity and WiFi connectivity.

Thanks for your reply Tim,


Yes I tried clearing out all keychain entries for the NAS but to no avail.


I even cleared out all the entries, renamed the NAS box, renamed my Macbook back to what it should be and then rebooted Macbook, NAS and router in an attempt to ensure all were using the most recent settings, still no luck.


At this rate I'll be casting runes and searching for a sacrifice to the gods of IT to get my NAS usable again! 😟

It looks like I've found, if not a fix, then at least a work around.


I was searching around the web and found other people having the same problem with their machine name changing.


The fault seemed to be caused by "Wake on LAN" being enabled on the machine. I checked my machine and, sure enough it was enabled.


Quite why I'd want wake on LAN enabled on a laptop I'm not sure so I had no problem with disabling it.


I disabled wake on LAN, renamed my computer again and rebooted it.


Now I find I can successfully connect to my NAS box!


This is a guess but I wonder if the renaming was causing problems with DNS or reverse DNS lookups?

I have a similar problem and still could not solve


I have a Synology NAS and could mapping normally before I update to Yosemite.


After the Yosemite update,My MBP could not connect to the NAS ( did not appear when on "shared" ) when I connect by WIFI.


The surprise thing is the NAS appear again when the MBP connected with a LAN wire.


I feel confused.
