After installing OS 10.7 Lion, I can no more connecting to my Lacie 2big Network 2 (automatic DHCP). On an anther Macmachine (Snow Leopard), there is no problem!

A message appears (in Apple File sharing): There was a problem connecting to the server. The version of the server you are trying to connect to is not supported.

Does that mean, that the Lacie 2big Network is not supported with the new OS 10.7 Lion ???? (I have already downloaded the new update from Lacie, but no result.

Is that a problem with Mac or Lacie

Thanks for your help

    Sorry, but it would be too early to tell which or both could be the reason. If the Lacie drive is connected by wireless or wired to an AirPort Extreme or Time Capsule, it wouldn't necessariy be caused by upgrading to Lion.


    However, if the Lacie is a NAS device, then the newer version of AFP that comes with Lion may not be able to communicate with the version used by the Lacie.

    Many (perhaps most) 3rd-party NASs won't work on Lion without upgrades.  Contact LaCie.

    Apple uses afp as connection protocol and it changed in lion,

    Nas builders still need bring update but they blame if you call their support line



    It seems that apple deleted DHCAST128 in Osx lion 10.7

    Because they say it's nit secure enough,

    Seems that most nas systems use this.


    This is how to put it back: ( disables time machine function on nas )




    Open Terminal

    sudo chmod o+w /Library/Preferences

    defaults write /Library/Preferences/com.a​pple.AppleShareClient afp_host_prefs_version -int 1


    reboot your Mac


    Connect to the nas so it can make a profil


    Open Terminal

    sudo defaults write /Library/Preferences/com.a​pple.AppleShareClient afp_disabled_uams -array “Cleartxt Passwrd” “MS2.0″ “2-Way Randnum exchange”

    sudo chmod o-w /Library/Preferences


    Reboot you Mac again


    Now it should work





    To turn it off again: ( default on lion)


    Open terminal

    sudo defaults write /Library/Preferences/com.a​pple.AppleShareClient afp_disabled_uams -array-add “DHCAST128″

    I'm having the same problem after updating to Lion. I contacted LaCie but they didn't reply, im still waiting. In the meantime i think i'll try Marcelleke solution.

    PC Magazine indicates that LaCie is working on an update to make their drives Lion compatible.

    Apple OS X Lion, NAS Issues Widespread, Could Take Weeks to Fix

    LaCie representatives were unable to be reached at press time, although a support representative contacted by said he expected a fix "sooner than later," he said. "I don't know exactly when it;s coming, but it could be as early as next month. It's generated a lot of calls." LaCie's OS X Lion support page notes that many LaCie consumer and professional drives, such as the Network Space 2, Network Space MAX, Wireless Space, d2 Network 2, 2big Network 2,and 5big Network 2, among others, can't be accessed via Apple's Time Machine.

    Someone posted a link to this NAS Lion workaround but past NAS workarounds for NAS/Time Machine were a nearly universal unhappy experience. I don't have a NAS so have no way to test the workaround to see if it even works temporarily. Plan for NAS data corruption if you choose to use it.

    REMEMBER my solution doesn't solve the time machine abilities of nas systems !!!!

    it only reactivates the file acces trough the AFP protocol.

    you also can do it by SMB to acces the files.


    BUT for time machine YOU NEED to use the proper AFP protocol as it is in LION.



    LACIE just annoucned they are in progress creating an update to fix the issues.

    so i would just wait. they have putted a highest priority issue so it's should be released by monday / tuesday.




    do not forget to deactivate it again !!!!! after getting an update of lacie:

    Open terminal

    sudo defaults write /Library/Preferences/com.a​pple.AppleShareClient afp_disabled_uams -array-add “DHCAST128″

  • Marcelleke Level 1 (5 points)

    Lacie rolled ou an update this night please check it fixes the issue

  • Chris Kojak Level 1 (0 points)

    Could you post the link? I can't find this update. The automated update of my lacie 2bigNetwork can't find it, too.

    Thank you.

  • curiousg3orge Level 1 (0 points)

    If you would be so kind as to post the link to the update - I'm having the same issue with my Network Space Max 4TB

    Much appreciated

  • bilby91 Level 1 (35 points)

    i was not able to find the update. We will apreciate a  link , thanks.

  • Marcelleke Level 1 (5 points)

    The update does not FIX the TM but AFP Acces to the files is restored.

    Apparantly they are first testing it on the Network Space 2 devices.



    these are the public releases


    we asked for a beta and received a beta for .94 and it solved all the problems.

    I asked them when they are pushing this update to the devices. no date set yet.


    as i told apparantly only NETWORK SPACE 2 does get the update first.

    they want to have the full solution and test it out on the publiek before pushing it to all the devices which are more used in small companies

    Man... This was bad timing for me. Installed Lion the other day, and just got the Lacie 2Big Network 2 drive in the mail yesterday. Needless to say I was going nuts trying to figure out why I couldn't log into the shares in finder, or make Time Machine work.

    Luckly I found this thread. And of course, installing and running the Lacie Network Assistant software on another computer with Snow Leopard, I was able to log in (AFP), and also set up time machine in seconds flat...

    Hopefully Lacie will be getting that update out soon.

    I have the same problem with my Conceptronic CH3HNAS and have found a free and easy solution.


    Since a lot of people report they are able to access their NAS using apps other than the Finder itself, I decided to look for a free Lion-compatible File Manager to use instead of Finder.


    I have found muCommander ( ) and indeed it works fine. All I did was click on the button highlighted bellow, go to "bonjour services" and select my NAS. It prompted me for my username and password and voilá, it works fine.

    I keep Finder for everyday use and just load muCommander when I want to access the NAS. At least now I don't have to start my WinXP VM anymore just to access it.


    Hope it helps you.

  • Gunbu Level 1 (0 points)

    Thanks for the advice, Governa. I checked out mucommander and I think it's a great temporary solution. Seems a lot more straight forward than the Lacie dashboard file browser.
