This morning I upgraded to OS X LION 10.7.
after the upgrade my Lacie Network Space (NAS) isn't working anymore over the AFP protocol.
this is the error I got :
ps: the xxxx should be an ip address but I photoshoped it, cause i don't like private information to be leaked.
Anyone who has the same problem. I contacted LaCie support line, they say it's a known problem at every NAS manufacturer and it's apple to do an update for this issue.
