SMB file sharing to SBS 2011 broken?

After upgrading to mountain lion, I am unable to mount SMB shares from my windows SBS 2011. When I use "connect to server" in the go menu, I get the screen to authenticate, I type the correct server user name and password, and then it cannot connect. When I brotse, I see the server, I connect as myself, and the finder shows directory "/". When I try to go farther, I get "The operation can't be completed becausse the original item for "/" can't be found. I am in a domain environment. The "kind" is Sharepoint, which leads me to believe it connected to sharepoint instead of my SMB shares.

This is probably because another service (e.g. afpd/netatalk) is running on the server and this service conflicts with samba service. In this case the avahi/bonjour doesn't broadcast samba service. To fix this, you have to add smb.service to /etc/avahi/services:


<?xml version="1.0" standalone='no'?>

<!DOCTYPE service-group SYSTEM "avahi-service.dtd">

<service-group>

<name replace-wildcards="yes">%h (samba)</name>

<service>

<type>_smb._tcp</type>

<port>445</port>

</service>

<service>

<type>_device-info._tcp</type>

<port>0</port>

<txt-record>model=RackMac</txt-record>

</service>

</service-group>

I just resolved this symptom, which in my case was occurring on an unbound 10.7.5 Mac while attempting to mount a share hosted by an SBS 2011 (Windows Server 2008 R2) server. The fix ended up being:

  1. Reset the user's AD password.
  2. Remove the keychain entry for the server.
  3. Reboot the Mac.

Any one of these three steps by itself did not resolve the issue. In the process of troubleshooting I noticed that the issue was specific to the Mac's local user account, the credentials being used, and the resource being accessed. For example:

  • The user can successfully mount other shares hosted by the same server with the same credentials.
  • Connection succeeds using different credentials from the same local account on the Mac.
  • Connection succeeds using the user's credentials from a different (also unbound) Mac on the LAN.
  • Connection succeeds using the user's credentials from a different local account on the original Mac.
  • Using the Connect to Server dialog with embedded username/password syntax (smb://user:pass@server) didn't help.


The user had never succesfully mounted the problematic share, and had only recently been added to the AD group which has permissions to read the share. I'm guessing that the user may have attempted to access the share prior to being added to the group and somehow the resulting access denied was cached and persisted after his permissions were changed.
