Mac access to shares very slow without FQDN

Hi,
I have a domain Joined Mac (10.8.5 & 10.9.4)
The windows AD is 2008 R2
The shares are on NetApp
The IP is coming from DHCP, which provides all the information including Search Domain

Now, when I go & try to access a share e.g. smb://Server/Share, it takes 10 -12 seconds to bring up the Authentication Windows,
However if I give the FQDN e.g. smb://Server.Domain.com/Share, it brings up Authentication Window immediately.

When the same exercise is done from a Windows Domain Joined computer, it works perfectly even without FQDN.


I would need to know how the same behaviour can be achieved on Mac that it works like windows client?

Dose forcing SMB1 help?

Hi Ackles,

I used to bring my Mac in very secure government networks that were MS dominant and had the same problems. That said, being the good little Net Admin I found Thursby software, ADmitMac, that turned my Mac into a true PC for AD environments. Here is a link to ADmitMac: http://www.thursby.com/products/admitmac

It worked wonders.

Hope this helps.

serialband,
The command never turns it into SMB1, that's a myth.
If you ever run Wireshark, you will see it still uses SMB1, the true way to make SMB1 is only by this command:


There's also a possibility to change all connections to use SMB1 system-wide (for all users) by entering this command in Terminal:

sudo sh -c "echo '[default]' >> /etc/nsmb.conf; echo 'smb_neg=smb1_only' >> /etc/nsmb.conf"


To restore the default SMB2 you simply need to delete the newly created configuration file (nsmb.conf) with the command:

sudo rm /etc/nsmb.conf



@Justin,
I am trying to understand why it does so? Not using 3rd party tools.

Sorry, I meant wireshark confirms it still uses SMB2
