Force Finder to log in as Guest to a SMB share
Solution 1
In Mac OS X 10.7.3, I used the following string in Finder's "Connect To Server..." (Command-K) for a similar server in my office:
smb://Guest:@serverAddress/volume
You need both the ':' and "@". I believe it works out as UserName:Password@address .
After the volume appeared, I tried to put it in my shortcut bar, but it wouldn't stay.
I made an alias, and tested it after disconnecting. It worked fine. No window appeared to choose "Guest".
Solution 2
This is probably what is happening to you: Finder will try to connect to your share using AFP instead of SMB, if unconnected and both daemons are running on the server and AFP is being advertised via Zeroconf. Not advertising AFP using Zeroconf (avahi/whatever) should fix this. Time Machine should still work.
Solution 3
Create a file called ~/Library/Preferences/nsmb.conf and add to it:
[default]
minauth=none
Disconnect from your server, reconnect and try again. This worked for me (I had the same problem).

I have a QNAP NAS that offers a few SMB shares. As I'm in a trusted environment, my shares are accessible as guest rather than with a combination of username and password.
Problem
Now, when I click the name of the device in Finder's sidebar, I get the black "Connection failed" bar, with the option "Connect as...". When I click that, I receive:
I can however press ⌘ + K and enter the server's name manually, which gets me to this window:
Here, I have to select "guest". Now, I can select one of the shares to connect to, and I'm finally connected to the server. If I select it in the sidebar, I get a list of all shares available, because I'm connected as "guest", obviously:
What I need
Well, as soon as I unmount all shares, I have to go through the same procedure of manually logging in as "guest" again, which I find quite annoying.
Is there any way I could get Finder (or the underlying SMB client) to know which credentials to use?
Or should I look for the solution rather on the server side? (I know that other SMB shares seem to work fine in my network)
Diagnostics
The only thing I can get out of Console.app is:
5/15/11 7:36:40 PM /System/Library/CoreServices/Finder.app/Contents/MacOS/Finder[200] SharePointBrowser::handleOpenCallBack returned 64
This message occurs when I click the name of the SMB server in the Finder sidebar.
Here's the output of `smbclient -L meredith -U guest -d=2

Also, things I've tried:
- There is no relevant entry in the Keychain (but why would it, I'm only connecting as guest)
- Connecting with user name "Guest" and empty password logs me in but still after ejecting the last share, I get the same "Connection failed" error as before. The appropriate entry is made in the Keychain but obviously has no effect.

slhck about 13 yearsNope, the article is for OS X 10.3 and dates from October 2008. Also, I can't store a username/password when I'm connecting as guest.
-
slhck about 13 yearsNo, unfortunately there is no entry for the host. I've already tried looking there. As said before, the Keychain won't store entries for guests.

Smurf64 about 13 yearsTry typing "Guest" with a blank password and check the Remember password box.
-
slhck about 13 yearsThat was a good idea, but still doesn't work.
-
Smurf64 about 13 yearsDid you try completely deleting the entry in the Keychain?
-
slhck about 13 yearsYes, I tried with the Guest entry and then deleted it again, still no avail.

Bradley Flood over 9 yearsThis also worked great for me to stop OSX automatically logging in as Guest, by adding
username:@
before the host name, as you've said. Thanks.
