Windows 7 SMB connection refused

I have a 2ghz Mac Mini with OS 10.8.4 server running on our network. AFP connections are fine as are most SMB windows shares (multi-platform environment, Windows Server 2008 also on network) My problem is mainly with one Windows 7 laptop that drops connection and can only be reconnected by rebooting both the laptop and the Mac Mini, then remapping the drive. Happens almost once a day. I've tried various work-arounds I've found (turning SMB sharing off and on again, etc.) but nothing seems to work.

Mac mini Server (Mid 2011), OS X Server

What's in the logs? Anything relevant to the outages? (Launch Console.app and have a look, if you haven't already done so.)

Is DNS on the client OK? On the server? DNS errors can cause transient outages.

(I'll assume you've already de-tuned the Windows security registry settings to allow it access into the OS X Server box; that this is transient, and not something that always blocks access.)

The log file this AM when she tried to log in showed this:

7/31/13 8:00:08.605 AM sandboxd[5115]: ([5112]) smbd(5112) deny job-creation

Any relevence? I'm not very good at reading these log files (there is a lot more if you'd like me to post it, not sure if anything pertains to login though}

DNS all seems consistant, and yes Windows has access. There are another half a dozen machines running various versions of Windows that have no problem with access. She has the only Windows 7 laptop, the only variable I can think of.

Donno; there are a couple of previous similar-looking discussions, with one listing this (long) thread as containing a fix for this.

Is it a windows 7 home machine? Vista and 7 non business versions are handicapped by ms in that the don't support all smb versions out of the box. You'll need to modify the local security policies. There's a great article at http://www.tannerwilliamson.com/2009/09/14/windows-7-seven-network-file-sharing- fix-samba-smb/ that should be able to help you out.

No, it's WIndows 7 Pro. I did find while looking that up that it needs the Service Pack 2 update, I'll install that and see if anything improves. Also will check out the link and see if anything pops out at me.

Still check the security policies from that article, we've had a few pro machines that were not set properly too.

Thanks. I went through the article and changed the SMB permissions to what (if I understand correctly) are pre-Windows 7 configuration. Now it's wait and see.

Well, I was hopeful, but no luck. Monday morning she logged in to her computer and was refused connection to the server (invalid login credentials) So I had her restart, remove her mapped connection to the server, then remap the drive. Her login was then accepted. Windows IT guy points a finger at SMB issues with Mac Server, but only WIndows 7 seems to be a problem, and then mostly just this one laptop (on rare occasions a Windows 7 desktop gets a refused connection)

Had the same problem, used the terminal-mount method to try to fix it. It gave me an error message "mount_smbfs: server connection failed: Cannot allocate memory" which directed me to a microsoft support page that actually fixed the problem for me (courtesy of Anders for pointing to a solution: http://superuser.com/questions/464600/macbook-pro-suddenly-unable-to-connect-to- windows-shares):

http://support.microsoft.com/default.aspx?scid=kb;en-us;177078

So the problem seems to have been on the Windows-side.
