CIFS problem resolution ('Duplicate Name Exists' on W2K)

[blueprint]

Hello

First of all, please excuse my english. I usually speak french. I also don't have the skills to explain why the fix my IT department found for the CIFS problem works. Anyway, here it is:

I am using Alfresco 1.4.0, running on WinXP Pro SP1. It is serving a network of 12 PCs running Win XP Pro or Win 2000 Pro.

From what my IT guy told me, the fix is fairly simple.
He just disabled the server adapter "QoS Packet Scheduler", "File and Printer Sharing" and unchecked "Activate LMHOSTS search" in the TCP/IP options dialog box.

If it works for some of you, i'd really like someone to explain WHY this works, as I am not skilled enough to have a clue!

hi,

I just tested following your idea, however, I failed to make it work. 
and I can not find the "Qos Packet Scheduler" in our my server box.
Could you share your configuaration in the  file-servers.xml ?

Anyway thanks for your post so much.

Hi, thank you for your post.
I am struggling to make cifs work with window2003 server now.
I will post back if I succeed.

Thanks again.

Hi, we had the same problem on our Windows 2003 server.
And this solution worked for us as well !
Many thanks for your post.

In fact, unchecking the "File and Printer Sharing for Microsoft network" option was sufficient to solve the problem.
Other options ("QoS Packet Scheduler", "Activate LMHOSTS search") had no effect on the issue.

Regards,
Denis

I had to do two more things to get it working as outlined in the wiki (http://wiki.alfresco.com/wiki/File_Server_Configuration#SMB.2FCIFS_Server_Configuration😞

* <tcpipSMB [platforms="…"]/>

Enables native SMB on port 445 that is used by Win2000 and above clients.

To enable native SMB support under Windows requires that the Windows native SMB support is disabled by editing, or creating, the following registry key :-

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NetBT\Parameters]
"SMBDeviceEnabled"=dword:00000000

[tommorris]

I'm a little worried. Has anyone ever got the native file-share working along-side the alfresco file-share?

It certainly seems easier to get CIFS working if SMB is first disabled…

Can alfresco comment on this?

The problem is that a client can have only one type of connection, either the Alfresco CIFS or the Windows file share. 

This error occurs if a client tries to connect to both file servers.

One workaround is to map a drive to the  alfresco FTP server using something like netdrive.
