SAMBA and NFS

[Paul Boal]

I've got an odd configuration that seems to be encountering a serious 
problem.  Here's a basic diagram of the system:

NETWORK:
    +----------------+              +----------------+
    |    BOX1        |              |    BOX2        |
    |  -2.2.13       |              |  -2.2.16       |
    |  -Mandrake6.1  |              |  -RedHat 7.0   |
    |                |              |                |
    |                |-------+------|                |
    |  -SMB server   |       |      |  -NFS server   |
    |  -NFS client   |       |      |                |
    +----------------+       |      +----------------+
                             |
    +----------------+       |
    |    BOX3        |       |
    |  -WinNT 4.0    |       |
    |  -SP5          |       |
    |                |       |
    |                +-------+
    |                |
    |  -SMB client   |
    +----------------+

PROBLEM:
BOX2 has a directory that is exported through the NFS server.  BOX1 
mounts that directory and then shares it using SMB.  BOX3 maps to that 
SMB share and then tries to rename one of the directories.  BOX2 and 
BOX1 simultaneously lock up!

BOX3 can map the drive fine.  Open, Save, Create, and Rename 
documents.  But any work with renaming or creating a new directory 
fails.

BOX1 (in a terminal) can Open, Save, Create, and Rename files and 
direcotries just fine on the mounted NFS directory without any 
problems.

Neither BOX1 or BOX2 report any errors.  The just hang when BOX3 tries 
to create or rename a directory on the share that is the NFS mounted 
directory.

Thanks for the help!
