Hi, I have a server that run OpenSuse 10.3, this server run VMware Server and host an OpenSuse 10.3 virtual machine witch is a Samba file server for my windows clients. The goal behind having a OpenSuse hosting an OpenSuse virtual machine is to separate the configurations from the data so I can easily change the configurations without affecting the data. The host keep all the data and share it with the virtual machine with NFS v3, so the virtual machine mount the NFS share and then a use Samba 3.0.26a to share the NFS mounted folder for my windows clients. The network I use between my host and my virtual machine is an Host-only virtual network. My virtual machine use a bridged network over a dedicated 1Gb Ethernet card to communicate with the windows clients. I reuse a smb.conf from the previous Samba (3.0.25b) file server witch was functioning with absolutely no problems. The problem I have with my new Samba file server is that my Vista client have a 20 to 60 second delay when they open a MS Office 2007 file. They have the same delay with MS Office 2003 and all the Office's file the Vista clients open with MS Office 2003 are read only. I think it is a file lock issue because went I disable the file lock at the NFS mount or in Samba smb.conf file. In my case, I just cannot disable file lock in my production environment.
