Hi,I have SAMBA based NAS to store my files on. So far I have just used my LAN connected Windows 7 based desktop to access the files. Even in this setup, Windows will cache the files in an offline folder, but I have never bothered since I'm always connected to the server.This weekend I upgraded my laptop to Windows 7 and redirected my document folder to the NAS. By this all my files should automatically be copied to the offline folder on my laptop which means I could also work with my files when I'm offline. The laptop is connected by WLAN. Once up and running Windows 7, I immediatly ran into problem with sync failures, indicating the files on the server were locked by another process. All subsequent attempts to manually force sync. ended up in similar problems, and just a fraction of my files were actually cached on my laptop. I have no such problems on my desktop, and all files are cached perfectly on the local disk even if really don't need it in this case.After a couple of hours of troubleshooting I more or less gave up, but decided to test one additional thing. I replaced the WLAN with a cable.All of a sudden all problems were gone.! My first attempt to synchronize the offline folder succeded without any problem.It is obvious I have some problem with my WLANresulting in a major impact on the synch. protocol. I can copy files back and forth between the laptop and the server over WLAN without any problem, but it is not possible to synch. folders. It seems like the synch. protocol is very sensitive for any network hickups. If anyone has experienced a problem like this, I'm interested to hear about this. Any ideas what might cause the problem in more detail are also welcome!

I think I can bring some more light on this problem. It's now evident there is a problem with Windows 7 offline folders and SAMBA based servers. You can find a lot of issues about this on the net. I think this is the reason behind my problem with WLAN access. It seems to be a timing issue with locks in the protocol, and when I use WLAN the failures are a lot more frequent compared to wired access.Until some clever guys found a solution for this, I think we better stay away from offline folders on SAMBA baed servers.
