I was using samba 2.2.3a on Suse 8.0. After Updating my Win2K with recent MS patches, I was not able to connect to my shared printers anymore. So I've decided to update to Samba 3.0.7. Printers seem to work now, but now I got some troubles with my OS/2 Machine. LAN-Drive folders don't get filled-up anymore. The drive seems to be successfully connected, since used/free bytes are shown. Switching to a command line and doing a "dir" on that drive, also works fine. So I'm able to use the LAN-Drive but not on the Desktop (WPS). I've gone back to 2.2.3a, since I'm using OS/2 more than Win2K.
Please retest against a current release and reopen if the issue still exists.
