One word: upgrade. 1.0rc15 is totally outdated and unsupported. There have been so many fixed since then - many of which relate directly to NFS problems - they are too numerous to list. Personally, I'd go ahead and move to 1.2 rc2 (once you've got it working on a test server), but you need to go to at least 1.1.13... -- Best regards, Charles
