Hmm. On my NFS server box, only version 4 was available in the server setup; no options for 4.x. I tried removing v4 client support, since I don't expect to use it, and separately I tried adding 4.1 and 4.2 support on the client. Neither of those helped: the client still insists that the exported directories don't exist, even though I can see them. Thanks for the idea though. -- Regards, Peter.
