[RndTbl] NFS problems

I'm trying to get FreeNAS (based on FreeBSD) to serve up NFS shares. It keep failing with nfsd: Can't bind to tcp addr *: Address already in use Which doesn't make sense. I tried binding to a specific address (the IP address of this server) and I get the same message, but with the IP address instead of *. No other services are running on this server, other than http (80). Where do I start? Thanks, Kevin
