On 192.168.71.3:
cat /proc/fs/nfsd/versions
rpcinfo -p
showmount -e

On lathe and/or shop:
rpcinfo -p 192.168.71.3
showmount -e 192.168.71.3
mount -v -t nfs 192.168.71.3:/
somewhere-other-than-/net-since-youre-using-autofs
(umount if successful)
mount -v -t nfs 192.168.71.3:/home/gene
somewhere-other-than-/net-since-youre-using-autofs
(umount if successful)
mount -v -t nfs -o nfsvers=3 192.168.71.3:/home/gene
somewhere-other-than-/net-since-youre-using-autofs
(umount if successful)
mount -v -t nfs -o nfsvers=4 192.168.71.3:/home/gene
somewhere-other-than-/net-since-youre-using-autofs
(umount if successful)
mount -v -t nfs -o nfsvers=4 192.168.71.3:/

Specifying two (or more) hosts is OK.
