Does the VMS client mount over UDP only? If so, that is probably the 
problem. Recent nfs-utils (as used in Fedora 25) disabled UDP support by 
default, as the major NFS clients have supported TCP for many years; see:

https://patchwork.kernel.org/patch/9591703/

Try editing /etc/sysconfig/nfs and adding -u to RPCNFSDARGS; that way 
you should not have to mess with downgrading nfs-utils. See rpc.nfsd(8).

Alternatively, perhaps you can get your VMS client to use TCP. That 
would probably be better, if it works.
