I don't think I've experienced this problem before. A couple of work-arounds
would be to mount with an IP address (I do this on servers in case DNS isn't
around when they are rebooting and mouning remote filesystems), or add the
hostnames in question to the /etc/hosts file, most Linux systems are
configured with /etc/hosts taking precedent over DNS.

Read the man pages for nfsd and mount/mountd, there may be an option to
prevent it from doing the reverse lookups.
