Each NIS map has at least two additional keys that are interpreted by the YP utilities, YP_MASTER_NAME and YP_LAST_MODIFIED:

http://docs.sun.com/source/806-4251-10/referenc.htm

# YP_MASTER_NAME
# YP_INTERDOMAIN (set with -b option)
# YP_SECURE (set with -r option)
# YP_DOMAIN_NAME (set with -d option)
# YP_OUTPUT_NAME
# YP_INPUT_FILE

As I recall your error indicates that your ypservers map does not have the YP_MASTER_NAME key in it. If you do a dbm -u ypservers it'll dump all the key-value pairs in the database that was built by ypmake.

The easiest fix is to copy a known-good version of the ypservers.dir and ypservers.pag files from the NIS master down to this slave server using FTP or what have you, rather than ypxfr. They'll be in /var/yp/`domainname` on the slave, as I recall.
