Library /sys$common/syshlp/tcpip$nslookup_help.hlb set, retry  *Conan The Librarian (sorry for the slow response - running on an old VAX)

   If a reply to a request is not received within a certain
   amount of time (changed with set timeout), the request is
   resent. The retry value controls how many times a request
   is to be resent before giving up.

    set retry=number

   DEFAULT:
    set retry=2
