NSLOOKUP.EXE, delivered in WR08620, may get deleted by TCPSTART.CMD.
Some versions of TCP/IP may delete NSLOOKUP.EXE located in the \mptn\bin
directory after TCPSTART.CMD is run, usually at reboot.  The following
workarounds may be used to avoid the problem.



For those not running NFS 2.0
  REM out the call to TCPCOEX in the TCPSTART.CMD before rebooting the
  system after installation of WRx8620 for example

     REM  X:\TCPIP\BIN\TCPCOEX.EXE


For those running NFS 2.0
  Unpack NSLOOKUP.EXE from the MPTS WRx8620 FixPak located in \FIX\MPT.1
  on disk 1 and copy it to your tcpip\bin directory.  (If a TCP/IP
  fixpak is installed after WR08620 it may include an older level of
  NSLOOKUP.EXE.  Be sure to keep and use the NSLOOKUP.EXE that came with
  WR08620)
