Aha, you are using DECnet/Plus (aka Phase V). After making changes via
decnet_register you need to flush the dns cache.

   $ mcr ncl flush session control naming cache entry "*"

and I cannot remember now whether this is good for the whole cluster or not.
If in doubt, execute it on each node of the cluster.

The simple shortcut for remembering that command is not to bother, and as
long as you have terminal copy and paste handy, you can save some typing
too.  Simply invoke NCL (via mcr ncl) and at the NCL> prompt issue

NCL> help flush

and you can select the command out of the output.

another tip is to define NCL as a command in your login.com:

$ ncl :== $ncl

and then you don't need to bother with "MCR NCL" or "RUN SYS$SYSTEM:NCL"
to invoke the utility.
