Re: [nv-l] identical Netview environnement when modification

[Jane Curry <jane.curry@skills-1st.co.uk>]

Many thanks for this, Bill.  I have put it on the NetView TUG site under 
"Config Management -> NetView FailOver mechanism".  The URL is:
http://www.nv-l.org/twiki/bin/view/Netview/ConfigMgmt

Feel free to modify / update it.  Note that anyone can make 
modifications that they contribute back to the community - the great 
thing about the TWiki mechanism is that it keeps older versions of pages 
so you can get various versions of contributions if you wish to.
Cheers,
Jane
