Yes, plan was to change IP, shutdown box, ensure DNS was sorted, WINS
was correct and restart.
Do ipconfig /flushdns , clear arp cache and see what happens!

Plan to do this while nothing is running, so intend to suspend backups
for now.

Also you may have to clear the arp tables on the servers and networking
switches. If you wait a few minutes they should timeout after about 5
minutes to an hour depending on the cache age settings for the CAM
tables. 
e.g. mac-address-table aging-time
default 5 minutes

Hi

Agree here, if you change the ip and keep the same hostname, depending
on DNS caching etc, it can take awhile for the NBU services to begin
communicating correctly with the host that had it's IP changed.  This
info is from first hand experience on quite a few master and media
servers.

VMWare can't give you a static or at least a reserved DHCP address?
