DNS scavenging on an edited Host record. (Lots of points)

I was wondering if I edit a host record in DNS if that record will be scavenge if there is no physical machine with that name to update the record? What I have is a service that is tied to a server name. Some of my clients are tied to ServerA and some to ServerB, I want all of then to hit ServerA. However, I don't know which ones are pointed to ServerB and do not have the resources to look on all the clients and change the setting manually. What I was wanting to do is to edit the existing host file for ServerB to point to the IP address of ServerA so that I can take ServerB offline. My concern is that the record will be scavenged after seven days if there is no physical machine actually updating the record. Please answer if you for sure know the answer or have done something like this before. Thanks.

I can tell you for a fact that I have had an entry called PROXY in my DNS server for the past 2 years and there is no physical machine by that name on my network.  I use it to point to a server where I need a different name for a proxy service....  :-)

scavenge does do anything to STATIC records, you will be Ok.

restated: scavenging does NOT effect static entries in DNS.
