I am looking for some help with DNS Scaveging. A little background..
1. We are Server 2003 with XP Professional laptops
2. Clients get an address from the DHCP servers
3. Servers have static IP's but do dynamicaly register (we have the "Register this connection with DNS" checkbox checked on each server)
Our issue is that we use our VPN to access other locations within the company (we are all laptops). As people hop from VPN to local network, we end up with multiple DNS entries for each user all with different IP's. We want to clean these on schedule, preferably a few times a day.
I tried this once before with a 4 hour scavenge and we lost a lot of server records. I know 4 hours is really short but since people bounce between networks all day we run into issues where they can't acess resources, etc., correctly as DNS is using the wrong A record.
So my question is....given this environment...how can I bet setup Scaveging? I know servers only register once every 24 hours right? Which would explain why I lost entries the last time. If there is no way to change that time period, should I uncheck the "Register this connection's address in DNS" for each server and only go to static DNS entiries for them?
Whatever happens, do not set the Refresh Interval lower than 24 hours. Clients with static IP addresses only update once a day, if they don't have the opportunity their records will be marked as stale and removed from DNS.
