DNS Caching on W2K Pro-Workstation

I performed the following test:

- assigned to IP-Adress 18.1.105.10 the DNS alias "alias1"
- ping to alias responds with IP: 18.1.105.10

- assigned alias1 to IP-adress 18.1.105.12
- ping to alias1 responds with IP 18.1.105.10
- ping to alias1 from a machine which hasn't pinged alias1 before answers with the correct IP 18.1.105.12

Does Win2K write DNS-aliases into a lokal cache?
How can I turn off the caching?

-Check the hosts & lmhosts files on the local station.
-Perform clear the caches with nbtstat -R
-do an arp -d as well..
-try it again.. No go ?
-Clear the cached dns zones from the dns server mmc & copy the sample dns cache file to the servers cache file.

The cache is in memory. To clear it, use the
IPCONFIG /FLUSHDNS

(NBTSTAT is for netbios only, ARP is IP-to-MAC translation).

the ipconfig /flushdns works perfect. But how can I permanently avoid caching or set the time until refresh to a minimum?
