CacheHashTableSize to increase size of DNS resolver cache

Does Windows 7 and Server 2008-R2 support editing the following registry
values to change the DNS resolver cache size?

CacheHashTableSize
CacheHashTableBucketSize

I've tried playing with these, but the cache size never changes. Another
person got the same result
(http://blog.mischel.com/2008/06/11/c...esolver-cache/).

So are these values hard-coded now? Or is there a different way of changing
the resolver cache size?

THANKS!!!

Anyone know how to increase the size of the host name cache in RAM so that
more entries are listed when you run "ipconfig.exe /displaydns"???

Thank You!
