103. Improve DNS resolution.

If you would ask me how XP handles DNS resolution, I would have to admit that it is simply
great. But there is still a room for improvement. This can be done by increasing the DNS
Cache size. To do this you would have to add following entries in registry. Please navigate to:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters.
Create or modify (if already present) the following four DWORD keys to following values.

CacheHashTableBucketSize 00000001(hex)
CacheHashTableSize 00000180 (hex)
MaxCacheEntryTtlLimit 000fa00a(hex)
MaxSOACacheEntryTtlLimit 0000012d(hex)
