What to do with this please explain step by step i saw this in a mag it says fine tune internet access speed
by saving this

"CacheHashTableBucketSize"=dword:00000001
"CacheHashTableSize"=dword:00000180
"MaxCacheEntryTtlLimit"=dword:0000fa00
"MaxSOACacheEntryTtilLimit"=dword:0000012d

in HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Dnscache\parameters
PS Vishal the registry Whiz where are you

here are the steps:
1) goto start>run and type regedit
2) Browse to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Dnscache\parameters
3) Create 4 DWORD values and name them as
CacheHashTableBucketSize
CacheHashTableSize
MaxCacheEntryTtlLimit
MaxSOACacheEntryTtilLimit
4) Modify the values to
1
180
fa00
12d
Respectively
(don't forget to select hex)

you're done

Alternate solution:
open notepad and punch in the following lines

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\Dnscache\parameters]
"CacheHashTableBucketSize"=dword:00000001
"CacheHashTableSize"=dword:00000180
"MaxCacheEntryTtlLimit"=dword:0000fa00
"MaxSOACacheEntryTtilLimit"=dword:0000012d

Save this as dns.reg (be sure to select "all files" in save dialog box). double-click this file and you're done.

@kill
dude he is asking what those values do...i.e. how they work.....

All these options r used to increase DNS performance!
Whenever u visit any site, windows cache the DNS information and thats why these options r used to speed up DNS caching.

"CacheHashTableBucketSize" => It specifies no. of columns that the Hash table can contain in DNS Cahe.

"CacheHashTableSize" => Same as the previous option, It specifies no. of rows that the Hash table can contain in DNS Cache.

"MaxSOACacheEntryTtlLimit" => Its used to specify how long SOA (Start of Authority) record can remain in DNS cache.

"MaxCacheEntryTtlLimit" => Its just the opposite of the "MaxSOACacheEntryTtlLimit" option, as u can see the difference in their names. It specifies how long a DNS record other than SOA can remain in DNS Cache.

Thats what I can explain about them

doesn't it look like he wanted steps?

anyways the values are straight forward
CacheHashTableBucketSize Modifies the no. of clolumns in DNS cache
CacheHashTableSize Modifies the DNS cache table's size
MaxCacheEntryTtlLimit Modify Time To Live of a DNS cache entry
MaxSOACacheEntryTtlLimit maximum time that an SOA (Start of Authority) record can remain in the Domain Name System (DNS) cache


edit:
@vishal: seems like we posted on nearly the same time, lol
