There are most of the time when you browse to a website through your computer's default browser, in this situation your computer to sends an information back and forth, which is obviously done. From this information it deals with resolving the site name to an appropriate IP address, these are the stuffs that tcp/ip really deals with it. This is a DNS information and it is used so that next time you will not need to ask for the site location every time when you visit the site. Although Windows XP and Windows 2000 has an efficient DNS cache, you can increase overall performance by increasing their size. This can be done by the registry entries.
You need to do the following methods as mentioned below:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters]
"ServiceDll"=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,\
00,74,00,25,00,5c,00,53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,\
64,00,6e,00,73,00,72,00,73,00,6c,00,76,00,72,00,2e,00,64,00,6c,00,6c,00,00,\
00
"MaxCacheTtl"=dword:00002a30
"MaxNegativeCacheTtl"=dword:00000000
"CacheHashTableBucketSize"=dword:00000001
"CacheHashTableSize"=dword:00000180
"MaxCacheEntryTtlLimit"=dword:0000fa00
"MaxSOACacheEntryTtlLimit"=dword:0000012d
You need to make a new text file and then rename it to "dnscache.reg". After that copy and paste all the above into it and save it. Finally merge it into the registry.
