I have noticed a problem with DNS lookups on my XP Pro machines, was a bit annoying getting failed lookups due to transient DNS issues, then the site would continue to fail to resolve after the DNS issue went away. That is when I would get host not found once, I would continue to get host not found.
Thought about it a bit and realized XP has NT & 2K's DNS Caching functionality (/joy).
I have added the following strings and values to [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dnscache\Parameters]
NegativeCacheTime = 0
NetFailureCacheTime = 0
NegativeSOACacheTime = 0
MaxCacheEntryTtlLimit = 1
Seems to have resolved the repeated failed lookup (when you bloody know its there) issue...Might try it if this grates on your nerves as much as it was mine...
If you totally didn't understand what I just said...Then you prolly shouldn't try it...
