DNS Caching

(1/2) > >>

RetiredHal:
Hi,
I have some questions regarding DNS caching.
Recently I had problems getting on to a site (forum) that I frequently visit.
Typically there would be no response  from the site and an eventual 404 error.
If I tried the site a bit later or if I tried again after a power off/on or restart I was able to access the site.(usually)
Searching the internet I came across DNS cache settings in HKLM|System|CurrentControlSet|Services|DNSCache|Parameters
I run Windows XP  SP2 on a desktop and Windows Vista Home Premium SP1.on my laptop.
Both entries had a String value pointing to Windows|System32|dnsrslvr.dll.

Using a Hex editor I tried to make sense of what was “english” in the dll, but I readily admit that it did not make much sense to me

Inserting a value of Zero in MaxcacheTtl, MaxNegativeCacheTtl,NegativeSOACacheTime and NetFailureCacheTime, I feel that my “access time to the Site (and other sites) has improved, although it is hard to quantify.
The internet  does offer explanations, but I am still confused.

Q1, which set of doublewords belong to which version of windows?
Q2, If it does in fact improve “Hit Rate” why is it not standard practice to reduce the default settings?
Q3 What am I  trading off when I reduce the default settings ?
Q4. Can I , and Where in the dll file would I edit to play with values?

Thanks

NO, it is not spam.
It is a genuine question. I found this forum through Hero999 on another forum. If you dont like the question tell me why!
The fact that I may not know as much  about windows as you, or that I am not a programmer and  that I am basically an end user should not stop me from asking a question, (however stupid the question may seem to you).

The simple answer is that this is not a Windows help forum. Bill G makes lots of money selling his product. If it doesn't work for you, you should demand MS give you your money back or fix it. Why should we do charity work for billionaire who is to lazy or corrupt to produce a quality product and stand behind his work?

Thank You Davidnix71 for your reply.

I fully understand that this is not a MS  forum.  My decision to ask the question here is because after two days of enjoyable reading of different threads on this forum, I realised that despite the fiery  word exchanges, there are some very talented  and knowledgeable people here.

I posted in a thread that indicated that you might help if in trouble with a computer.

I have a feeling that if I had not mentioned windows and just asked about DNS zone entries, your response would have been different.

My questions (apart from the dll and  windows versions) really relate to dns /resolver architecture, and they are the same (I think ) for Linux,Unix or Windows.

The fact that I am a windows user is not because I like Mr Gates or windows.  I use windows like the other 95% of users because Linux  is not user friendly to an end user, my kids could not play the games they liked, they could not use messenger, Dual Boot (Grub I think) is a pain, I could not get my printer or  scanner to run  and when I  asked for advice when I had Ubuntu I was made to feel like a pariah because I had no programming skills.  That was 2 years ago, perhaps things  have changed and I may try Linux again  sometime.
The only thing that worked well was Gimp. Luckily, Gimp works equally well on Windows.

The last on my mind was to ask for Charity Work.
