The past couple of days I've noticed an unusually high CPU utilization from one of the svchost. Does anyone know if this is a known and unresolved issue? I've checked so many forums, blogs, etc. I tried the search function on this site but wasn't successful either. Please understand that Microsoft provides different support services which have different service levels and support boundaries.
Regarding this issue high CPU , it is necessary to collect related dump file to analyze the root cause. However, debugging service is out of our Forum support boundaries.
Thank you for your understanding. Disabling the DNS Client service fixes the problem, but then my web browser says it can't find sites. I have been fighting the hundred percent utilization problem for over two years on my laptop.
My wife has the same model laptop and has never had the problem, but I use more software and more high end software than she does. I have been to many forums and sites, found many "potential" solutions and tried some. Nothing worked. I was running Vista. I reloaded several times. The problem would come and go. Rebooted many times. Shutdown the computer totally and waited for a while. I upgraded to Windows 7, praying that it would fix the problem. No such luck.
I recently took note of the fact that the bottom of my laptop was very hot. I had vaguely noticed this before but hadn't paid much attention since it seems like it had always been that way. Then I started running experiments. In less than five minutes the CPU utilization started to drop. I took the fan off of it, put the laptop on a pillow to simulate my lap and watched the CPU utilization.
I did five or six variations of this experiment, always with the same result -- the CPU utilization rose with the heat and fell with the cooling. I had been chasing what I thought was a software problem but finally determined that it was a hardware problem. I thought it was associated with the WiFi component because it seemed to heat up more when I had heavy network traffic.
I like to know as much about a problem as I can before I call about it. I had gotten serious about fixing this problem since my extended warranty is running out in June, So I called Dell, and after the usual checks of this and that I usually have tried all those things before I ever call , the tech went off to talk to somebody. When he came back he wanted to know if I had a hair dryer I thought I've already gone through the heat tests.
But what he wanted me to do was blow out the grid covering the fan on the side of the laptop. I told him I could do better than that, I had a air compressor out in the garage that I had just been using and was ready to use. So I took my laptop out and in 10 seconds blew compressed air in all the openings on the laptop. A very small amount of dust came out of the grid and I thought "well, that's not going to fix the problem".
So I took my laptop back in, started it up, and everything was fine. The tech said he would call back in about half an hour to see how things were going. When he called back it was still running coolly and at very low CPU utilization.
I was a happy camper and still am. By visiting this site, users agree to our disclaimer. The members, admins, and authors of this website respect your privacy.

The reason you might want to change the time that positive responses MaxCacheTtl are cached for is this: in the 'old' days on the Internet, DNS entries were updated only twice a day, but today, most ISP's and domain name registrars have set their TTL Time To Live to 4 hours, so entries could change faster than before.
I have set my MaxCacheTtl time to seconds, or 4 hours. This is not the case! When present they will prevent Windows XP using the correct settings. By default, the resolver accepts responses even from servers it did not query. This could present a possible security liability, as an unauthorized DNS server might pass along invalid resource records to misdirect DNS queries.
