There has been a story starting to brew about a serious DNS security flaw. The details of the flaw have finally been leaked here:
Information Week ArticleThis is one of those problems that is easy to ignore, but could become a huge nightmare if left unchecked.
Essentially the flaw allows an attacker to redirect clients to a different IP address for a particular domain.
For example, when you go a website (Lets take www.chase.com as an example) the domain name is translated into an IP address. In this case that IP address is run by Chase and responds to your request. When someone exploits the flaw they could redirect www.chase.com to go to their server, and present a fake login.
This is a simple example, and the possibilities are much worse than that. Imagine an attacker redirecting *all* of your traffic through their server. They could then use this opportunity to push spyware to you with every page you visit.
Many of you may not have a choice, since your DNS may be run by your ISP, but if you are running Windows based DNS servers, I suggest installing the patch as soon as possible:
Microsoft DNS PatchI wish I could say the patch works flawlessly, but some clients of ours have reported that it has caused issues with Active Directory. Still...most of these problems are far and few between and are usually due to an odd configuration...such as having a domain controller with 127.0.0.1 as its primary IP address.
So with that in mind I would make sure you deploy the patch after hours and do lots of testing.
One more thing - you can test your DNS server for the flaw by visiting
http://www.doxpara.com/ on the right there is a button that says "Check My DNS" It will tell you if your DNS server is vulnerable to the flaw.

Many people face this problem “
steam://purchase/38 is not a recognized protocol” when they try to purchase anything from the steam store. But
Farid brought a fix for the same problem. Here is how you can fix the steam protocol problems in Windows Vista.
The problem lies within Vista’s registry security settings. I am writing this from memory (I don’t have Vista myself). Here’s how to fix it:
1. Using Vista’s start menu, type “regedit” in the run field to start the registry editor.
2. Browse to the “HKEY_CLASSES_ROOT\steam” key. If you are having the problem you will notice that you aren’t able to view the key content
3. Right click on the “steam” key and click on “permissions…”.
4. You will notice that no user is listed under “Allowed users”. Add the following users/group and give them full access: Administrators (group), System (user) and your own user name.
5. If you press Ok, it may complain that you are not the owner and aren’t allowed to do this. In this case simply click on Advanced and add the above users as owners and try step 4 again. I only added System as owner and that did it. (You may need to close the permissions window and reopen after assigning owners)
6. That’s it! You now should be able to see the content of the key but it may be empty. In this case re-install steam and you should be good to go.

SanDisk said Monday that Windows Vista is not optimized for solid-state drives, delaying the delivery of optimized drives until next year.
Solid-state drives (SSDs) are used instead of hard disk drivers in select high-end noteboo PCs today such as the Apple Macbook Air and Toshiba Portege R500.
The next generation of SSDs will use multilevel cell (MLC) technology, which will require a more sophisticated controller--a crucial component in solid-state drives. These drives will have capacities ranging up to 128GB, 160GB, and later, 256GB. MLC drives are expected to appear in a wider selection of notebook later this year.
Speaking during SanDisk's second-quarter earnings conference call, Chairman and Chief Executive Officer Eli Harari said that Windows Vista will present a special challenge for solid-state drive makers. "As soon as you get into Vista applications in notebook and desktop, you start running into very demanding applications because Vista is not optimized for flash memory solid-state disk," he said.
This is due to Vista's design. "The next generation controllers need to basically compensate for Vista shortfalls," he said.
"Unfortunately, (SSDs) performance in the Vista environment falls short of what the market really needs and that is why we need to develop the next generation, which we'll start sampling end of this year, early next year," Harari said.
Harari said this challenge alone is putting SanDisk behind schedule. "We have very good internal controller technology, as you know...That said, I'd say that we are now behind because we did not fully understand, frankly, the limitations in the Vista environment," he added.
In the very low-end of the market, however, this is not an issue. "In very low-end, ultra low-cost PCs, existing controllers can get the job done for 8-, 16-, and 32-gigabyte storage because these are relatively unsophisticated and demanding requirements," he said.
SanDisk has a production joint venture with Toshiba, which also makes solid- state drives.
