As always: It is the second Tuesday of the months and we released the Security Updates. However, this month is special from one perspective: We released an update for the DNS resolver, which is released simultaneously by a lot of DNS vendors with the same vulnerability. Here are some technical details about this vulnerability on the SWI blog: MS08-037 : More entropy for the DNS resolver . If you want to get some additional details on the vulnerabilities we fixed, the SWI blog might be a very good source: Security Vulnerability Research & Defense


  • I did the update and now my computer will not connect to the internet either with Internet Explorer or Firefox.  The connection is working fine locally, a router and DSL, and the other computer, which has not been updated, still connects to the internet.

    What happened?


  • Hi Duane,

    could you please get in touch with me by mail ( but it would have to be Thursday or Friday.

    It seems that we see certain problems with this update in conjunction with Zone Alarm. Do you have Zone Alarm on your PC? If yes, as a TEMPRORAY WORK-AROUND, set your security level to Medium. This should resolve the problem at the moment.

    As I said, this is a temporary work-around and we are looking together with Zone Alarm into how to fix the problem.


  • Hi Roger,

    Sorry being busy lately - but definately keeping an eye on all your posts.

    Apart from Zone Alarm, is there any other applications which will cause issues?

    Such as - Norton 360 and other security applications?



  • Hi Shoaib,

    at the moment we are aware "only" of Zone Alarm
