Latest Microsoft Update - now I can't connect to internet (DNS) (1GB, server)

[chielgirl]

Didn't know whether to put this in computers or internet, so here I sit.

Microsoft pushed an update about a week ago and now I can't access the internet without going back to an older version.

Is anyone else having this problem?
Any solutions?

Try disabling your firewall momentarily, see if it helps the issue.

Try alternate DNS servers, such as Google Public DNS or OpenDNS.
Google Public DNS
OpenDNS - Cloud Internet Security and DNS

Are you sure its DNS? You can try flushing your DNS cache as well.

type "IPConfig FlushDNS" at a command prompt. Capitalization doesn't matter. Check your HOSTS file, see if any alterations have been made that you didn't make yourself.
HOSTS is located in C:\windows\system32\drivers\etc\HOSTS.
Open it with notepad or similar. If you haven't made any alterations, you should see "127.0.0.1 localhost." or similar.

That's also a handy tool to fight advertisements.

Bitdefender's Firewall has given me problems in the past. Their stealth-mode for the network adapter has prevented it from properly registering. A simple solution was to turn off stealth-mode for each adapter through Bitdefender's firewall.

I've also had problems with Norton leaving behind a firewall filter driver on the network adapter after uninstalling Norton software. Easiest way out of that one is using Norton's uninstall tool.

Need a wee bit more information.

Version of Windows
Error messages or symptoms
What do you mean, exactly by "going back to an old version"
How do you connect to the internet.

I'm using Windows 7 on an Acer One. 1GB RAM
Error message starts with DNS
I went back to a 10 January 2011, pre-most recent update and things work pretty fine. (I think I reverted to an earlier date)
I'm connecting via wireless.

Konraden, thanks, I'll give it a try.
Am in internet cafe at the moment and may have to check some things with iPhone connection.

Thanks, will be going back to my room soon to check this out.

Posting from my Acer.
Still giving DNS errors, but if I go back to the last page, I seem to be able to get to where I want to be.
Will keep you apprised of progress.

Thanks,
I flushed the DNS from the command line.
