Exchange Online, but not able to access Web

I'm running Windows Server 2008 R2 Standard with Exchange 2010. Recently removed Sophos Anti-Virus and Pure Message as we were moving to different software.

The problem we have now is were not able to get anywhere on the web or connect to our D.R. appliance from that server. Exchange is still connected and emails are coming through just fine. We just can't get anywhere on the web, gives "Web page cannot be displayed" error. Pinging works fine, I've released and renew IP, DNS Flush, disabled Windows Firewall and still nothing. Using Firefox, resorted all defaults on that too. When opening up IE it closes right away.

Windows updates work correct and are up-to-date so i know it is connected. Any light on this would be greatly appreciated.

Thanks in advanced.

From the server try pinging the appliance by IP address.  Also try pinging something like cnn.com from the command prompt.  Let me know if either or neither get through.

It sounds like something with DNS then.  On your server, is DNS pointed to itself? (it generally should be).

For something to try, open up the properties of your server's network adapter, and change the DNS server from whatever you have it at now to "8.8.8.8" (one of googles servers) and see if you can browse.  If you can, then the issue is the DNS config.  If not, it's something else, and we'll need to keep looking.  Let us know!

If it was the Sophos AV client you removed, check through this and make sure you did all this:

What I find odd is the IE closing right away business.

Try going to some websites by IP address in Firefox.  If it doesn't work by IP address either, then we know it's either not DNS or not exclusively DNS.

I contacted Sophos and there are files in the registry that need to be removed (uninstalling them doesn't remove them) They were causing an issue with the DNS they said.

Thanks for all your help!

Most welcome!  Contacting their support was going to be my next suggestion :-)  I love Sophos, and use it myself on my own network, but uninstalling it can definitely be tricky.  Glad that did the trick!
