Resolved Connected but Internet Explorer doesn't work

I'm running IE 7 with the most recent updates from M$.
If I open IE I get page can not be displayed error.
If I manually enter a site, either by domain name or ip address, I get the same error.
But...
If I open Spybot and check for updates, it gets them, so I know I'm connected.

I've installed IE7 over itself and that worked...downloading updates and the program itself. Once reinstalled I tried to hit a website...same error.

I've run LSPfix and WinsockXPfix. Did not see anything unordinary in LSPfix and WinsockXPfix ran and did it's thing.

Any ideas at what to look for or to do?

I did gather this from another post. Should I try this?
2. Clear all TCP/IP possible issues!

Drag mouse with left button down across the each line below then rt click and copy then paste each line below 1 at a time to an open CMD prompt and hit enter, depending on your setup you may get errors, ignore any errors for now.
----------------------------------------------------------------------
netsh interface ip delete arpcache

ipconfig /flushdns

ipconfig /release *

ipconfig /renew *

ipconfig /registerdns

nbtstat -RR

netsh winsock show catalog > "%USERPROFILE% "\Desktop\lsp.txt

netsh winsock reset catalog

netsh winsock show catalog >> "%USERPROFILE% "\Desktop\lsp.txt
----------------------------------------------------------------------
After the last netsh above there will be a new icon on desktop (lsp.txt). Post this back!

Reboot

 

I am writing this reply through Mozilla's Firefox browser!
I can access websites with this browser yet IE7 still returns "Page cannot be displayed" error.
Where do we go from here?
I've ran Spybot, Adaware, SuperSpyware, XoftSE and nothing turned up.
I did just go into Windows Firewall blocked exceptions list and notice IE wasn't listed.
I added it but still can not connect.
I am editing my original reply via Firefox.

 

Situation solved!

OK, scratch this thread. Problem solved.
Believe it or not, your asking me to try Firefox and having it work made me think. You can see in the last message I thought maybe Windows Firewall was blocking it. It ends up it wasn't.
I hunted around somemore and looked into McAfee's firewall.
Sure enough, IS was blocked - don't know how it happened but I'm sending this message via IE7.
Live and learn.
Thanks.
