Error 0x800703e6

I just installed MSE and when it runs it says it has to update the definitions and when it tries to run through the update it gives the Error 0x800703e6 and says there is no internet connection which is not the case.

I have no other virus applications running or installed.

Auto updater service is started along with BIT service.

Any advice?


Last thing to try before you open a support case:

Open IE, go to Tools/Internet Options/Advanced and click the button to reset to default.

Try the update again.

If that doesn't work - support is the way to go and please let us know the outcome.
