Internet Explorer zone mapping group policy

Dear all,

I've been searching for days to find out what is wrong with my internet explorer zone mapping group policy.

I have the following trusted sites. (If it says local domain or local server I have added this manually in this thread to be more specific.)
Can anyone tell me what is wrong here?

Also I tried adding 192.168.41.1-253 as en entire range but that didn't work, even though suggested by Microsoft. That's why I have re-added all the other 192.168.41.x addresses. These are mostly file servers.

Many many thanks!

Hi Carl,

I have already read your topic. In fact, I'm the one that asked the question about file:\\1.2.3.4 and file :\\servername (Joachim) :)

But the group policy keeps throwing errors on the zone mapping and I can't find what is wrong.
Carl WebsterCitrix Technology Professional - FellowCommented:
In that case, you will have to do what I originally did; try one entry at a time in a test gpo and see which one (s) is not acceptable.

Thanks!! I have finally found the culprit!

I should have seen it before but I never thought it was wrong.

I had an entry *://*.sd.be which is the domain of a website called SDWorx.
Internet Explorer thinks this is a top level domain like .co.uk so it threw an error.

Removing it fixed the issue.
