Dont depoly from het sysvol\netlogon shares, create a new dedicated share for it.

Then it should work, using it here.

Yes, for some "stupid" reason, even MS is removing IE, we still need to add
The trusting zones.
trusting only a website with HTTP.
The second method would be along the lines of "*://hostname.primary.dnsdomain.tld ".
And the combination of the two would be along the lines of "*://*.primary.dnsdomain.tld ".

Yes, its all more restrictive.
Still not working.
try adding : acl allow execute always = true to the share.
if it then works, thens its a problem in the ACL's.
Then you might want to look in here.
In Internet Explorer, click Tools, and then click Internet Options.
Click the Security tab, click Local intranet, and then click Sites.
Clear the Include all network paths (UNC) check box, and then click OK.
Select the Trusted sites zone, click Sites, type the path for the download server, and then click Add.
Repeat the previous step for every download server that you want to specify as trusted.
Control Panel ?¨ Network and Intranet ?¨ Network and Sharing Center
Bottom left there is a 'See Also' section, click on 'Internet Options'.
Select Local intranet zone on the Security tab then click the Sites button
Click Advanced button, Enter file://[computer name.FQDN]
Make sure 'Require server verification...' is unticked
Last one i saw, i dont use this but it might help others.
Windows Registry Editor Version 5.00
