We have three Samsung 400DXNs. We export reports out of SSRS in MHTML format. We copy those files to the local drives of each display every 15 minutes. We have a screen configured to display those MHTML files on a screen. This has all workd for 2 years. We added a new 400DXN this week and it will load the MHTML files the first time but as soon as the refresh interval is reached and it tries to reload the MHTML files we get a Microsoft popup asking for permission to load the tmp files.
I am sure this is a problem with the IE 7 sercurity settings but for the life of me we can not get it set right to resolve this issue.
Any ideas how to fix this or a better method to present this info.
