Hi John,
The steps below should help with this.
Add the MR connection path to the IE local intranet zone:
-On the user's machine, with Internet Explorer open, select Tools > Internet Options
-In the Internet Properties box, select the Security tab > Local Intranet > Sites > Advanced
-Add the Management Reporter connection path and click the Add button (for example: http://Servername)
**You can check the MR path in Report Designer under Tools -> Connection. Maybe even compare this path to working computers to make sure it is the same. IP addresses are not typically recommended.
-Close the local zone > OK > OK
Setting in IE:
-Go to Tools -> Internet Options -> Security -> Local Intranet
-From there, click on the “Custom level…” button.
-Then, scroll all the way to the bottom of the “Security Settings – Local Intranet Zone” screen and select “Automatic logon with current user name and password”.
-Click OK, then re-start IE and try again
