# Application Reach Through - Troubleshooting

Error | Probable Cause | Solution
Cannot reach through to an element in the Administration Group. | Element has pre-MCD Release 4.0 software installed. | Upgrade element to MCD Release 4.0 or later software.
Form incompatibility. The requested form is not supported. The local element has a later software version than the remote element and the selected form does not exist in the software version on the remote element | Upgrade elements to same software version.
Form not licensed. Some forms, such as the FAX Service Profiles form must be licensed on the element before they are available. If a form is licensed on the local element, but not licensed on the remote element, you cannot modify it. | License the functionality associated with the form on the remote node.
The IP address of each remote element is missing from the Local Internet zone and Trusted Sites list of your Internet Explorer browser. The MiVoice Business Self-Signed Security Certificate is missing on the client PC. | Add the missing address(es) and certificate as required.
You are using Mozilla Firefox and the target element is pre-MCD Release 6.0 SP1. Reach Through in Firefox is only supported to elements running MCD 6.0 SP1 and later. | Use Internet Explorer 8 (or later) or upgrade element to MCD Release 6.0 SP1 or later software.
The Application Reach Through request fails. | User authorization profile is out of sync on the remote node | Use SDS to sync the User Authorization Profile form across the Administrative Group.
A network problem is preventing the local element from connecting to the remote element. | Contact your IT Support administrator.
You do not have permission to access the requested form on the remote element. The Admin Policies form is not synchronized across all the elements in the Administrative Group. | Ensure that SDS is sharing the Admin Policies form to all elements in the Administrative Group.
SDS was turned off and then on following a system reboot. Another reboot is required before Application Reach Through will work. In general, if access to a form is granted without a reboot , then others nodes cannot reach through to this newly granted form. To illustrate, consider the following example involving two switches, A and B: Switch A has access to Form1 but Switch B does not. Enable some licensing on B such that now B has access to Form1 but don't reboot. If a reach through is performed from A to B, there would be a reach through failure. After rebooting B, A can perform a reach through to B. | Reboot the switch the can't be reached.
Cannot find user on remote element. | The user information was not distributed to the remote element by SDS. | Resolve any SDS pending updates or errors on the local element.
After you select a remote element in the Show form on field and click Go, the browser does not open the form of the remote element. | IP address of the remote Administrative Group element has not been added to the Local Internet zone of the Internet Explorer browser on your client PC. | Add the IP address of the element.
