SYMPTOMS
After you use the AutoDiscovery and Network solution in Microsoft Visio to rediscover your network devices, some devices may not show correct connections to other devices in your network diagram.



CAUSE
This behavior can occur if all of the following conditions are true, in the order in which they are presented:
 * 1) You perform a network discovery and create a network diagram.
 * 2) A cable change is made to a device in your network.
 * 3) You rediscover your network immediately after the cable change is made.
 * 4) You add the device (in which the cable change was made) to your network diagram.

When you rediscover your network immediately after a cable change is made to a device (or devices) on your network, Visio does not correctly handle the way in which layer-2 connectivity is related to layer-3 devices. As a result, incorrect information about the device (or devices) and their interconnectivity may be written to the AutoDiscovery database, and the device (or devices) may not show correct connections to other devices in your network diagram.



RESOLUTION
To work around this issue, delete the incorrectly connected layer-2 devices from your database, and then rediscover the devices. To do this, follow these steps:
 * 1) Start Visio, and then open your network diagram.
 * 2) On the AutoDiscovery menu, point to Database Viewer, and then click Open/Close.
 * 3) In the Database Viewer, double-click the device type to expand the group, and then view the device (or devices) in the right pane.
 * 4) Right-click the device that you want to remove, and then click Delete.

The device is now placed in the Deleted group.
 * 1) To permanently delete the device, double-click the Deleted group, right-click the device, and then click Delete.
 * 2) Point to Database Viewer on the AutoDiscovery menu, and then click Open/Close to close the Database Viewer.
 * 3) On the AutoDiscovery menu, point to Discovery, and then click Discovery Wizard to start the Discovery Wizard.
 * 4) Follow the instructions on the wizard pages to rediscover your network devices.



STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
