XCLN: Attachments Take Several Minutes to Open

If you try to open attachments, you may experience delays, up to several minutes.

This issue may occur when the duplex settings of the network adapters and the network switches do not match.

To resolve this issue, modify the duplex setting of the network adapter so that it matches the settings of the network switches.

To modify duplex settings of the network adapters, follow these steps.

NOTE: Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.

1. Click Start, point to Settings, and then click Network and Dial-up Connections.
2. Right-click the network connection that the Exchange server uses, and then click Properties.
3. In the Connection Properties dialog box, click Configure.
4. Click the Advanced tab, click Network Media in the Property list, and then click the correct setting in the Value box.

If the duplex settings on the network adapter already match the switch, make sure that other devices such as the routers have the same setting.
