This article describes how to install and use the WinRoute tool.

Back to the top

The WinRoute tool connects to the link state port (TCP 691) on a server that is running Exchange 2000 Server or Exchange Server 2003, and extracts the link state information for the Exchange organization. WinRoute presents link state information in its original format.

Installing WinRoute

To install WinRoute with Exchange 2000, run the Microsoft Exchange 2000 Server Resource Kit Setup program. You can also install the tool by following these steps:

1.	Insert the Microsoft Exchange 2000 Server Resource Kit CD-ROM and locate Exreskit\Tools\Admin\WinRoute.
2.	Copy WinRoute.exe to the Program Files\Exchsrvr\Bin folder on your local disk. The following .dll files must be present in the Exchsrvr\Bin folder (these files should be installed when you install Exchange 2000): • Dsaccess.dll • Pttrace.dll • Exchmem.dll

Note You can also find WinRoute in the Support\Utils\i386 folder on the Exchange 2000 Server CD. For Exchange Server 2003, visit the following Microsoft Web site:

How to Use WinRoute

1.	Start WinRoute.exe.
2.	On the File menu, click New Query.
3.	Type the server name and bind options that you want to use to connect to an Exchange 2000 server.

In the upper half of the WinRoute window, the formatted link state information is displayed; in the lower half, the unformatted information from the link state port is displayed. In the upper pane, there is an expandable object that is named General Info. This object contains the routing engine version, digest, and organization information, and it contains expandable objects for each routing group in the organization.

Important To determine the current size of link state data for the organization, copy the information from the lower pane, and then paste it in a Notepad (.txt) file. The size of this new file is equal to the size of the link state data.

You can use WinRoute to view the routing groups and the Major Version attribute that identifies the current sequence number for the routing group. You can also view the status of each connector. If a particular routing group has a version number of zero, link state information from that routing group's master has not yet been received. In this case, the two servers synchronize link state information by comparing the GUIDs that are associated with each routing group.

To save the information that is displayed by WinRoute, click Save As on the File menu. Save this file with an .rte extension so that it can be opened remotely by WinRoute.

Troubleshooting

If the screen is blank after you start WinRoute, the Routing Engine service (RESvc) may not have been initialized or started. If this is the case, make sure that RESvc, the SMTP service, and the MSExchangeMTA services have been started. You may also want to send a message to the SMTP engine to verify that the component is working.
