| Event Information | Following Information from Newsgroup may help: --------------------------------------------------------------------- it sounds like the Link State check over a connector failed and the connector was maked as down for a while. Exchange 2000 tests connectors to ensure the route is available. If the test packets fail these events can be logged. The Link State marks the connector as down until it is retested, about 5 minutes. If this is happening often you may want to inspect the network route between these servers to see if packets are being dropped or something like that. --------------------------------------------------------------------- |
