Procedure to follow after major local network outage

After a major outage the many services run under Xen may no longer be functioning correctly.

Windows world

The most likely systems to be affected are the Exchange service and Verex. To restart Verex login to the server and restart the Verex service.

If exchange is not working the usual problem is that the store service has failed. You should start the Microsoft Exchange Information Store service on both svr-win-mta1 and svr-win-mta0. Then in the exchange system manager make sure the mailboxes are all mounted (expand server configuration and select mailbox then click on the server in the top pane) - if not right click on any un-mounted store and select mount.

If any machines are down then start them, the first to be started should be svr-win-db0. Apart from that there are no ordering constraints.
