You can clear the WINS cache (NBT) by using the command prompt in a similar fashion as clearing the DNS cache:
Note that this only clears the cache. Normally you would want to repopulate it by running a new discovery (reregistration) on the network, like so:
When a backup is still indicated to run but isn't really (e.g. after a server crash or media failure), you can try to stop the backup by running the stop command using wbadmin (from an elevated command prompt):
wbadmin stop job

You can attempt to resolve the issue by re-setting the delivery location in your Accounts, but sometimes this does not work, and the delivery location remains unset. In this case, you have to create a new Outlook profile, recreate your e-mail accounts in it, set the delivery location and reopen any other Outlook data files.
