SQL Server 7.0 won’t start

I’m new to SQL Server, and I have SQL Server 7.0 installed on my NT 4.0 SP6 server. Whenever the service attempts to start, it fails and leaves the following entry in the Event Viewer: “Database ‘model’ cannot be opened. It is in the middle of a restore.” I’m not doing a restore, or even a backup. What can I do to either fix this database or tell SQL Server not to open it when the service is started?
