Firstly, what recovery mode is your database in?
Are you performing any kind of backups at all?
Are you doing huge DML operations?
Do you have any open transactions (run DBCC OPENTRAN)?

Is .NET important for a database professional?

I have a server with SQL Server 2000 Enterprise Edition
with SP3A. The server has only one database on the
server. This system can have as many 200 transactions per
minute. Lately the database transaction log is growing
out of control.
What tools can I use to diagnose the problem and resolve
this problem?
Thanks,
Mike
