That depends on why the database is suspect.
Please take a look at the SQL error log. See if you can find anyy message indicating why the DB has been marked suspect. There should be something in there.
Have any changes been made to the server just before it went suspect?
Are the data files where SQL's expecting to see them?
Do you have a recent backup?
