    HI All,
    I have a suspect database which regularly goes into suspect mode. BUt when the server restarts it comes online again and after some time it goes offline again.
    First Request: Let me know what are the possible ways to get the suspect database to online mode.
    2) what could cause that database to go in to suspect mode.
    3) how tp find the root cause.

    Resets the status of a suspect database.

    sp_resetstatus [ @DBName = ] 'database'

    [@DBName =] 'database'
    Is the name of the database to reset. database is sysname, with no default.
    Return Code Values

    0 (success) or 1 (failure)

    sp_resetstatus turns off the suspect flag on a database. This procedure updates the mode and status columns of the named database in sysdatabases. The SQL Server error log should be consulted and all problems resolved before running this procedure. Stop and restart SQL Server after executing sp_resetstatus.
    A database can become suspect for several reasons. Possible causes include denial of access to a database resource by the operating system, and the unavailability or corruption of one or more database files.

    Only members of the sysadmin fixed server role can execute sp_resetstatus.
    If it works, then run DBCC Checkdb to find out if there are some problem.

    That is not good for making a database suspect each and every time.
    Look at SQL server error log, event viewer log and all other logs that could give some information on why this database is becoming suspect. Also check the disks are in good condition.
