The message is
The log scan number (1166:312:1) passed to log scan in database
'master' is not valid. This error may indicate data corruption or that
the log file (.ldf) does not match the data file (.mdf). If this error
occurred during replication, re-create the publication. Otherwise,
restore from backup if the problem results in a failure during
startup.
Can you help in resolving the issue.
