Recently got the following alert
DESCRIPTION: SQL Server detected a logical consistency-based I/O error: incorrect checksum (expected: 0x03c8720b; actual: 0x887d3f27). It occurred during a read of page (1:73824) in database ID 2 at offset 0x000000240c0000 in file 'D:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\tempdb.mdf'. Additional messages in the SQL Server error log or system event log may provide more detail. This is a severe error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online.
Ran DBCC CHECKDB on all databases, no problems reported.
According to my colleagues no hardware issues are apparent on the server.
I'm unsure as to what I need to do next (very much a part time, 'accidental' dba)
Any advice appreciated.
