According to the database documentation (
View Database Documentation on the report editor), you want to link in
tblAssetComments. The field
tblAssetComments.Comment contains the "Renamed
xxx to
yyy" comments. If you add
WHERE
tblAssetComments.Comment LIKE '%oldname%'
to your report, you should find what you're looking for. Or it's something you need once-in-a-while, don't bother with the WHERE condition and just type the old machine name in the tblAssetComments.Comment filter box at the top of the report column.
