Pro version of HTML Link Validator can check links in MS Access database.

To validate links in MS Access database:

1.
On the left plane of the main Link Validator window select file filter "MS Access Database (.mdb)"

2.
Double click on the database file (on the screenshot below the selected database is db1.mdb)

3.
HTML Link Validator will display another window asking user for a table name and a field name that should be validated. On the screenshot below the table name is "links" and the fiels name is "My_Site_Links".

You also should specify how the links in database are recorded.

Two formats are allowed:
  each record can contain "pure" URL (like http://lithopssoft.com/index.html)
  or record can contain tag, like this: <a href=http://lithopssoft.com/index.html ...>
but the format must be the same for all records of the field.

Click "Go" to start validation.
