Web site can't connect to SQL server database

2 Web sites can't connect to SQL server databases. (There was no SQL server category so I listed this under MySQL). The Internet connection (and internal stuff) went awry and, now it's fixed, these two Web sites can't get the back end stuff they need.

I can give you (it would have to be supervised) access to the Web servers and database server. This is a small, quick job for somebody who has the right knowledge of making SQL server databases work with their Web sites.
