When a number of people are modifying web content, you can use source control to see who is currently modifying a particular web document, identify any changes, prevent one author's changes from erasing another's, and revert to a previous version of a document, if necessary. To provide source control for a specific , you can choose the built-in source control or use an external source control program that supports FrontPage, such as Microsoft Visual SourceSafe.
Built-in source control is included with the FrontPage Server Extensions. You can use it to check in and check out a web, and revert to the last saved version of a web. Visual SourceSafe and other source control programs need to be purchased separately and installed on your computer. Typically, external source control programs can do everything the built-in source control does, plus they can track changes and revert to any of several previous versions of a web.
To enable source control
If you selected Use external, enter the name of the Visual SourceSafe or other project you would like to use.
Note
You can use Visual SourceSafe with FrontPage only if the Enable SourceSafe integration option is turned on in Visual SourceSafe. This is a custom installation option that you must select when you install Visual SourceSafe.
