What do I do if my FrontPage counter resets to zero?

You can modify the counter file. It resides in your _private directory. Use the FrontPage Explorer to open your site and access the file. Right click the file and open it with notepad. (it's the file that ends with .cnt, as in counter) When you open the file you should see something like this:

FPCountFile 00000004598

Put whatever number you want, but make sure that you don't change the amount of digits currently there.
