Need Help w Batch Rename

[MikeInThe901]

Thousands of files in a folder w following 2 base names. Within each name all files are consecutively numbered, and some also have an 'a' or 'b' after the digits.

Smith_0002.jpg
Smith_0002a.jpg
Smith_0003.jpg
Bill_1001.jpg
Bill_1001a.jpg
Bill_1002.jpg
Bill_1003.jpg
Bill_1003a.jpg

Can't I use the REN command w wild cards to change the filenames beginning w Bill, to end up with this:

Smith_0001.jpg
Smith_0002.jpg
Smith_0002a.jpg
Smith_0003.jpg
Smith_1001.jpg
Smith_1001a.jpg
Smith_1002.jpg
Smith_1003.jpg
Smith_1003a.jpg

Thanks!
