From the Project Node, opened on your project node you should see a directory of folder named drive:\Inetpub\wwwroot\broadweb.
1. Start Windows Explorer (Right Click on Start -> Explore).
2. Browse to the Broadweb folder. Typically it is located at C:\Inetpub\wwwroot\broadweb
3. The deploy file should be listed there (projectname.dpj).
If you can not open the folder or it does not exist, then the Directory Security on the folders in drive:Inetpub\wwwroot are set to either read only or other setting that prevents the web access software from creating the deploy file.
