Hello. I have entered the following script that will create an excel report containing the users assigned to the project specified within the script. Note: This script alone, will create the report you are looking for if you are using a 32-bit OS. If you are using a 64-bit OS, please refer to the following EOT article (click the link below), which explains how to use a batch file to run a vbs file like this, on a 64-bit OS. 
[Batch file used to run a vbs file on a 64-bit OS][1]
To create the vbs file, you will need to open an instance of Notepad, enter the script that I have entered below, and save the file with a .vbs file extension. Before saving the file, be sure to edit the file to work in your environment. You will need to edit the server, domain, project, user, and password fields, along with the save location near the bottom of the script and the msgbox message that should display the save location for the Excel report. Once you have edited the script and saved your changes, double-click on the file to create the report. Once the report process is complete, you will be notified with a message box displaying such. I hope this helps.
