Hello

1. Access to Local Folders only: if your OutSystems Application requires to access local folders only, for reading and writing files, then grant all necessary permissions over that folder to the local group IIS_WPG (Windows 2003) or IIS_IUSRS (Windows Vista, 2008 and 7). This group includes the default users that run the OutSystems Applications, and thus access the files on that local folder. No additional user is required, but it would allow all applications to access the folder. If you want only a specific user to access that local folder, then just add your local user to the local IIS_WPG or IIS_IUSRS group, and grant the permissions  over the file system resource just to the local user instead of the group
2. Access to a Remote Folder only: if your applications try to access files, reading and writing, on a remote server (like a network share folder), then you need to have the same user credential to run your application and access the remote folder. There are two ways of doing this:

o    by using a domain user, recognized by both servers, and then add that domain user to your local IIS_WPG or IIS_IUSRS group on the OutSystems server, and grant necessary file permissions over the folder of the remote server to the domain user.

o    by using a local user on both servers, which have the same username and password (being like the same user in different servers, but with the same credentials), and again add the local user to your local IIS_WPG or IIS_IUSRS group on the OutSystems server, and grant necessary file permissions over the folder of the remote server for the local user created on that server

3. Access to a local and remote folder: this is basically a combination of the two above, where you should add your user (either local or domain) to the local IIS_WPG or IIS_IUSRS group on the OutSystems Server, and grant the necessary file permissions (reading and/or writing) over the local folder to the IIS_WPG or IIS_IUSRS group, and the remote folder to the user (either local or domain)

• Accessing the OutSystems Service Center on the OutSystems Server (either through remote or local browser using https://<serveraddress>/ServiceCenter, or locally using the Start Menu -> Programs -> OutSystems -> Service Center). Login using an administrative user and access the Factory section. In the espace list page, press over the espace that you want to access the applications and you’ll jump the its details page.
• Under the Operation tab, you’ll find input boxes for Run As settings. Just type in the local or domain user and password and press ‘Apply runas Settings’. Your application will now run under the chosen user credentials.
