# Enable the Devolutions Server log files

You may be asked by our customer support team to get the Devolutions Server log files. They are located in the Devolutions Server web app App\_Data folder.

The files that are needed from this location the ones starting with "DPS\_Main" (**DPS\_Main\_001.log**, **DPS\_Main\_002.log**, etc.). If they are not present, it is most likely because the ***Application Pool Identity*** cannot write in that folder. Resolve this issue by giving this identity the ***Modify*** permission on the App\_Data folder.

### Enable log files

1. In the Devolutions Server Console select the desired server from the list.
2. In the ***Server*** tab click on ***Explore***. This will open the installation folder.

9. Wait for a few seconds and then click ***Start server***. Restarting the server will create the **DPS\_Main.log** and **DPS\_Main\_001.log** files after a short delay. Actions need to be taken on the Devolutions Server for logs to be created (logging in, etc).

{% hint style="info" %}
When granting the ***Modify*** permission to the ***IIS\_IUSRS*** group, all users of application pools on that server are allowed to access this directory. If the installation uses a specific application pool identity for Devolutions Server, consider giving permissions exclusively to that identity. Alternatively, you could assign ***Modify*** permissions to the NETWORK SERVICE account, which is commonly used for IIS application pools, though this account might be shared with other services as well.
