# How to cache credentials for access to Network Storage and verify Read/Write access

**Cache Network Storage Credentials**

In order to configure a Windows account with persistent access to Network Storage locations, it is necessary to cache the network storage credentials within the Windows account using the following steps.

1. Login to the instrument using the Windows account(s) which will be writing to network storage (typically **sbsuser**).
2. Open **File Explorer** and enter the network output location (in UNC format) into the address bar.\

3. Enter the credentials of the desired user who has access to the desired network storage location into the Windows Security prompt. You may need to work with your IT team for assistance with these credentials.
4. Select **Remember my credentials**, then select **OK**. This will add the network storage credentials to the Windows **Credential Manager.**\

5. Open the **Credential Manager** application in Windows. Verify that the credentials entered above have been cached to in the Windows Credentials. **Note**: If these credentials change, the cached credentials must be updated in order to continue output to your network storage. ![](/files/rXtpb6eIP0pJFFcacZM8)

**Verify Write access to Network Output Location(s)**

1. In Windows **File Explorer**, right click within the intended Network Output location and select **New** > **Text Document** to create a new document called test.txt. ![](/files/3aftlqu767qvv5f7rACc)
2. Delete the file just created.
3. If either of the actions above fails, your account does not have write permissions on the Network Output location. Work with your IT team to configure the Network Output location with appropriate permissions.
