Resolution

Disable ASP.NET Impersonation for the website were Archer is installed by following the steps below:

3. Then in the middle pane, double-click on Authentication.
4. It should be observed that ASP.NET Impersonation is enabled, as shown in the screenshot above.
5. If it is enabled, click on ASP.NET Impersonation and then click on Disable from the right pane (another authentication method should be enabled which depends on the type of authentication you have setup).
6. Following this, users should be able to upload attachments into Attachment fields successfully.

Note: The above checks and steps should be followed and performed on all Web Servers.
