How to set one application per application pool?

Only one in-process application is allowed per IIS Application pool.

In Event Viewer, following error message is thrown:

“Only one in-process application is allowed per IIS application pool. Please assign the application '/LM/W3SVC/2/ROOT/Identity' to a different IIS application pool.”


Resolution:

  1. When checking Application Pools in Internet Information Services, multiple applications may be seen assigned to a single pool. i.e. Observe that UiPath Orchestrator pool has a number greater than one in the applications column. However, it should look like the screenshot below.
