When the store is configured with “Trusted Domains Only”, alerts may be logged in the Operation manager console stating that the Storefront Store Service Probe failed with Error description: "Could not get credentials"
More information can be obtain about the authentication attempt by enabling verbose logging on the StoreFront server:
- In the registry editor, open key HKEY_LOCAL_MACHINE\SOFTWARE\Comtrade\StoreFront MP Agent,
- Set LogLevel to "INFO".

The resulting log files will be located under ProgramData\Citrix\StoreFront MP Agent\logs on the Storefront server. The error below shows an "Incorrect Domain" error.
