Synthetic Web Transaction Monitoring question

Hi All,

I have my SCOM in Domain A. I need to monitor transaction on a URL which is hosted in Domain B and can be access only through Domain B. I have a SCOM Gateway server in Domain B.

I have created a Web Synthetic Transaction Monitor in My SCOM with Watcher Node as the Gateway server in Domain B to record the transactions on the URL that is accessible only from Domain B and not domain A.

When I run the Test after creating the Transaction Monitor I get the result as Error Code 403 (Forbidden Access).

Can anyone please let me know how can I achieve a successful monitoring in this scenario. Do I need to use an Authentication method?

Thanks, S K Agrawal
