Storage Migration Service scans C$ to infinity

Copper Contributor

Hello everyone,

I've been trying to use the Storage Migration Service for the past few days, but I've run into a snag. The service seems unable to scan the C:\ drive. It just hangs indefinitely, whereas it scans the D:\ drive without any issues.

Here's what I've done so far:

- I'm using a domain account with the necessary privileges.

- I've installed all required services.

- All the necessary ports are open.

My goal is to migrate from a Windows Server 2012 to a Windows Server 2019 using an Orchestrator.

Has anyone else experienced similar behavior with the Storage Migration Service? Could this be a permissions issue? The servers were not initially set up by me but by the local admin, though I do have a domain admin account.

Any insights or suggestions would be appreciated!

Best regards,
