Storage Migration Services - Check if the source device is online - we couldn't access

Copper Contributor

Hi,

I am transferring files from a Windows 2008 R2 servers to a Server 2019 server. It transfers about 6,000 files, then stops with this error: Check if the source device is online - we couldn't access it.

I have rechecked the prerequisites and they are fine.

I am a domain admin, and in the local admin group on both servers.

The 2019 server is build is 10.0.17763.

From the event log:

Couldn't transfer all of the files in the endpoint on the computer.

Job: Jobname
Computer: source computer
Destination Computer: computer
Endpoint: something
State: Failed
Source File Count: 0
Source File Size in KB: 0
Succeeded File Count: 0
Succeeded File Size in KB: 0
New File Count: 0
New File Size in KB: 0
Failed File Count: 0
Error: 40961
Error Message: Transfer failed

Guidance: Check the detailed error and make sure the transfer requirements are met. This could be because the orchestrator computer couldn't reach a source or destination computer, possibly due to a firewall rule, or missing permissions.

Any help would be appreciated!

Thanks
