Azure DataFactory File System Linked Service is not working with this error:
Error details Error code 28051 Details c could not be resolved.
I tried to connect file excel in onpremise machine using the self hosted integration runtimeg
Appears that ours auto-updated on 11/11 and it hasn't worked since then for connecting to C drive like it has.
But I've fixed this for myself. have change the Host from c:\ to \\servername\c$ and now testing the connection is successful.
