Our SSRS server is not executing a subscription correctly. (Only subscription we have btw)
We created a subscription to export a report as an excel file to the file system.
Tried running the job that gets generated, and this error happens
'EXECUTE AS LOGIN' failed for the requested login 'NT AUTHORITY\NETWORK SERVICE'. The step failed.
It's not the most helpful in tracking down what exactly it was trying to do.
EDIT
Digging further into the logs I also get these errors
