I built a Java plugin which runs a SQL script. This does a bulk load to read from xml files on a server, using a SQL login. To get it to work a SQL credential to a domain account was linked to that user. The remote servers were moved to a HyperV environment a few months back and ever since the bulk load fails, with the error 'Msg 4860, Level 16, State 1, Line 1 Cannot bulk load. The file "blah" does not exist.' I am told permissions would not have changed. What else could have caused this to stop working?
