SharePoint Foundation 2010 List Workflow can't write to a file on a remote network host

Question

I have created a list workflow in Visual Studio which writes XML to a file on a network drive.

I have confirmed that I can access the drive from the SharePoint host. I can also manually create/modify/delete the file with my permissions.

When I try to execute the workflow from SharePoint (executed manually), I receive an exception stating that access is denied.

As I understand it, the SharePoint workflow should execute with the same credentials as the logged in user.

Is my understanding of the credentials used to execute the workflow correct? Do I need to have any special permissions set up for SharePoint itself?

Thanks.

Answer 1

The assumptions above were correct. The issue actually turned out to be network related (the workflow needed the FQDN of the target host for the export).

In my case, I was able to write the file to the network share (once the address for the remote host was corrected) without using SPSecurity.RunWithElevatedPrivledges or any other special changes.
