Script works from server but not from website

Good afternoon,

I'm having running a PowerShell script from SAM.  It's looking for any file that's over 30 minutes old in a given folder hosted on a fileshare, in case that's relevant at all.

When I run it from SAM, it tells me that the folder doesn't exist, but when I log into the poller and run the script from there it returns values just fine.

I'm using the same set of credentials, I verified it's running from the poller I tested, what else should I double-check to see if I can get this script working?
