Specified directory could not be found Parameter name: s:\company

SUGGESTED

So I am trying to use the Sage 50 API in a web application. The Web App will generate invoices and send them to Sage 50. Now the data is stored on another server at \\serverName\peachtree. I have this mapped to my S drive on the server and have that user configured to run my application in IIS. Now, network drives are a pain the butt apparently with IIS. I keep getting the error message "Specified directory could not be found Parameter name: s:\company " I was thinking that I could use the UNC path instead since I know I can access the drive using that. However, changing that in the PeachTree230.ini file did not work. I got the error message: "Object must be a root directory ("C:\") or a drive letter ("C")."

So I was curious if there is a way to get IIS to access the mapped drive or if there was a way to change Sage50 to access a data path via UNC. 

Either way, would work fine for me. I have spent a lot of time on this and am ready to be done with this.
