Hi I finally fixed my issue all I had to do on my C# code I had to force the mapping of my shared folder. Its weird because the first time I used the service for the first time I didn't for it to map. But after changing the Shared folder to a different drive that's when i had this issue.
Below is the C# code to force the mapping.
oNetDrive.Force = true;
oNetDrive.Persistent = true;
oNetDrive drive is the Shared folder. Force and Persistent are the properties.
