Answer 1

Requests to your service are likely executing as anonymous, and the NETWORK SERVICE account needs permissions on the folder where your service is located to take whatever action your SOAP method requires (C:\MyFolder\, it seems.)

Add at least Read permission to that folder for NETWORK SERVICE. If you're doing any sort of I/O, you will likely need Modify permission as well.

Permissions setup on your service depends on the OS (Win2K3, Win2K8, Vista, Windows7....), so your mileage may vary.
