I have a small web service, which should send faxes. The code for this web service is working fine when it is not in the wwwroot folder. However, once I add this service to the IIS, I always get FaxDocument exception when I call that service. I think the problem is in the permissions somewhere. Can anyone suggest how can I configure my web service to use the FaxComExLib library? What permissions should I set?
