There are issues with services distribution when you have more than one server with IIS (right now I have two of them) and since OS provider and Web provider are located on different DNP Server instances and they have different IDs in DNP Enterprise DB service distribution is broken. Latelly I have to change ID for FTP provider because all services are being created on first server and FTP on second. I've already described this problem to Andrey. I've created this thread to find people which have similar DNP configuration like mine to confirm this issue.
P.S. I've forwarded you two e-mails which was sent to Andrey describing this issue.
