Well, after a few days of checking and testing we'd found out 2 ways to solve the problem:
- dllhost.exe.config - should not be edited/created/updated manually,but from MSI.Probably the reason is that is is placed at system32 directory and windows blocks it.
Better way - is to create for COM+ Service Application Root Directory and place there 2 files
- ServiceName.config - Contains list of endpoints
- ServiceName.manifest - Contains 3 rows
