Upon upgrading form 3.3.7 to 3.5.1 I verified that certain devices were identified incorrectly because the file hostnames.ini was not being resolved correctly.
This had to do with the file being resolved in a different directory. Instead of resolving from \etc the 3.5.1 version resolves from E:\nic\csd\config\collectors.
The documentation was not updated and support and no knowledge of this issue. We ended up finding the resolution by checking the online help in 3.7.0.
