If the Pharos Server was built on a Non-English OS, and then changed to English US, this will occur.
The reason is that Services running on the server will use the Local System Account to run by default. This includes Pharos. As such, they are still using the Non-English settings. This is occurs due to the way that Microsoft Windows works, and can not be changed once built this way.
Pharos MUST run in this manner once a system has been built on an OS other than English US.
