Console application service written in C#

Hi,

I have written a console application service in visual studio 2015 and installed/run it on windows server 2012. The service has a timer that should trigger a method in the code at a exakt time point. It runs and trigger the code at right time in the first day but on other days it run/trigger the code att three or four other time too. This type of code/service run on a windows server 2008 very good but not on a windows server 2012.

Does any body knows anything about this problem? does it depend on thread logic on the operative system of win 2012?

Regards
