Agent isn't working in Win 10

Agent isn't working in Win 10

Our desktop build version is 10.0.56 . Most of the win 10 os are always offline even though we installed agent properly. But the other os such as win 7 and xp are working well.if we reinstall it , it can be seen online for few hours.A few hours later , it's offline again .

Somebody can help this problem.Thanks in advance.
