Proper Setup Navision 2013 R2

Hello NAV Users,

Im currently trying to setup Navision 2013 R2 Three Tier Architecture.
Credentials setup is NavUserPassword

When im doing this credentials in Two Tier Archi, the NAV is working, but when im trying to do the three tier
navision can't connect.

My Question, what is the proper setup for NAV 2013 R2 using three tier and NavUserPassword?

Please help me guys!

Thanks!
