Hi, I am using Samba AD since last 2.5 years with 120 systems connected to domain services without any issues, but from last 15-20 days i am facing few issues with samba AD 1. Samba AD doesn't responds to RSAT windows tools & some times it works fine, but earlier it was working fine since the day it was installed. 2. On few of my systems i get "Trust relationship errors" while login & I have to rejoin the pc to work group and again have to join to my domain. Please suggest if anything need to be optimized at my end. Regards, Deepak
