[Samba] Long time before user shows up on member server

[L.P.H. van Belle]

Something in the DNS resolving is off. 

Can you run the following script on all the AD-DCs.
and the problem Member server. 
If you anonymize it, keep the setup structure the same. 
Like netbios name = HOSTNAME_CAPS_OR_NOT  
or if realm = internal.domain.tld  , use INT.REALM.TLD  
we need exact as it.
