wyse Z90 W90 And approval problem

hello,
i've got a pb in my company only with the wyse z90 and w90 :
at the start of the wyse i've got this problem :
the relation of approval with the station and the domain has fail.

there's no double name machine (I test the SID).
i try to reset the count computer, it doesn't work to.

the only solution we have it's to outside the wyse on the domain and reintegrate the wyse.

it's a random problem sometime during three weeks no pb.

thank you for your help.
