Thank you for your answer Lu-K.
I received your mail.
In fact i also submitted this issue (and dss logs) to serveral unix users group and all agree to try several "workarounds" accessing host and/or resolve and/or smb configuration files.
Don't misunderstand me, i am sure you are going to find a solution (if there is one on dss-side). I just mean that i would like to try on my own in order to exclude wrong assumptions one after another. Actually i am not even sure the problem is on adserver-side or dss-side.
That's why i need to edit these files..
Not "easily" possible right ?
