[Samba] Logon Script Sometimes Does Not Execute

[John H Terpstra]

David,

I can not see any clear reason for the intermittent problem. We would need
to capture an ethereal trace of a good and a bad logon to see what was
going wrong. I guess that is a tall ask, but that is all we are left to
explore if you are sure of the integrity of the physical network layer.
