Hi All,
after other experiments, I finally installed a new W2K workstation and had
the same effect. But I found a machine, were it is working. And finally,
this a bit of blame for me, said to say, because after I upgraded this box
to have SP4 [!!!!!] everything works like expected. So, if one box is
involved in this type of connections, having not the latest SP [I have not
tried SP3 or others], produces the error. The other machines are more or
less from the "regular" environment, which are normally more actuel......
Thanks for the help guys and I am sorry for my bit of inaccuracy......I
really spent a lot of time with this issue.... :-(
Thanks and
best regards,
Manfred
