Hi,
As Pete said, the libNetx.so client lib is not build (yet) on Windows.
Enabling this is on our todo list, but it was not given the highest
priority, as nobody asked for it so far.
We do not expect particular problems with netx on Windows, but it needs
to be tried and tested. To my knowledge, nobody has tried to build on
Win32GDK.
I will try to make at least the basic tests soon, so that interested
people can start testing.
Gerri
ps:
1. giving explicitly the port number in the url should not be
necessary if you add the following line to /etc/services
rootd 1094/tcp # ROOT daemon
2. to avoid loading explicitely libThread.so before libNetx.so
create the 'rootmap' executing 'gmake map' after 'gmake'.
(This is something introduced recently to avoid an
'explicitlink' with all the libraries as basically done
before).

What does the "matching protocol not found" mean in the xrootd log file? What protocol is it talking about - perhaps an authentication protocol that I need to configure?
