rpc:call on windows 2000

[micke]

I have a problem with getting two erl's talk on the same machine...

In dos-window one I do:
----------------------------------------------
D:\Program Files\erl5.3.6.3\bin>erl -name pong

(
)6> [node()| nodes()].

['
','
']


==============================================
In dos-window two I do:
----------------------------------------------
D:\Program Files\erl5.3.6.3\bin>erl -name ping

(
)21> rpc:call( '
', io, 
format, ['asdfasdasd']).
asdfasdasdok

(
)22> rpc:call( '
', io, 
format, ['asdfasdasd']).
asdfasdasdok


QUESTION: The call goes back to the same window, any clues on what the problem 
is ?
