Maybe C-g put the server in the "denied" state; Gnus will not try to
open a denied server.  You can type ^ in the *Group* buffer to reach
the *Server* buffer.  Then type C and O on the server to close and
open it.  Then type q to exit the *Server* buffer.

This does not prove that the server is not being put into the "denied"
state.  It's true that the first hang still needs another explanation,
but if you check the *Server* buffer and see that the sever is denied,
then closing and opening it will save you having to restart Gnus to
recover, assuming you can get your connection back up in the meantime.
The fact that you still can't contact the server even after the
connection comes back strongly suggests that the server is denied.

I see. This works.

The server then (i.e. when Gnus went to the "dead" state as described 
previously in the thread) looks like this:

     {nnfolder:archive} (opened)
     {nndraft:} (opened)
     {nntp:news.space.net} (opened)

This means, that the news server is not in "denied" state.
Nevertheless,
it can't re-connect from Gnus (though it can easily from, say,
Netscape Messenger).

Further, even if I manually establish a connection (by, say, running 
'ping' from an xterm), Gnus stays stuck (in my original posting, I 
had erroneously written that in this case, Gnus would continue to work
properly - but this was either pure luck, or a misobservation).

Could it be that Gnus, when it starts, stores some information about
the server, which it assumes to be constant during the whole session?
And if my router disconnects, and reconnects later, some parameters
changed (for example, the IP address assigned to me is likely to be
different on every dial in, because I don't have an ISP who would
provide me with a fixed IP address). Any other
things I could ty to track down that nasty problem?

This does indeed solve the problem!!!!

Do you see a way to automate this a bit?

For example, how could I create the server buffer automatically
when gnus starts?

        (defun (conf-gnus) "gnus with server buffer" 
                ; ???? what to put here????)

        (add-hook 'gnus-started-hook 'conf-gnus)

Then, as a maximum of comfort, I would like to have an interactive
function which switches to the server buffer, and closes and reopens
the server, and switches back. 

Buffer switching seems to be easy, but how would I tackle the
server handling?

Sorry, I should have taken more care about correct syntax here. Well,
let's rephrase:

So far, I came to the solution to put into .gnus a function

(defun mk-gnus-server-buffer () "Add *Server* buffer to gnus"
   (interactive)
   (save-excursion
	   (gnus-group-enter-server-mode))
)

The idea is that this function could create a server-buffer if
automatically. I could then put it into gnus-started-hook to have the
server buffer created.

Interestingly, the save-excursion does not work as expected.  From the
documentation, I concluded that it should save the current buffer, and
restore it in the end; but when mk-gnus-server-buffer is executed,
Gnus switches to the server buffer and stays there, and I have to
switch back manually.
