we had a phenomen similiar to this (although i'm not sure, whether this is the same cause)
when accessing an server, all computer got an answer execpt for one. the reason behind this was the following: the server we accessed was a bigIP which divided the workload on different apache webservers behind. once you connect to the bigIP it saves your IP or hostname, and would ALLWAYS redirect you to the same webserver behind. (this is done to ensure your open session is allways on the same computer) the bigIP would realize, when the apache webserver is down, but NOT if the tomcat behind the apache webserver is down. however, without the tomcat working for the apache you would never get an answer. (in our case the one computer not working was directed on the apache without tomcat) IF you've something similiar to what we had here, there's no chance you can solve it on client side. that would have to be done on server side. (except you could try to get a different hostname/IP) well, just an idea... ~Heiko -----Ursprungliche Nachricht----- Von: Jens Rantil [mailto:[EMAIL PROTECTED]] Gesendet: Samstag, 14.
