Do not have more info about what's there on network, the only new thing I can add is that the client is dead not reacting even on keyborad or anything else. Trond, would you have and idea what to try now or what other information to find to get any further in this? The clients are different machines - Intel x AMD with different boards, NICs etc. The server is dead too, but it may recover after some time - I can not afford leaving it for longer time to see what happens.
