I installed and tested the sme server 5.5 two days ago and everything is fine.
made all client pcs (Win ME) accept dynamic ip addresses and everything is fine.
clients can reach internet, server-manager and so forth.
but periodically, none of the clients can access the gateway and thus the internet.
when i go back to the server pc the monitor is blank and the the server does not appear to respond to the keyboard therefor i can't access the console
and because the connection between client and server is cut i can't access the server-manager either.
the client pcs (20 of them) are still networked and fully functional
the only thing left is to reboot the server which then acts as if nothing happened (except for the hard drive check).
when rebooted it works perfectly, well, until it happens again.
