have been running 0704 with very few problems for the past few weeks...all of a sudden a very strange thing is happening. the dcerouter seems to have cut itself off from the rest of the network...i can still access the internet on the kde desktop, but it will not find any other computer on the network, and no other computer on the network can see it. orbitors can't connect, no admin website, no shares and no ping. nothing on my network has change, nothing added etc. everything is exactly the same as it was. I checked all firewalls, cables, and all the thing you are supposed to check and everything seems fine. does anyone have any ideas?
