We are having problems with 20 LC111 Macs on our network. They have been given static IP addresses and work ok, but sometimes they cannot logon as there is an IP address conflict as notified by the server. Also, they have been set up to print to a Laserwriter 12/640 and have been operating ok. Recently, they have not been able to see the laserwriter, but they can see the other network printers that have been set up for the PC's(win95). All of these problems appeared to happen all at once with no work or changes having been made at the server. We are at a loss for an answer. Your help would be appreciated.
