Network Symptoms

I am using Novell and it keeps saying 'error reading device NETWORK'.

First Step : Check the cables between the PC and the server, and the terminations.
More information : The most common cause of this problem is a physical fault. Check that all the cables are in their place correctly, and that none of them are broken. This may involve checking other workstations, trying another connection, or moving the terminator closer so that the exact location of any cable break can be found. If the terminators are ungrounded, grounding them may improve the cabling.
