I have a windows 2000 server based network with several XP and windows 2000 clients. I have one particular XP client running on Dell inspiron 5100 hardware that keeps on loosing network connection to mapped server drive. Any ideas what I should be checking. This is the only machine that is having this problem. I have other Dell inspiron 5100 notebooks running Windows XP mapping to the same network drive without any problems. Thanks for your help.
