I have in intermitent connection problem - every few minutes IE says that it is unable to connect, when I click Diagnose, then Next the connection is restored. This happens on just one PC - I have 3 on the network.It may be my imagination, but when I disable the 1394 adapter, it seems to be more reliableI have reinstalled the BIOS, the network driver and chipset drivers (they were all out of date anyway)Could my problem be caused by Norton firewall? Is it likely to be software of Hardware related?1 person needs an answerI do too
