I have several Compaq Deskpro 2000 computers that we have recently upgraded to Windows ME and installed 3Com 3C905B-TXNM network adapters. The BIOS is up to date and all drivers are the most recent that I could locate. However, if a network cable is connected, the computer hangs. This happens if WinME is already running, or on startup if the cable is connected at boot time. It is a hard lockup requiring powering the computer off/on. I have seen information telling me to turn off media detection, but this does not solve the problem; in fact it causes new problems. Any help will be appreciated.
