I have MS Office 2003 and have recently had problems when starting my server and PC in that Outlook shows 'Disconnected' so I can't access email. Web access to the outlook email account is also blocked but other internet access is fine. Restarting helped at first. When the problem continued on switch on the next day I changed the switch sitting between my server and PC and thought that had cured the problem but this morning the same has happened again. My LAN/WAN show working fine and error messages from BT Broadband say 'can't locate network card.
