Hi all, sorry for the lenght of this but I am trying to give you as much info as possible : my win / exchange log reports : the DNS proxy agent will not bind to the ip address 192.168.0.1 the error may indicate a problem with tcp/ip networking .............. I have no firewall or routers attached ( now ) I have checked the netsettings to be correct I can ping it ok but it just refuses to play ball, anyone point me in the right direction steve alcock
