Yutaka, Thanks for the information, I have researched the references you supplied and with some experimentation I have found a solution. If the local LAN (192,168,0,8) card is initialised first and the ISP broadband LAN second (order given by ipconfig) the system works correctly. If the initialisation occurs the other way around I get the symptoms I first described. Although I have not extensivly exprimented it appears that WIN XP is initialising the LAN cards in MAC address order and therfore you get a 50/50 chance of getting it right first time. If I get time I will examine this futher but for now I have a working system and I am grateful for that. thanks again Stuart ----- Original Message ----- From: "Yutaka Sato" <pficabdyi-jk6bmqu4eqnw.ml@delegate.org> To: <pficabdyi-jk6bmqu4eqnw.ml@delegate.org> Cc: <paegabdyi-jk6bmqu4eqnw.ml@delegate.org> Sent: Saturday, November 19, 2005 12:54 AM Subject: Re: [DeleGate-En:3079] DNS Server on WINXP] > In message <_A3075@delegate-en.ML_> on 11/17/05(06:55:31) > you "SMF" <paegabdyi-jk6bmqu4eqnw.ml@delegate.org> wrote: > | > I think a detailed log of DeleGate for debugging the resolver will be > | > helpful.
