Hi Avinash,
It looks to me like you are wildly trying everything apart from reading the documentation in order to get this to work.... ;-)
II think you are creating a DOS automation partition, and this TCP error means you have not updated BootDisk creator with the correct DOS drivers for your NIC.
Next, UNDI is only available from the PXE stack, which is to say you have to PXE boot your machine in order to utilise this driver. You cannot use the UNDI driver from any other boot mechanism. This is not an Altiris limitation -this is just the way PXE works.
For various reasons (including troublesome machines), I have a VMWare install of Deployment Server with a bridged NIC. This allow me to test all this kind of stuff at my desk without having to bother initially with the various network pains. Once I'm happy that my Uber-simple config works, I can push the fruits of my labour up to one of our main servers.
Kind Regards,
Ian./
