Thanks for your response guys.

I am surprised to see how difficult it is to change some registry data with NT PCs. Windows 95/98 are a charm in this view...

About your mail Les: we are gonna use winnt.sif and the CD installation of windows XP professional to perform our work(about 65 PC to install).

Here's why i had to take that choice:
1- The company where i gonna make the installation uses different types of PCs from PII to PIV. There are too much hardware differences to permit me to use the sysprerp tool.
2- We will have to make all the installations in a weekend. So we will need to start many installations at the same time. That's why i want to use the cd, cause the network will be too in demand and it will slow our work.
Another reason why i don't use the network for windows XP installation is that we are gonna install all software from the network from adobe acrobat 5 to Office XP. So while some PCs will have Windows XP installed locally others will use the network to get Office XP, Adobe, faxport and etc.. installed from the network.

The main problem with cd-rom installation and winnt.sif is that i cannot create a user template where i could say exactly what parameters i want for each users. This is where you can see the reason of this note...

I thought it would be possible to change IP data, PC name, PC info and some regional settings for every user. So i made a kix script with the kixpop tool from Shawn that shows an html page with some choices of automated installation:
Here an example:
1- Configure network configuration
2- Install Office XP
3- Install Adobe 5, faxport
etc...

You simply type the number of your choice and the installation starts.
For the option 1, the technician is sent to another html page that ask him the name of the user. The technician writes the name and kix gets this line and look for it in a .ini file. He gets the information from this file and installs it on the PC. So i thought that i could simply make some registry change to force the OS to change the pcname, IP address etc...

Well seems i did not took the good road on that one!

Any suggestions from you guys would be appreciated.
As you see, i'm used to 95/98 OS. I'm still new to NT ones.
