I am having this same problem... but deferently....
I use AMD 2600 XP with A7V8X mobo with 512 MB DDR400 & 80GB UATA....
The problem is with winXP SP2 installetion.... i cant connect to more than 2 network connection at the same time... what happens is i have two network card to share my 32Kbps locan calbe connection betwen my 2 pc... some time i connect the RIL CDMA to share that....
when ever in WINXP i try to connect more than 2 network connection the system just reboots without worning..... & if i disable the LAN (The single one..).... i cant enable it while OS is running.... as when connecting the system just reboots.... i have to detach the CAT5 cable then enable it & then restart... this way the single LAN connects... but there is no way i can connect 2 network connection......
this happens only in winXP... as i have checked with win2k SP4, win2K sever SP1 & with good old win98 se they r all works fine....
i work very hard to slove the problem... i tryed lots of things... after a month i came up with this answer...
I had winXP Pro corporate edition.... later i odtain the SP2 cd & then i slipstreemed it in a CD to install the SP2 directly....
i noticed that when in install the OS (winXP) from that slipstreem CD the problem happens... but if i install the OS from the old cd then install SP2 after the OS is installed... there is no problem....
now u will think this is dew to a corropt Slipstreem.... but i have tryed that slipstreem many times... i have burnt it (as a bootable CD) many time in my CDRW to b sure i dont miss any thing.... i have installed the XP with SP2 10+ times... i didnt find any errors while installing....
I follwed
this guide for slipstreeming.....
