Hello everybody,

I have a very weird problem with a laptop Toshiba Sat Pro 6100 with an Intel Pro/100 VE network card.
I recently repartitioned my HDD and installed a Windows (XP Pro) and a Linux (Slackware 10) on different partitions.
The problem is that I can not connect to any Workgroup or Domain, neither in Windows nor in Linux. I have absoluttely no idea what could this be; I just suspect it's something about the network card's BIOS, but I don't seem to find any tools for testing this.
Prior to reinstalling my OSs I had absolutely no problem; actually, connecting to two different domains worked even after setting up the fresh Windows, but after a booting back and forth it just stopped.

I tried changing the computer's name, going from workgroup to domain but it can't find the domain controller.

Can anybody help?
Thank you in advance,
Adrian
