2Gb ceiling on NT4.0

I’m trying to create a BDC to backup our server. The machine I’m trying this on has a 120Gb hard drive. I managed to get it done, but the NT4.0 installation limited me to 2Gb for the C Drive.

Is there a way around this? My original server that I’m trying to protect has a 4Gb partition for C: I was gonna just image it to the new drive – but this would make it a copy of the PDC, and from what I can tell – there is no way to turn this into a BDC. It has to be done during installation.

Any ideas would be appreciated.
Thanks
Sid
