ML350 partition size w/ W2K Server

[tw eby]

I have a new ML350 g4 with smart array 642 with 5 147gig drives in a RAID 5

I installed SBS server 2000 using the smart start disks

After installation the properties of C: show a disk size of 4gig & I keep getting out of disk space messages while trying to install software. If I go into the disk manager it shows a partition size of 546gig for drive C

anyone know what went wrong for me and what I need to do so I can use all of the partition?

Thanks
Tom
