2 GB Partition

My NT Server came preloaded with WINNT directory on a 2GB partition (C: drive). This has limited us in spite of the fact that we have a load more disk space. It seems like everybody’s software wants to be loaded in the main partition in order to operate properly… IE: Symantec AV & Veritas BU Exec. Can I safely increase the size of my system partition without reload of NT?
