I am having a problem with my Server 2003 64 bit server. I am running out of harddrive space on my E: drive. It seems that System Volume information is trying to take up all of the space and is growing. I've tried running cleanmgr and going to more but system volume information is greyed out. I've tried to stop the volume shadow copy service and delete some of the older files but it wouldn't let me. I believe this is something Symantec is leaving behind.
