I don't see which Linux distribution you're using; you should specify that because it's essential - in some distributions this problem might have different "easy" solutions than in others. For example installing an rpm package to fix it works only for those distributions that the rpm is aimed at - and not at all in Debian, for example.
If there is NTFS support (either read-only, like 'ntfs', or read-write, like ntfs-3g or something) built into the kernel, then you don't need to specify the filesystem with -t; a simple
mkdir -p /mnt/win2
mount /dev/hda1 /mnt/win2
ought to work. The mkdir command ensures that the directory exists; make sure that hda1 is the partition you want to mount - some (newer) distributions nowadays call the first partition of the primary harddisk sda1 and not hda1 even if it was IDE-connected disk.
If it doesn't work, tell what error it gives. No error message means the command did work; if it didn't, then you should get error(s) that might help in solving the problem.
