Depends if you have basic or dynamic disks. The max limit of a basic disk in windows in general is 2TB, but needs to be smaller than that otherwise it will see some blank space on the end. Dynamic disks have a larger capacity.

Depends on the volume type, using the classic "MBR" type used by default, any single LUN cannot be larger than 2TB. You can use dynamic volumes concatenate or stripe multiple LUNs together into a larger volume though.

Starting with SP1 of Windows Server 2003, you can now use a "GPT" disk type and not have the 2TB limit. I use this on several of our file servers with ~4TB LUNs. Just go into disk management and right click on the Disk # and select "Convert to GPT" before you put any partitions on it. There is no way to convert a MBR to GPT once you have data on it.
