[Samba] 2TB Limit for Windows Shares?

[andy liebman]

I have noticed recently that Windows XP seems to stop writing into 
Linux/Samba shares once there is 2 TB of data in the share. Windows 
Explorer is happy to report that a share has 4.8 or 8 or 10 TB of space 
available, but Windows seems to cease writing into the share once there 
are 2 TB in it.

Is this a known limitation of a) Windows or b) Samba or c) both? It 
certainly isn't a limitation of the filesystem I'm using.
