Oh my...  I haven't tested any of these on 64-bit Win2003 or SQL 2005.  They were only tested on SQL 2000, 32-bit.  XP's on SQL 2005 have been deprecated but are still allowed... for now.  A better bet might be to convert the routines to .NET assemblies for SQL 2K5.  The downloads contain the C++ source code for these routines.  If you were using SQL 2000, I'd recommend using the routines here:  http://www.sqlservercentral.com/columnists/mcoles/sql2000dbatoolkitpart3.asp, with more optimizations and additional routines added.
