Hiya John,
First off could you please specify which version of volatility you're
using (whether you're using a tarball, or the sources from subversion)?
Also, whilst I can't comment too well on the 1.3 branch, I don't think
Windows 2003 is supported, I believe it's mostly aimed at XP SP2.
Having said that, it is possible to manually specify a DTB in the 1.4
branch using --dtb and in the 1.3 branch using -b (although for 1.3 this
is probably plugin dependent).
I'll leave it to someone who's been working with Volatility longer to
give you a more in-depth answer once you let us know which version you
were using, but hopefully this'll let you work around the problem for a
bit... 5:)
