From Daniel Krüger:
I attached a patch to this dissector, which includes some corrections, updates and SDO by UDP support. I will upload a sample capture of SDO by UDP to the wiki. The patch is fuzzy tested against the current SVN rev under Linux and it builds also under MSVC2005. svn path=/trunk/; revision=20937
