ADMT and SBS 2003

I read a post regarding the ADMT tool and SBS 2003. I have inherited a project that may require the use of the ADMT tool: I have a network with 2 Windows 2000 servers running 2 different domains. The companies have since merged and they have invested in SBS 2003 with a new box to house it.

I read a posted that suggested a use a customized runas command to work around the no domain trusts allowed for SBS 2003. I have been searching the web for more info, but I can’t find anything more.

Any help for where to find the documentation or resources will be greatly appreciated.
