SQL Across Domain Boundary

I have a .Net Windows client app that needs to access a SQL server database
across a domain boundary. The app uses windows security. The user logs into
the app with windows domain credentials while the app uses impersonation.
Creating a SQL server account (using SQL security rather than windows
security) is not an option.

The app works fine when run from within a trusted NT domain. It fails when
run from an untrusted domain.

Is there a way, without creating a new SQL account, to pass windows
credentials through untrusted boundaries from a WinForm app? Bear in mind
that the user logging into the app already has windows domain based
privileges established on the SQL server.

Thanks,
Geo
