Are distributed transactions bad?

The stored procedure on ServerC executes a distributed query against ServerD, and then all four computers are involved in the distributed transaction.
Can a remote server enlist in a distributed transaction?

The only way for a remote server to enlist in the transaction is to be the target of a distributed query or a remote stored procedure call.
