Problema con MSDTC (SQL)

Hola

Tenemos el siguiente problema:
Ambiente:
Servidor A con ISA Server y SQL Server 2000
Servidor B SQL Server 2000

En el servidor A tenemos configurada la tabla WebProxyLog con un trigger el
cual por cada insert del isa server en la misma inserta algunos campos en
otra tabla del Servidor B

El Servidor B esta linkeado en las "Link Server" del Servidor A.

Los MSDTC estan levantados en los 2 servidores pero al ejecutarce el trigger
da el siguiente error:

Server: Msg 7391, Level 16, State 1, Procedure Trg_Insert, Line 7
The operation could not be performed because the OLE DB provider 'SQLOLEDB'
was unable to begin a distributed transaction.
[OLE/DB provider returned message: New transaction cannot enlist in the
specified transaction coordinator. ]
OLE DB error trace [OLE/DB Provider 'SQLOLEDB'
ITransactionJoin::JoinTransaction returned 0x8004d00a].

Probamos correr el insert que esta dentro del trigger (sobre el query
analyzer) y funciono bien.
Probamos en el trigger poner el comando "SET XACT_ABORT ON" y su respectivo
"OFF" sin resultados
Probamos con otro server (Servidor C) que no tiene instalado el ISA Server y
funciona bien.

Alguien sabe si el ISA Server Bloquea algo?
Si hay que abrir algun puerto? Cual es el puerto?
Si podriamos haber omitido algo en el server A? (dado que del C al B
funciona ok)
Alguna otra idea?

Ante todo muchas gracias!!!
