Delete trigger & COM+

Hi, I'm building a website that interacts with MS SQLserver(v7) via a Buisiness Rule-layer developed in COM+ with VB(v6 sp5). The website is an add-on on a existing client/server app. Now I have delete triggers on almost every table and they work perfectly in the c/s app and when runned in the query analyzer. But when I try to do the same with COM+ I get the the next error message on line 10:
"Cannot use SAVE TRANSACTION within a distributed transaction."

Here follows the code. Hopefully anybody can help me with this problem.

SQL-statement:

Function getDeleteRequestSQL(ByRef strRequestId As String) As String
Dim strSQL As String
strSQL = "DELETE FROM thmld2 WHERE right(hdmcode,8)='" & strRequestId & "'"
getDeleteRequestSQL = strSQL
End Function

And then the place where the error occurs.

GetConnection cnConn
strSQL = getDeleteRequestSQL(reqId)
10 cnConn.Execute strSQL, , adExecuteNoRecords

And finaly the trigger:

create trigger td_thmld2 on thmld2 for delete as
begin
declare
@.numrows int,
@.errno int,
@.errmsg varchar(255)

select @.numrows = @.@.rowcount
if @.numrows = 0
return

select @.numrows = (select count(*) from trigstat with (nolock) )
if @.numrows > 0
return

save transaction trans_td_thmld2 <-- REASON FOR ERROR?

/* delete all children in "thmstat" */
delete thmstat
from thmstat t2, deleted t1
where t2.hdmcode = t1.hdmcode

/* delete all children in "thmldlk1" */
delete thmldlk1
from thmldlk1 t2, deleted t1
where t2.hdmlmldcode = t1.hdmcode

/* errors handling */
error:
raiserror @.errno @.errmsg
rollback transaction trans_td_thmld2
endDon't know what that is, but it has nothing to do with the trigger...

Well that me guessing again...

Sounds more like you're establishing a tran across many servers...|||The components I've created are all located within one dll. The dll is active in the component services on my own webserver and is working fine. So the action isn't distributed over the network. :(
