I'm having some troubles with ASE 12.5 and MS DTC managed transactions.

I'm using ASE 12.5
Sybase ASE ODBC driver
The Distributed Transaction Model is Native OLE

When I'm trying to connect to Sybase server that is in a different domain, appears de following message:

[MERANT][ODBC Sybase drive] Distributed transaction enlistmen failed

to connect to this domain I use a router and I don't know what is happening

If somebody can help me,
