I have MTS on my NT4 Workstation and also on a NT4 Server with all the service packs. Im trying to test a simple 3 Tier architecture with COM/DCOM/MTS.<br>The presentation layer calls a business object within MTS which calls a Data object which returns a recordset back to the business object and then raises an event on the client with some detail from the recordset. Simple enough.<br><br>The following is working<br><br>I can call the local DCOM server direct on my workstation.<br>I can call the local MTS business object through the local MTS on my workstation.<br>I can call the NT Server DCOM server direct on my workstation.<br>However I cannot call the NT Server MTS business object through the MTS on the NT Server<br>All I get is 'permission denied'.<br><br>Therefore I have proved that<br>The business object works OK<br>The DCOM Server works OK (on both local and server machines)<br>MTS on my local machine works OK<br><br>So the specific problem is that I cannot access an MTS object on a remote server but I have no problem locally.<br><br>Any ideas?<br>
