AspCompat = "true" leads to the COM Exception

[Neeraj]

I am using AspCompat="true" in the page directive from
where I am calling Interop written in vb 6.0 which is
deployed on COM+ Server.

On some pages I am getting the error :

Exception Type: System.Web.HttpUnhandledException
Info: System.Web.HttpUnhandledException: Exception of type
System.Web.HttpUnhandledException was thrown. --->
SCTMatrixExceptionMng.MatrixException: COM object with
CLSID {77D5DECC-6668-419C-AEA0-27A478DDBE61} is either not
valid or not registered. --->
System.Runtime.InteropServices.COMException (0x80040154):
COM object with CLSID {77D5DECC-6668-419C-AEA0-
27A478DDBE61} is either not valid or not registered.

To add to this, the same is working fine on the local pc,
but giving error when deployed on the server.
What could be the possible reason? Is there any setting
for the same on the COM+ Server, or at some other place?

Can somebody suggest me solution for this...
