DCOM problem within a Samba controlled domain

[James W. Beauchamp]

Michael:
I don't know squat about most of what you describe, but in the release
announcement for 2.2.2 they indicate they fixed a number of oplock issues.
Is it possible this is related to your problem? If so you might want to try
and upgrade.

HTH

>   Problem Overview:
>   DCOM client and server running on different NT4 workstations within the
same
>   SAMBA controlled domain. The client can launch the server, create an
object
>   within the server and obtain an interface to the object (using
>   CoCreateInstanceEx), but the first method call on the interface
generates an
>   HRESULT of 0x80070005 (E_ACCESSDENIED). When run under the debugger, the
>   debugger shows that the method body is not entered, so it appears to be
some
>   access problem with the actual method call.
>
>   When client and server are run on a similar setup within an NT server
>   controlled domain the method call succeeds.

>   More Details:
>   The DCOM server is running as a system service which runs within the
>   System Account context.
>   The DCOM server has no programmatically set security.
>   The DCOM server's security permissions (as set within DCOMCnfg) are:
>   Authentication Level: none
>   Impersonation Level: Identity (though same problem when set as any of
>   other levels)
>   Access Permissions: Allow Access for "Domain Users" and "Everyone"
