Here's the situation.
*PC running Win7 Pro, non-domain joined.
*Server running server 2012 hosting a DCOM application. Domain member.
The non-domain pc cannot seem to launch the dcom application no matter what I try. I can map drives to the server just fine by supplying credentials via net use commands. DCOM doesn't seem to operate on that level. I have control over the 2012 server and can make whatever changes are necessary however the PC is not allowed to join the domain.
Does anyone know a workaround? On the server, the event logs show DCOM permission denied errors coming from a NULL SID. I'm not sure how I can cause the workstation to produce a valid sid to the server without joining it to the domain.
