Timeouts with RAS OpenDocument: CORBA Error reported

Question

I am trying to code a .net application using the Report Application Server in a Crystal Enterprise 10 environment.  My code so far is very simple:
s = mgr.Logon("user", "pw", "server", "secEnterprise");
ReportAppFactory factory = (ReportAppFactory)s.GetService("", "RASReportFactory").Interface;
EnterpriseService esvc = s.GetService("InfoStore");
rcd = factory.OpenDocument(201, 0);
This works fine when I run it against a test server (Windows Server 2003) running in a VM on my local machine.  However, when I run this against my production server (also Windows Server 2003) it fails.  The exception I get on the client side says that the request has timed out because the server has not responded in 600000ms.  On the server side, I see the following error in the RAS server's log:
ErrorLog 2010  3  4 20:39:51.156 8464 9368 (Y:\servers\ras\crystalras\dts\corbaclientrequestcommadapter.cpp:340): EXCEPTION: IDL:omg.org/CORBA/COMM_FAILURE:1.0: Corba client dropped connection prematurely. reqType=154 agentId=""
I've tried shutting off the firewalls on both the client and the server, to no avail. I've also tried using the -port <ipaddress>:<port> switch in the CMS command line and the -ns <cmsip>:<cmsport> switch in the RAS command line, also to no avail.  My only other obvious move at this point is to sacrifice a fatted calf to the CORBA gods, but before I make that much of a mess I should probably see if anyone has solved a similar problem. 
Any advice, anyone?  Thanks in advance,
David

So does the report take longer than 10 minutes to process?
If not, then you'd best do some network snooping (using something like Wireshark), to see what's blocking the access.
If firewall is indeed blocking, then you'd need to reference the following document here:
