Cognos 10.2.2 distributed cluster, remote dispatcher will not become "Available"

[r_aldrich]

I have been a long time reader of this forum and have learned a great deal from others experiences.    Today, I have a situation for which I have not yet found a resolution to.     Perhaps I am trying something that really is not possible.   So if anyone can lend a thought or two, it would be appreciated.

I am attempting a mixed distributed install of Cognos 10.2.2 using AIX 7.1 and Windows 2008 R2.   The purpose of this configuration is to utilize some Legacy (old) 32bit Clients connections and data sources which only exist in our Windows Platform.   We have published a number of Framework packages where Dynamic Query Mode is not enabled.    Our thought was to create this mixed environment so we could continue to run those packages until they could be regression tested using Dynamic Query mode.    Our AIX platform does not have any 32 bit clients installed on it.
                                                                       
Is there any reason why this configuration will not work?               
                                                                       
The AIX install is a single server running 4 dispatchers successfully,  each in a separate WebSphere profile                                   
1) Content Manager
2) Gateway running IBM Servlet Gateway                                 
3) a 32 bit Report Dispatcher.  ( using this for power play cubes )
4) a 64 bit Report Dispatcher.  ( using this for 64 bit jdbc connections )                                       
                                                                       
The Windows 2008 R2 install is a single server JVM running 1 report dispatcher with its dedicated WebSphere profile as well                                 
1) a 32 bit Report Dispatcher.  ( with 32 bit native Oracle and SQL Server clients )                                         
                                                                       
The AIX Server is running IBM WebSphere 8.5.5.2  and using IBM SDK 6.0 
The Win Server is running IBM WebSphere 8.5.5.4 and uses IBM SDK 6.0 as well  ( purposely kept the JAVA versions the same.                                                                     
                                                                       
The Windows dispatcher successfully registers in the Cognos Cluster, but it's status remains unavailable.                                   
                                                                       
The only error message I am seeing is from both the AIX report dispatchers
192.xxx.xx.xxx:9084 2426204 2015-02-09 14:10:06.504-5actionQueuena  na0Thread-73 DISP 61001 Audit.Other.dispatcher.DISP.pogopogocom.   
cognos.p2plb.model.NodeHospitalFailure <messages><message><messageString>DPR-DPR-1035 Dispatcher detected an  error.</messageString></message></messages>Ping of sick dispatcher   
192.xxx.xx.xxx:9086/p2pd/servlet/dispatch failed.  Error code = 
Failed to send HTTP request or read HTTP response                       

AIX report dispatchers run on ports 9084 & 9085, Windows has port 9086 and firewall is open on all 10 ports in this sequence 908x enabling dispatchers to communicate.

I would expect other log entries, but am not seeing any , I have increased dispatcher logging to "trace" but no additional info is written to logs.  (perhaps a restart is needed)

When I enter http://192.xxx.xx.xxx:9086/p2pd/servlet/dispatch in to the windows 2008 browser, I do see the Cognos Public folders.
But only when I am on the server, this URL fails from my desktop as well as from the AIX server... So I am leaning towards a port issue.
