App-V 5 Publishing Server + Load Balancing (NetScaler) issue

Question

All, 
I have attempted to load balance my App-V 5.0 deployment, which includes two nodes (appv-1 and appv-2) on a Citrix NetScaler VPX appliance. 
The management server is working fine, when browsing to the load balanced VIP DNS alias - pass-through authentication works great and the management console is displayed. 
When I attempt to browse to the load balanced VIP DNS alias for the Publishing Server, it prompts for authentication credentials, then displays the following error:
Method not allowed. Please see the service help page for constructing valid requests to the service.
When I attempt to browse using the same internet explorer instance to http://appv-1.fqdn:8088 it displays the XML page after entering authentication credentials. 
Here is my set-up & what I have done.... 
Appv-1 Server
Management Server installed on Port:8088
Publishing Server installed on Port:8090
SQL Cluster and Mirroring configured (tested and working)
Appv-2 Server
Management Server installed on Port:8088
Publishing Server installed on Port:8090
SQL Cluster and Mirroring configured (tested and working)
NetScaler 
Management VIP: 10.1.1.148
Publishing VIP: 10.1.1.124 
Both Appv-1 and Appv-2 are setup as services and bound to the corresponding Virtual Servers.
Load balance alogrith - persistence - source IP: 255.255.255.255 - Least Connection
DNS and AD Modifications
host A record - appvmgmtsrv.fqdn = 10.1.1.148
host A record - appvpubsrv.fqdn = 10.1.1.124
computer object create in same domain for appvmgmtsrv and appvpubsrv
SPN Modifications: 
setspn –A http/appvmgmtsrv:8088 domain\appvmgmtsrv
setspn –A http/appvpubsrv:8089 domain\appvpubsrv
setspn –A http/appvmgmtsrv.domain.local:8088 domain\appvmgmtsrv
setspn –A http/appvpubsrv.domain.local:8090 domain\appvpubsrv
IIS Modifications:
Appv-1 and Appv-2 - ApplicationHost.config - modified with below line for both Management and Publishing Server sections:
<windowsAuthentication enabled="true" useKernelMode="true" useAppPoolCredentials="true" />
Rebooted and IIS starts correctly.
Testing 
On Appv-1 if I browse to http://appvmgmtsrv.fqdn:8088/console.html it asks for authentication, when authentication is entered it fails. 
On another other machine in the environment if I browse to http://appvmgmtsrv.fqdn:8088/console.html it automatically loads the console with the credentials of the logged on user. 
Launching the Management Console via Load Balanced DNS name works on every other server except itself.... assume this is Kerberos modifications? (This only happens when I disable the appv-2 node on the load balancer, forcing all IIS connections to Appv-1). 
The management server issue above is not a big one and can work around that easily. The major issue is with the Publishing Server. .. . 
On Appv-2 if I browse to http://appvpubsrv.fqdn:8090 it will prompt for authentication, once enter it displays: Method not allowed. Please see the service help page for constructing valid requests to the service.
in a new tab if I enter http://appv-1.fqdn:8090 it will prompt for authentication, once enter its displays the XML page with App-V meta-data. 
Can anyone shed some light on this issue please.... When I update the App-V client with the load balanced publishing server VIP DNS it displays the following error in the event log: 
Getting server publishing data failed.
URL: http://appvpubsrv.fqdn:8090
Error code: 0x45500D27 - 0x80190195
Any help will be greatly appreciated. ....
