New-SPWebApplication doesn't deploy to WFE's sharepoint 2013

I have a sharepoint 2013 farm setup and for the most part working the way it should.  However, I have to spend exteme amounts of time and patience every time I add a new web application, extend an existing one, delete a web application, or have to deploy development code that requires communication to all the IIS configurations on each WFE.  Sometime it takes upto 12 hours or longer to finish and 75% of the time it doesn't propagate to the two WFE's at all.  In those cases I have to run the sharepoint configuration wizard and remove them from the farm and then readd them in order to be sure that all the IIS site information is setup on the WFEs.  I've tried using the Central Admin webpage and the powershell scripts with the same outcome.  My setup is very simple and powerful.  I have a layer 7 loadbalancer.org appliance shaping traffic between two WFEs.  These two are vmware virtual WFE's running 4 cores each with 24GB of RAM and 10Gbps network, and another virtual server running apps such as search and CA with the same hardware config.  All of these running windows server 2012 and Sharepoint 2013.  My SQL server is a physical server with 2 processors and 65GB of RAM running sql server 2008 R2 and windows server 2008 R2 with 8Gbps Network. All are in the same subnet on the same switch.  I've followed many guides to fix any loopback problems and added setting in the hosts file to point each host to their local IP address.  I've also disabled all IPv6 on each network cards.   Everything is working quickly except for administrative functions in the Central Admin Web Application Management section.  Anytime I run the "New" or "extend" buttons it will start to display the pop-up configuration window and hang for a while.  Sometime it will show up and sometimes I will have to close and click the button again.  After I get a successful pop-up window I enter the configuration for the new site and click"OK" and then nothing.  I can click OK again and again and it doesn't look like anything is happening.  After some time it will sometime say successful but most of the time gives a "Page cannot be displayed message" if it changes at all.  If I cancel or close the window and wait I will sometimes get a successful creation sometimes nothing at all.  Any ideas would be greatly appreciated.  The only error I got the last time I tried to create a new webapp was...
