Hi guys, (and girls) :)

Im currently building a Lync Server 2010 test lab for a client & Im having some issues with getting the Lync Control Panel to open properly.  I get the ‘Navigation to the webpage was canceled’ error.  
I am able to load the control panel via and via the IIS page.

1 x DC - Server 2008 R2
1 x Front End Server (collocated A/V & Mediation) - Server 2008 R2
1 x SQL 2008 SP1 server
1 x Exchange Server - Exchange 2007 SP3
2 x Lync Client Machines - Windows 7 Enterprise x86
FE Pool:

I have done some investigation & some of the information seems to point towards not having a DNS entry for the Lync pool name (lyncpool in this instance), other information points towards there being some issues with certificates.  I have also added the simple URL to the topology & re-published it, and also added the DNS entry for admin to point to the front end server (LyncSRV1 in this instance), which is  I made sure I also added the SRV record for _sipinternaltls_tcp Port 5061 & the host service is

All DNS entries, such as dialin & meet have been added to point to the same IP address as above.

These are the steps I've attempted without success:
1. Re-run the bootstrapper (Step 2 of the Deplyment Wizrad for those not familiar with this term)
 after adding the 'admin' Simple URL & republishing the topology
2. Checked the IIS website settings are set to "Use all unassigned IP's"

Below is a copy of the rewrite rule within the web.config file from IIS:
<rule name="CSCP Combined Rule" stopProcessing="true">
  <match url="(.*)" />
  <conditions logicalGrouping="MatchAny">
   <add input="{HTTP_HOST}/{R:0}" pattern="^$" />
  <action type="Redirect" url="" redirectType="Found" />

There doesnt appear to be anything missing in the config file.

Any help or suggestions would be greatly appreciated.  
Im sure there is something missing but I can’t for the life of me figure out what it is…no doubt something simple.
