  Hi all,

  I have a project where I have the following hardware:

  2 x HyperV servers running Server 2008 Enterprise R2

  Each HyperV server has 3 Virtual Machines also running Server 2008 Enterprise R2

  The 6 virtual machines are slit as follows:

  vm1 - lives on hyperv01 - runs sql server 2008 enterprise R2

  vm2 - lives on hyperv01 - runs Dynamics CRM 2011 rollup 5

  vm3 - lives on hyperv01 - disabled for now but will run Kentico CMS later

   

  vm4 - lives on hyperv02 - runs sql server 2008 enterprise R2

  vm5 - lives on hyperv02 - runs Dynamics CRM 2011 rollup 5

  vm6 - lives on hyperv02 - disabled for now but will run Kentico CMS later

  OK, now to my issue:

  I have CRM installed and it appears to be responsive enough whilst I only have the 1st crm server deployed but when I install the second crm server and choose to join an existing org i.e. I point to the sql server on vm1, things start to slow down.

  I have NLB installed and again, this could be contributing to the slow down so I disabled one of the crm servers in NLB and again things seem fast.

  My overriding issue is that I believe that when I join the 2nd crm server to the org, it must overwrite some database files because it appears to break the crm home page on the first crm server.  Below is a screenshot of the error I am seeing.

   

  If I reinstall the first CRM server then it overwrites the files again and the 2nd server displays the above behaviour.

  I have struggles all this week and have a case open with Microsoft.  I am awaiting a call back but I believe it will be monday now before I can speak to them.

  Things I have done and have been caught out with throughout the process of getting this up and running:

  1. Ensured that I have ticked "The deployment uses an NLB" in Dynamics CRM deployment manager.

  2. Follwed http://technet.microsoft.com/en-us/library/hh699791.aspx to the letter.

  DB mirroring and failover works fine and I am happy with that, it is purely the fact that I feel I am not adding the 2nd server correctly.

  Please can anyone advise what I could be doing wrong?
