FQDN issue after Website deployment

Hi,

  I have a website which is load balanced. I use a Fully qualified domain name on the Vip of the Load balancer. I am using IIS 7 , .NET 4.0 , Windows 2008 Server.

Issue : 

  When i deploy the website, i stop the IIS, do the deployment , start the IIS. 

Post deployment the VIP goes down or the FQDN does not work.   This happens after every deployment.

Please suggest how to overcome this issue.
