Could not verify the version of Microsoft Dynamics CRM - VPC 2009 Error

I download the MS CRM VPC 2009 and did the windows update. When I reboot the system the MS CRM Web Application was not getting loaded.

I confirm that all the MS SQL SERVER and MS CRM services are running. Finally I check the Event Log and found the below error:
Could not verify the version of Microsoft Dynamics CRM at http://crm/Contoso.
The remote name could not be resolved: 'crm'

To resolve this issue, simply add the entry in HOST file.
Browse "C:\WINDOWS\system32\drivers\etc\" and open the HOSTS file in notepad and add the below entry at the end of the file :
127.0.0.1 crm

Save and close the file.
Refresh you browser.... Here your MS CRM app will get loaded....
