When I research online come across that the error cause due to following reasons

1. Application Pools Identity account password may changed

2. The administrator has stopped the application pool

To Enable Service

1. Open up IIS Manager and

3. Select Application Pools and Start (if Services stopped)

If changed Identity account password

4. Locate your App Pool account and right-click on it and select ‘Advanced Settings’.

5. Click on the right of the Identity box to change it (A window will pop up).

6.  Click on Set and simply retype your App Pool Identity in there with the new password.

Thanks for this post. It pointed me in the correct direction.
The identity hadn't changed for me but I noticed that because I'd changed the password against the linked identity the sharepoint application pool had stopped. I went into the Advanced Settings and re-entered the password and all was well.

Man! You are a hero! I lost 5 hours solving all kinds of network related problems as suggested on MSD due to haveng "A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 - The specified network name is no longer available.)" in event log.

But the problem was: during the installation of Project Server 2010 installer shutting down application pools.

Thank you very much your you post.

Thanks Man, that really helped me. I changed the service account password for the app pool and resetting the password worked from IIS.

Hi Faizal,

Please let me know more information, Server Error is very generic, is it happen once installation is completed, or during installation? Or config. Time.

Sharepoint 2007 is working after "Configures SharePoint Products and Technologies." but when we tried to open site it gives scripts error.

Please provide your email address so i will send all snapshots.

Great Post. Thank you very much Faizal. I was very much disappointed after working very hard on CRM, suddenly i start receiving "Service Unavailable error.", but you saved my life.

Other than Application Pool in Stopped status, There are few more reasons for Service Unavailable: HTTP Error 503. The service is unavailable in SharePoint, like Password expiry, etc.

Found this checklist to resolve this error in SharePointDiary.com -
