recently I had to move all my applications from a server machine (which is going to be dismissed) to another one. Both machines run Windows Server 2008 R2 and IIS 7.5.

I exported the configuration of the SourceServer to the DestinationServer and I re-assigned the IP to point to the new server.

When I ping the site URL it gives me a positive response but when I try to access any website it gives back a 503 error (Service Unaivailable). I cannot find the solution to this problem, maybe there is something wrong with the configuration that I imported but I don't know what.

May sombody help please? Thanks

Usually this is due to an issue with the app pool configuration, but check the System event log for events in the relevant time frame and you should get a good clue as to the cause. Things to look for would be conflicts between applications sharing app pools or missing dependencies on the new server. – Somantra Sep 23 '11 at 13:20
Is DestinationServer a fresh install? What was your exact step-by-step process for export/import? What type of web application is it? – Daniel Lucas Sep 23 '11 at 18:16
Please supply as much additional information as possible, like: website logfiles (IIS W3SVC logs), configuration samples, detailed error descriptions and possibly events from the system Application Log, if any relevant. – Mathias R. Jessen Dec 26 '11 at 2:26
