How to Properly Rename an IIS 7.5 Server?

Hello,

I've got a W2K8 R2 IIS 7.5 server that I just renamed. Now IIS app pools choke whenever I try to browse the server's pages. I suspect there's IIS-specific work to be done after the Windows server name change. Any information would be greatly appreciated.

Thanks

I did also change the server's IP address, however I'm not haivng issues connecting to the new server. Its just that my app pools die the moment I browse that newly renamed and re-IP'd IIS 7.5 server. I suspect IIS / app pool secuirty issues that arose from the name change.

Note that when the app pools die, I see event id 2307 errors plastered in the app log. The errors read:
 "The worker process for application pool 'DefaultAppPool' encountered an error 'Failed to decrypt attribute 'password'.

Is there some kind of IIS command I can run to re-establish the secuity setup? Note that we're talking about IIS7.5/W2K8 R2.

Thanks

Try  this link:

As I understand it,the error seems to indicate that the keyset does not exist anymore, could you try to regenrate new encryption keys using the method outlined in the link above?

Thanks, i'll try that.

One more error keeps popping up in the system log too.


Event 5203:
A process serving application pool 'Classic .NET AppPool' reported a failure trying to read configuration during startup. The process id was '2456'.  Please check the Application Event Log for further event messages logged by the worker process on the specific error.  The data field contains the error number.

Thoughts?

sorry,

See these posts and see if it helps any.

There appears to have run into some bug either through your app or through iis set up and configuration.

Was this ever resolved?  We'd like to make a copy of Server A (a VM) and rename it as Server B (on a second VM) so we can load balance them.  They are Web Server hosting multiple sites/applications.  Windows Server 2008 R2 / IIS 7.5.  However, before we try this we want to see if we can get an idea of what we'll be up against.
Thanks!

It seems that regenerating the keys fixed it which is what the link I posted suggested as the solution, isn't it so?

How did the link referring to do the 'SharedLibraries' install work on a 7.5 IIS?   Because it doesn't work on that.   Anyone know of what will work on the 7.5 IIS?
