Problem running site in IIS 7 64-bit server

[fugtruck]

I have a Smarterstats 5 installation on Windows Server 2008 64-bit. I setup a site in IIS but I am unable to log in. If I have the application pool running in 64-bit mode, I get the following error when I try to log in:

*******************************************

Validation of viewstate MAC failed. If this application is hosted by a Web Farm or cluster, ensure that <machineKey> configuration specifies the same validationKey and validation algorithm. AutoGenerate cannot be used in a cluster.

(There is also some additiona source and stack trace information)

*******************************************

If I have the application pool running in 32-bit mode, I get the following error when I try to log in:

*******************************************

Server Error in '/' Application.

Any suggestions on what I need to do here?

Hi-

We're running the latest release of the mail app.. Windows 2008 R2 64 Bit .. SQL Server etc..etc.. Build # 6002.. Terremark Enterprise Cloud Server Template..

We ran the default install, no problems.. I've got IIS Mangler up.. here is our config setup..

We're running IIS 7 / FTP7.5 and we've got WebMail Setup as an SSL Host with 1 site binding on Port 443

For The Basic Settings, The Application is .Net Framework Version 2.0 and Integrated Pipeline Mode.. The .NET Assembly in the GAC is the most recent release from MS.. and the most recent Telerik Controls..

Name: Microsoft .NET Compact Framework 2.0 SP2, Install Date: 20100406, Vendor: Microsoft Corporation, Version: 2.0.7045

For Authentication, Anon + Windows Auth

Application Settings, Mail Service Address = 127.0.0.1

We followed all the RTFM listed in the Forums.. basically created a basic Site in IIS and all set.. same thing with the Stats app too..

If you use HostingController8, leave the port setup as 9998 or whatever it is when you setup HC, and leave the built-in daemon running behind the external Firewall/LoadBalancer so you can have HC do provisioning.. we've had no problem...

Does the App work with their built-in daemon?

One last item, try upgrading your .NET 2.0, the version you posted is known to be an issue, perhaps that will solve it, it has a few vulnerability issues known as well. We've got Version: 2.0.7045

I had the same issue (Validation of viewstate MAC failed) Friday, managed to fix it earlier today.

It seems my App pool was using the wrong Identity (application pool identity). Once i changed it to use Network service it worked.

I also had Enable 32-bit set to False and pipeline mode set to Clasic.

Hope this helps.
