or the encryption it uses machine specific keys in the iisConfiguration and iisWasKey containers. When the applicationHost.config is moved to a different server IIS can no longer decrypt the settings.

To get this working you can export and import the keys from the original server.

Export using the following commands

IIS使用了加密密钥，当applicationHost.config移到不同的服务器时，由于密钥不同，IIS就没办法再解密了，解决的办法是从原始服务器上备份密钥，再在这台服务器上还原，备份方法：

aspnet_regiis（这个程序一般在.NET的安装目录下，自己用DIR命令查看一下)

aspnet_regiis -px "iisConfigurationKey" "D:\iisConfigurationKey.xml" -pri
aspnet_regiis -px "iisWasKey" "D:\iisWasKey.xml" -pri

接着把两个文件拷到B服务器上，再导入，导入的命令参数为：

aspnet_regiis -pi "iisConfigurationKey" "D:\iisConfigurationKey.xml"
aspnet_regiis -pi "iisWasKey" "D:\iisWasKey.xml"

一般就可以合用了！
