MachineKeys For IIS 7.0

  • Article

IIS uses MachineKeys for encryption. IIS 6.0 uses a particular key c2319c42033a5ca7f44e731bfd3fa2b5_GUID to do the encryption. If you have worked on IIS Admin start up issues the machine keys is one of the first things we check because if you do not have the proper machine key you cannot enumerate the metabase and hence the IIS Admin service will not be able to load the metabase.

On Windows 2003 the MachineKeys are located at

C:Documents and SettingsAll UsersApplication DataMicrosoftCryptoRSAMachineKeys

With Windows 2008 the user profiles are now stored in the Users folder and the MachineKeys are now under

C:UsersAll UsersApplication DataMicrosoftCryptoRSAMachineKeys

and the ones that concern IIS are

6de9cb26d2b98c01ec4e9e8b34824aa2_GUID      iisConfigurationKey

d6d986f09a1ee04e24c949879fdb506c_GUID         NetFrameworkConfigurationKey
