I'm getting this error in the log:

"3966","2008-06-17 10:18:20","Error","System","2001","ServerStartError","SourceCode.Hosting.Server.Runtime.HostServerEngine.StartHostServer","2001 Error Starting Host Server: Failed to decrypt using provider 'RsaProtectedConfigurationProvider'. Error message from the provider: The RSA key container could not be opened.

Should I use the ASPNet_regiis tool to add K2 Server service user (k2bpservice) to the ACL of the key container using the –pa parameter?:

aspnet_regiis -pa "NetFrameworkConfigurationKey" "k2bpservice"
