Hi Ron,
From your description you encountered the following error
======================
Error Message:Unable to validate data.
Stack Trace: at System.Web.Configuration.MachineKey.GetDecodedData(Byte[]
buf, Byte[] modifier, Int32 start, Int32 length, Int32& dataLength)
at System.Web.UI.LosFormatter.Deserialize(String input)
=========================
in your asp.net web application, and based on the error msg, the problem
seems due to the problem on retrieveing the correct machinekey from your
web application's confige file. When do you you find this problem and in
which application or just when accessing a certain page ?
Also, have you manually specified the <machinekey> in your web
application's configure file?
Generally, the machinekey's key value is used to help encrypt our asp.net
web application 's VIEWSTATE , FormsAuthentcation's ticket(if we use it) or
the out of process Session's sessionid:
#<machineKey> Element
http://msdn.microsoft.com/library/en-us/cpgenref/html/gngrfMachineKeySection
.asp?frame=true
Please have a further check on this and if there're any new findings,
please feel free to post here.
