SYMPTOMS
In the Microsoft .NET Framework 1.1 Service Pack 1 (SP1), when you use virtual directories that are not configured as applications, you may receive view state error messages that are similar to the following:

The viewstate is invalid for this page and might be corrupted.



CAUSE
This problem occurs because the template source directories on two computers do not match. For view state validation to work correctly, the source path for both computers must match.
