I have a login page.when i click on login button it gives me postback error as
Invalid postback or callback argument. Event validation is enabled using <pages enableeventvalidation="true"> in configuration or <%@ Page EnableEventValidation="true" %> in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation
When i set the enableeventvalidation="false" it gives me oraops10.dll error.Please help me out to resolve this issue.Also this websites works fine on my pc.But when i shift it to another pc iis server i get this error

The issue is in the Oracle client DLL (oraops10.dll). You probably have a different or missing version of the oracle client installed on the machine that doesnt work.
