You receive a "The security validation for this page is invalid" error message when you try to check out a document in a document library (828811)
The information in this article applies to:
- Microsoft Windows SharePoint Services
SYMPTOMSWhen you connect to a document library in your Microsoft
Windows SharePoint Services Web site, click a document that you want to check
out, and then click Check Out, you may receive the following
error message: The security validation for this page is
invalid. Click Back in your Web browser, refresh the page, and try your
operation again. When you click Back in your Web
browser, refresh the Web page, and then try to check out the document, you
receive the same error message again. As a result, you cannot check out the
document from the document library. CAUSEThis problem occurs if both of the following conditions are
true:
- The Windows SharePoint Services Web site is configured to
use Anonymous Access in addition to another method of authentication, such as
Basic Authentication.
- You connect to the site and check out a document in a
document library before you authenticate to the site.
RESOLUTIONTo work around this problem, authenticate to the site before
you check out the document. To do so, click Sign in on the
home page of the Windows SharePoint Services Web site, type your user name and
password when you are prompted to do so, and then check out the document that
you want from the document library. STATUSMicrosoft
has confirmed that this is a problem in the Microsoft products that are listed
in the "Applies to" section of this article.
