SYMPTOMS
When you view the home page of a Microsoft Windows SharePoint Services site, you may receive one of the following error messages:

Web Part Error: Cannot deserialize (convert an XML stream back into an object) the Web Part on the server.

Web Part Error: One of the properties of the Web Part has an incorrect format. Windows SharePoint Services cannot deserialize the Web Part. Check the format of the properties and try again.



CAUSE
This issue may occur when permissions that Windows SharePoint Services configured on the Windows Temp directory were unintentionally reset, possibly when you upgraded your operating system.



RESOLUTION
To resolve this issue, make sure that the following permissions are configured correctly:

Windows directory

\Temp

Administrators - Full Control

SYSTEM - Full Control

STS_WPG - Read, Write

Network Service (for a domain controller only) - Read, Write

\system32\logfiles

STS Administrators - Full Control

SYSTEM - Full Control

STS_WPG - Read, Write

Network Service (for a domain controller only) - Read, Write
