Reading the Group Policy Preferences Overview Whitepaper from SDM software, I just notice an interesting prerequisite for using GPO Preferences – XMLLite.
XmlLite Runtime Files
The XmlLite runtime file, Xmllite.dll, is integrated into the following operating systems and products:
- Windows Server 2008
- Windows Vista
- Windows Server 2003 with Service Pack 2 or later.
- Microsoft Internet Explorer 7.0 and later.
The XmlLite runtime is also available as a download from the XmlLite Update Page for the following operating systems:
- Windows Server 2003 (32-bit with Service Pack 1 or x64 Editions)
- Windows XP (32-bit with Service Pack 2 or x64 Editions)
So if you want to use GPO Preferences on a Windows XP SP2 client with Internet Explorer 6, you will need to install the XMLLite runtime package for XP.
