When you try to sync a SharePoint site to a SharePoint workspace, you receive the following error:
A content type with invalid identifier number was detected during schema analysis. This list or library may have invalid content type definitions due to a previous server upgrade.
In this error, number is a hexadecimal value.
The “content type with invalid identifier” error indicates that a content type on your site is using an identifier that isn’t standard in SharePoint 2010. This most often occurs when a server has been upgraded from Windows SharePoint Services (WSS) 2.0, but it can happen in other situations.
For example, all SharePoint 2010 identifiers for a Document content type should start with 0x0101 (System 0x, Item 01, Document 01), but in WSS 2.0, you might have created a content type named "Document" with an identifier that did not match this pattern. The upgrades from WSS 2.0 to WSS 3.0, and from WSS 3.0 to 4.0 (SharePoint 2010) would leave this identifier unchanged. However, the old identifier is not valid for the content type "Document", so SharePoint Workspace cannot assume that items with this identifier have the characteristics of a document.
You may be able to resolve this by associating the content type to a valid identifier. SharePoint has many content types. The following example assumes that a Document Library is not syncing and that the Document content type in the document library is not using the standard Document content type.
First, allow management of content types. To do this, follow these steps:
For security reasons, you may want to disable management of content types once you have tested your changes. To do this, follow these steps:
