You do not receive any search results over a WAN connection from a Windows XP-based computer

When you search for files or for folders over a wide area network (WAN) link from a Microsoft Windows XP-based client computer, the search result set is empty. This symptom occurs even though the files or the folders that you are searching for actually exist. Additionally, you receive the following message:An entry appears in the event log of the client computer that resembles the following:

Event ID: 3019
Source: MRXSMB
Detail: The redirector failed to determine the connection type
