Windows 2003 server failing to search on a network share when looking for "A word or phrase in the file"

I've got a Windows 2003 terminal server and my users often search though remote text files for order numbers. We previously had a windows 2000 terminal server and the normal windows find dialog worked fine. Now with windows 2003 we always get zero results returned. Is there anything I need to tweak to get this working again?

Indexing services is enabled, everything else is on the default settings.

• I think you need to adjust the file types that are being indexed on the server. Here's a MS KB article that references the issue.

  splattne : I agree. Blog entry here: http://weblogs.asp.net/owscott/archive/2008/04/04/enabling-xp-and-windows-server-2003-to-search-all-files-types.aspx

  wizard : The files are on a non indexed remote server which through me for a loop. But the solution works, thanks!.

• I found my solution, even with indexing disabled I had to go to "indexing service" and enable "Index files with unknown extensions" and the files started showing up in the searches.

  I used Microsoft KB Article 209173: Using the "A word or phrase in the file" search criterion may not work for reference.
