Thanks again but these do not appear to apply. Here's why:

• Sorts in Explorer are fast
• My Windows Search service can't be turned on
• I get Error 2, not Error 5
• Chkdsk returns no errors
• Defrag runs fine
• In Explorer, when I type a search term in the upper right hand box, the search does run. But as stated above, Windows Search service can't be turned on and none of the Advanced features are available. And, in Outlook 2010, entering a term in the Search Inbox search field results in an endless loop search that never finishes and produces no results.
