Microsoft Office 2000 (personal folders)

My client backed up his files on a Windows Nt file server while I reloaded his computer with Win2k. Afterwards he was able to open up all his files just fine except for his 2 .pst files. I copied thoses same files onto my computer (my documents directory) and opened up Outlook to try to open up the files. I went to tools>services>add>personal folders>and pointed to the .pst file. I received an error stating “Errors have been detected in the c:\Documents and Settings\irigoya\My Documents\(filename).pst Quit all mail-enabled applications and then use the Inbox Repair Tool. ” Can someone please enlighten me and tell me where to find the Inbox Repair Tool? Thanks
