Outolook 2002 mails and contacts r gone

I did upgrade my Server and my workstation. Server to winddos 2003 and Wkst to WIndows XPP.
Well, my old system [w2k] had a domain of CPSVILLAGE.NET, the newest domain is CPSVILLAGE.local, bcause we have the same domain in the Internet. What’s up is when My wkst joined the new domain, everthing was ok but all my emails and contacts desapeared. [we have several hundreds [important e-mail and contacts] What can I do to recover those files?!?! I know they are there, but how can I retrive it?!?Thnx for your help.
