Exchange 2000 crashed

Hi,

I’ve a big problem with my SBS 2000 server: exchange 2000 and isa server are not starting. The os seems to work correctly, but I cannot start Exchange srvr. I tried to reinstall it, but nothing changes. I need to retrieve the messages, I don’t have a backup but the mdb and str are intact. Is there any way to get my messages back??

Thanks
