Okay, here's the situation ... and it's a little wierd. There is probably an easy way to solve this problem, I'm just not an expect with Exchange - fairly new to the admin of exchange.
We have a Win2k SP2 server running Exchange 5.5 SP4. That server crashed. When it was orginally built (not done by me) the company was named one thing ... after it crashed I had to rebuild it and entered the new company name into the org field. And now when I attempted to restore the private and public information store I get an error saying that the info store is from a different site.
So I built another server (Win2k SP2) and installed Exchange 5.5 SP2 using the old org name. But even that server still won't accept the restored information stores. I don't get an error other than a message in the event log stating the information store service cannot be started due to an unknown error.
How can I restore the backed up information store from the previous org name to the new org name. By the way, the site name and the domain name never changed - just the org name.
