I've been following this Microsoft White Paper:
to create a segregated Global Address List, Address List, and Offline Address Book for several non-profit organizations we host exchange for however it appears that my Default Global Address List has disappeared. Attached is a screen cap of the error I receive while trying to add required permissions. The second screen cap shows the ADSI output in my All Global Address Lists container with a "phantom" Default GAL. The name shows but it does not show as an address book container. Using ADSI from a 2008 DC if I attempt to get properties there are no attributes to the list but security options show. If I try using a 2003 DC I cannot get any properties but instead get the error "An invalid directory pathname was passed".
Current severe issues are that profile creation is failing because the user cannot be found in the address list and where there is apparently cached GAL information in the Outlook 2007 client other organizations can be found but email addresses of the org in question cannot be seen.
I've seen a post that indicates re-running setup /adprep from the Exchange 2007 DVD would recreate the default GAL but I've not seen any definitive confirmation of this nor any other way to manually create the default global address list.
Any help is greatly appreciated.
