Hi All, I have managed to restore an exchange 2000 server using IS only. Now I am in a situation where I couldn't start the IS service. When I start the service, event id 454 is generated with the following details "Information Store (2236) Database recovery/restore failed with unexpected error -1808". With reference to the details of 454 I checked the space on the drive which is having 24 GB left. The IS size is 14.5 app. Event Id. 8197, 7031 & 7022 is also generated. Event Id. 101, NNTPSVC warning is also generated. Any info is highly appreciated. Regards
