Our Information Store got corrupted!! We used NTBackup to try and restore it and it told us that it was unable to resotre the Priv.edb and Pub.edb. We checked permissions and we renamed the Priv and Pub to try and get it to work and also removed the logs. We were restoring to the original server. Does anyone know if there is anything else we can try to get it to do the restore?? We are using Exchange 5.5
