We are experiencing some difficulty with backing up our exchange server(5.5 on NT4.0). Through the various phases, we have had a specialist inform us that our information store is excessively large, which could be an indication of it being corrupt. To resolve this we have been informed to run ISINTEG.EXE on exchange (offline) to repair any inconsistencies. I am unable to find this application anywhere, either on the web, or on the server (as part of the install). Can anyone point me in the right direction?
