Hi all I am running exchange 2000 ent. sp3 on win2000 advanced sp3. all security hotfixes are applied (pre sp4) I am getting eventid 7031 on information store every 10/12 hours. I got Nav 7.6 as antivirus client (exlude relevant folders) I got Backup exec 8.6 installed I got Navmse 2.5 installed The server is a member server only(not ADC). all Q about Sp2+norton antivirus + IIS problems and code red have been tried and didnt helped(maybe it is a virus but not code red 2 like on microsoft Q). the only service that is stopping is Information store(event 7031). there is no problem starting it again automatically (soft recovery- takes couple of minutes-I have 50GB of databases 16 priv 1 pub). I didnt find any problem with databases (online defrag is running periodically) I was wondering if any one had this problem recently since there is no relevant q to solve it . All 3 major documents was tried and have failed (on last 3 nights). maybe there is problwem with any software mentioned above or recent Hotfix?
