I have IPM 2.6 installed on Win2000. Everything was working fine and we used to take weekly reports on every monday. This monday i wanted to take a report for the last week and it gave me an error saying ' Cannot get Operation Statistics for the given time range'. We restarted the server and since then we are able to generate the reports from that time onwards. Still the reports for that particular week are not there. There is nothing in the server info log or the ipm troubleshooting log. Please guide me as to how i should troubleshoot the issue.
