In the last 2 weeks my server became not responding 3 - 4 times. When we come in the morning we see the server in not responding state. I have a windows 2000 server running apache tomcat for a java based application . The database is oracle 8.1.7. I have scanned the system with Norton AV and Stinger. Couldnt find any viruses.
When I check the system log I could see some messages like 'the last shutdown was unexpected'.
It has also some alerts like unable to start the IISADMIN service because either it is disabled....
somthing like this.
Kindly provide me some informations on this cause we are an application service provider andwe cannot afford to have a system downtime even for a single minute.
The server is hosted behind CISCO PIX with ports 80,81,82 and 443 open.
