inetinfo.exe mem usage is very high almost it reaches 100% in my exchange sever 2003 can tell me howto reduce the mem usage from 100% 40 or 50% . Physical memory is 2 gb ,remaining hardware no issues.

Hi Vijay,Is this a spike or it keeps above 50% all the time?Make sure you are updated with latest SP and hot fixes.And also try mother of all troubleshooting step, A REBOOT. Give it a reboot and see if that makes a difference.Also, try going into the properties of your Virtual SMTP server and limit the number of connections that it can establish. Clear the queues and tighten security on the connector. Also make sure that none of your users have been bitten by a mm worm/virus and their machines are trying to send out heeps of email.Are you using any AV like GFI? http://thebackroomtech.com/2007/05/25/troubleshooting-the-inetinfoexe-process-running-at-100-utilization/Raj

If you use scan mail then stop and start it and see effect..Anil

Hi Raj,I was clear the queues and tighten security on the connection , i was scan the entire domain network clear the worm and etc virus files, still it 's showing 100 % . i was reboot the server . Os patchesalso till date updated.RegardsVijay

Shut down the AV engine for a while , reboot the box and see if that makes a difference. Which AV you are using on exchange server?I have seen these issues with some misconfigurations on AV.Raj

Hi Raj, In exchange we are using Virus Scan Enterprise 8.7.0i Ver. But there is no misconfiguration on Av. Even Domain also Same Av. Regards Vijay

Can you disable all the services and then reboot the server and see the result.Raj
