I am running Windows Server 2000 with IIS for our MES application. I have the same application running on 3 different application servers - all Windows Server 2000. Recently, one of the application servers has had the dllhost.exe process - running under IWAM_(servername) - growing until we can no longer access the application. I can manually restart IIS - which takes care of the problem. I looked at installing the IISRecycler tool - have not yet done. Is there anything else I should try or look at?
