We use a ticketing system called HEAT. All of a sudden we are having issues with the self-service. To get it going again we have to restart the w3svc service. There is an application in the virtual direction called Heat Self Service. At random moments we are unable to access the heat self service console. This system has been running fine the last four years, now all of a sudden it is acting funny. We have to restart the w3svc service. I noticed in the log that was an error relating to unable to impersonate anonymous........Doing some digging I found some website mentioning w3wp.exe. Running c:\windows\system32\cscript iisapp.vbs yielded no results. Does that mean that w3wp is not running? If so, and I get change management to turn it on, will I possibly find why the application might have stopped working? I sense the self service goes down because it is losing connection to the database server. There is no dedicated service for the self service. The vendor is not offering much help with the application. By the way, the server is 2003 running IIS 6. I have not found a clear explanation what the w3wp does. From what I gather it tracks request. But does it log error that may tell why it possibly stopped working?
