Ever get annoyed when your in debug mode that it times out in a measly 90 seconds? This is easy to change. This assumes SharePoint 2010 and IIS7, but should be applicable in a SharePoint 2007 scenario as well.
1. Open IIS Manager (enter InetMgr.exe Start search textbox)
2. Identify the IIS web site and the application pool for the site you are debugging
3. Go to the app pool, right click and click Advanced Settings
4. Change both Ping Maximum Response Time and Ping Period to something really high. I changed them to 5000 seconds in my case.
Now you won’t time out while debugging! One more frustration removed from the SharePoint development experience.
