描述：SharePoint新建Web应用程序时提示如下错误：
解决：
1. Go to IIS
2. Select the DefaultAppPool and Go to the Advanced settings.
3. We will be prompted with the below popup.
4. Under the “Process Model” category, Select the “Generate Process Model”, Idle time out reached property would be by default “True”.
5. Make it to “False”.
6. Reset the IIS.
7. Come back to Central Administration and try creating. Now it is getting created and works as expected.
