is there an example of setting the Identity in IIS for a Custom User in an Application Pool using command line or powershell script?
You can use the following appcmd.exe command line to set an identity in IIS for a custom user in the applicationpool.
appcmd.exe set config /section:applicationPools /[name='APP_POOL_NAME'].processModel.identityType:SpecificUser /[name='APP_POOL_NAME'].processModel.userName:DOMAIN\USER_NAME /[name='APP_POOL_NAME'].processModel.password:PASSWORD
Here is my test steps and result:
1.Run cmd as administrator
2.Change directory to the location where appcmd.exe resides (c:\windows\system32\inetsrv):
cd %WINDIR%\system32\inetsrv
3.Then enter the appcmd.exe command line, you need to replace the content in the red box.
4.Then you can see that the application pool identity is successfully set as a custom account.
Hope my answer can help you!
