Rename IUSR IWAM Accounts

Fri, 30th January, 2009 - Posted by Administration

Problem: IIS IWAM and IUSR have the wrong server-name after a rename of the server
after VMWare/Ghosting. You want to re-create them with the new server-name because
two computers would have the same IWAM and IUSR accounts.

- Rename the IUSR & IWAM accounts to match your machine name (i.e. “IUSR_NewMachineName”)
- From a command prompt go to the \Inetpub\Adminscripts folder
- Type cscript adsutil.vbs set w3svc/anonymoususername “IUSR_NewMachineName”
- Type cscript adsutil.vbs set w3svc/wamusername “IWAM_NewMachineName”
- Type cscript.exe x:\inetpub\adminscripts\synciwam.vbs – v
- Type IISRESET to restart IIS services.

Note: Per Microsoft ( ) add the Following Key to prevent automatic recreation of the original names on boot or restart of IIS. However, if the above steps were performed successfully you should not need to do this. Further, adding this key simply hides additional problems.
