DescriptionIISADMIN service recreated an account IWAM_<Machine>. For additional information specific to this message please visit the Microsoft Online Support site located at: http://www.microsoft.com/contentredirect.asp.
Event InformationIt is reported that, if you renamed your IIS servers computer name, then this event will occur. The main reason for this problem is related with IIS user accounts IUSR and IWAM.Here a solution for solving this issue.you need to edit the IIS metabase if you really want them to reflect your machine name. After searching multiple sources (including this one!) I found the best workaround:
- 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"
- Follow MS Q297989 to get the passwords for IUSR & IWAM.
- Enter the new IWAM user name and the password in the Identity tab of the IIS Out-Of-Process Pooled Applications under Component Services\Computers\My Computer\COM+ Applications.
- Type IISRESET to restart IIS services.
