Unknown Guests: IUSR and IWAN 1

[Hanuman67]

Every time I reboot, I find two users listed as Guests on my system: IUSR-(ComputerName) and IWAN-(ComputerName). They are listed as guest accounts for anonymous access to the internet. From a quich scan of the internet and local documentation, it's hard to tell what the implications of this are.

My current guess is that is has to do with internet webservice and has some security risks associated. Any other ideas? What do they keep reloading after I delete them?

Thanks.

These accounts are created by IIS, and are used for anonymous access to your web services. If you are not hosting web pages on this box, try either changing the associated services to disabled, or try removing the software (IIS).
