I have a dllhost.exe running under the unsername "system" and I have two more dllhost.exe running under IWAM_myusername where as myusername is the name of whom is logged into the computer. I seem to cannot find any information on IWAM pertaining to Windows XP. I see a lot of Windows Server results and adding 'Windows XP' to the query results in the same Windows Server results and one Windows 7 result. No Windows XP. Should I be worried? What is a IWAM?
