This property specifies the password for the account that IIS uses by default as the COM+ application identity for newly created IIS out-of-process applications. The values of this property and its companion property, WAMUserName, are set when IIS is installed, and match the password and user name values in the Microsoft Windows user account (IWAM_MachineName, where MachineName is the name of the machine on which IIS is installed) established at the same time.
Important
It is recommended that you do not change
the value of this property. If you do, the Windows account password
must be changed to the identical value, and you must also
synchronize existing IIS out-of-process application identities by
using Component Services to edit the user name and password values
found on the Identity tab of the property sheet for each
package.
In-process applications are not affected by these property values.
