This property specifies the account user name 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, WAMUserPass, are set when IIS is installed, and match the user name and password values in the Microsoft Windows user account established at the same time. It is recommended that you do not change the value of this property. If you do, change it to a valid Windows user account, and change WAMUserPass to the corresponding password for the new account.
Note
Changes to the value of this property and
WAMUserPass may disrupt the operation of existing IIS
out-of-process applications. You can synchronize 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. See WAMUserPass for additional information. In-process
applications are not affected by these property values.
