Your client application may try to create an object that uses Component Load Balancing (CLB) on a computer that is running Windows Server 2003. If that object has a proxy with a remote server name that points to the Application Center 2000 routing cluster virtual IP (VIP) that is installed on the client computer, you may receive the following error message:
By default, COM+ application access checks are turned on in Windows Server 2003. This is done to help increase the security and may help to prevent anonymous users from creating objects on the Windows Server 2003 COM+ application servers. CLB uses the anonymous account to create objects for client computers that use proxies to point to the routing cluster.
You can resolve this issue by using one of the following methods:
You can enforce security roles on COM+ method calls. You can do this to help prevent users from using the objects that they create if their account does not have an appropriate role.
