RE: Windows Firewall blocking LSASS, causing DCOM launch error



Hi Paul,

Does the 2003 SP1 server have more than one network adapter, even if it is
disabled? Is Routing and Remote access enabled on the server?

Have you checked your DCOM security configuration on Win2003 SP1? Win2003
SP1 introduced the new "Distributed COM Users (Built in Group)". I see one
internal similar case was resolved by adding the user into the "Distributed
COM Users" group so that the user has the "remote activation" permission.
Can you give it a try?

The article below contains more details of the default DCOM security
setting for various users and the security enhancement of Win2003 SP1:
"DCOM Security Enhancements in Windows XP Service Pack 2 and Windows Server
2003 Service Pack 1"

I will wait for your further information. Thanks.

Best regards,
Jeffrey Tan
