Today after unregistered and register COM+ on our server, when I tried to start the COM+ there is an error message “Error Code 800401E4 – Invalid Syntax“. I tried to restart the server but the problem still occurred. When I search this keyword on google, thanks GOD I found the solution Whew.

I’ve got solution here.

1. Added the following key and value as noted below : KEY_CLASSES_ROOT\CLSID\CLSID
2. Set it's (Default) REG_SZ value to {0000031A-0000-0000-C000-000000000046}

It works for my problem.

Cannot Delete NTUSER.dat

Filed under: Tools — Tags: , — solihinho @ 10:55 PM


Today when I tried to remove some user profiles on my server, I got an error message “Cannot delete NTUSER.dat: It is being used by another person or program”. I’ve checked if there is an application open this file, but I found nothing. I tried remove this file using an application called “ForceDelete.exe” but still could not delete this file.

You can download tool called “User Profile Hive Cleanup Service” from microsoft. I’ve tried to download and installed this tool in my server. After installation is finish,  navigate to C:\program files\UPHClean using windows explorer. Run the exe file than try to remove the profile again. It’s working for me Party.
