Resolved. It was actually firewall issue. Our network guy had to open the port on the router.

Actaully, I didn't modify the GPO since it would impact hundreds PCs. I do have remote admin enabled on the problem machines. Actually, I manually enabled it by using the script you recommended in the post. http://www.lansweeper.com/forum/yaf_postst2967_Scan-over-VPN.aspx.
But most of our PCs have remote admin disabled and the active scan is working fine with them.

Enabled Remote admin mode but got the same error. I checked other PCs with success in active scan and they actually have the Remote Admin mode disabled. So, "Cannot connect to DCOM port 135 : Firewalled" might be caused by something else ?

It might take some time for the GPO to be active.
Do you have remote admin enabled on the problem machines?
