Post subject: TCP port 135

I wonder if anyone here can tell me what else I need to do to close TCP
port 135 on XP Pro.

Task Scheduler is disabled (which closes 1025 completely).
DCOM ha been shut down to through Dcomcnfg.exe. Even checked in registry key
"EnableDCOM" and it's set to "N" now. So it's off.
Now, I've read that all that is left is to shut down is MSDTC. A bit
confused on how. Disabled it through Dcomcnfg.exe and the "Distributed
Transaction Service" is shut down (Can just as well be shut down through
Services MMC straight off, same thing). Reboot, and TCP port 135 is STILL
open when I scan for it with nmap from another computer.

I was on my way on renaming msdtc.exe file in both system32 and dllcache but
I'm a bit afraid to do that and test. Just might not get system running
again though it should be no problem.

Anyone knows what I'm missing to get TCP port 135 closed?

MsMittens has posted this link to closing the port:

But is there no other way, as aked in my above question?
(Don't like the idea of hexediting the dll)
