Re: Is The RPC a Protocol or a winXP-Service?

In newer versions of Windows (2000+ I believe) it also listens on the Active
Directory port (445), and perhaps others as well (I believe IIS even listens
to it on port 80!).

Otherwise, I agree with the others - it's a (proprietary) Protocol used by
many Services listening on many Ports.

IMHO it is a service. RPC means RemoteProcedureCall and offers
a remote Client to execute procedures/functions on the machine
offering this service.
Which procedures/functions and what a request to a rpc-service
looks like has to be defined in a protocoll.

So: protocoll says "how to use the service" and rpc is the service.
In case of 137/139 under ms-windows it is netbios-ssn which offers
shares/ressources over network!

Please correct me or add-on whatever i forgot...

What is The RPC exactly  ?
The RPC  is a Protocol  or a winXP-win2000-Service or a Port?
www.Rabertgraham.com  says that it is a Protocol .
My windows says it is a Service .
Some other articles says that it is a Port .

And another questions :
www.Rabertgraham.com in its FireWall-FAQ  says these lines:

[""Various errors with :
Some servers are misconfigured to map this address.
On the other hand, it is also a hacker technique
to cause names within the hacker domain to resolve
to addresses within a company (including localhost/""]

And my question is :
How do they (Crackers) do that ?
