Null Sessions


Recommended Posts

I am trying to determine what is causing all of my W2K servers to be allowing

"Null Sessions".

I have changed the "restrictanonymous" reg values to 2 and check the local

policy settings on the servers per this ms doc:

http://support.microsoft.com/default.aspx?scid=kb%3ben-us%3b246261

 

Evidently something is still causing these servers to respond to "Null

Sessions". The Windows 2003 servers that have the same GPO settings do not

respond to the Null Session requests?

 

Anyone ever see this before?

 

Thanks!

Dan

Make sure you have rebooted the server and testing correctly (i.e. receive

the list from Linux system that is not in your domain).

 

See how it traces in the security log.

 

And do not cross-post.

Do you have URP1 for Windows 2000 SP4 installed??

Also, couldn't it be using an alternate named pipe for that??
