Hi
Im a little confused to the answer to the related question..   I too have the same issue as the originator of the message and would like to disable NULL base queries on a 2003 AD server.


however, I read on http://technet.microsoft.com/en-us/library/cc781273(WS.10).aspx 
 that ..."By default, Active Directory does not accept null session queries".......... meaning to me, it is turned off be default.


The accepted solution to this original question says that you cant turn it off and if you did AD would break....

I realise the link i sent is old... does anyone have the definitive answer with a link to an authoritive document ?

please note, my knowledge of this area is very limited.!

many thanks

See this article here, it refers to Windows 2000, but it references Windows 2003 further down and the changes it has made to make it more secure than Windows 2000 with respect to Null queries.
