Title: RE: Securing Permissions on NT Event Log

I sent this earlier, but I think it got lost in the messages from yesterday.

 

Does anyone have a clue as to what causes the following event and how to keep it from happening?  I found the write-up in the MS Knowledge base, but it doesn't help much.

 

Event ID: 5781

Source: NETLOGON

 

Dynamic registration or deregistration of one or more DNS records failed because no DNS servers are available.

Data: 0000: 2a 23 00 00               *#..

I have two Win 2K servers acting as general-purpose servers (DNS as well) servers to the Internet for a number of domains.  All the DNS zones on both servers are AD enabled.  The DNS servers have forwarders enabled, which point to the DNS servers of my ISP.  The servers have dual Ethernet connections: One Ethernet is on a segment (209.42.32.x) which connects to the Internet via an SDSL line, the other is on a back-end LAN (10.1.x.x).  Both servers are connected to the SDSL segment and the back-end LAN.  Both servers are hosting web, ftp (via IIS), and one server is hosting mail (via Exchange 5.5).  Everything seems to be running fine, but the event message is troubling.
