DHCP error on sbs 2008

This is the second time this has happened, out of the blue I get this weird event id of 1056 cenerning dchp: The DHCP service has detected that it is running on a DC and has no credentials configured for use with Dynamic DNS registrations initiated by the DHCP service.   This is not a recommended security configuration.  Credentials for Dynamic DNS registrations may be configured using the command line "netsh dhcp server set dnscredentials" or via the DHCP Administrative tool. I check the dhcp admin console, and it is running fine. According to MS i should set the credentials for dhcp server service. I went to the dhcp console, and right click my server, clicked propertied, but there is no credentials tab. Once I click properties I automatically see advance, with two entries for database path, and backup path. What could have happened to the credentials tab? is this by design for sbs 2008?
Ever so often I get these weird network errors, then when I run the fix network wizard, nothing pans out. Someone mentioned disabling ipv6, but caused more headache than comfort, so I turned it back on.

I dont think you have an issue here. This credentials would be used if you would have DHCP server to register clients at DNS, but since 2000 clients register themselfs at dns. This only would be used if you have non windows clients or very old windows clients. Anyway if you want to configure this credentials, you must do it at the DHCP console, but at IPv4 or IPv6 level, not at server level.

Well, this a SBS 2008 server (DC and exchange) so it does function as a dns and dchp server. But, just for knowledge, how would I set the credentials at the IPv4 and IPv6 level?

As you would in 2003, but instead of right clicking the server you have to expand the server and then right click IPv4 and/or IPv6. Then chose properties, go to the advanced tab, click credentials and enter them.

Oh ok, now I get it, thanks.
Now another warning is appearing (well it happened before) I am getting this warning: BITS has encountered an error communicating with an Internet Gateway Device.  Please check that the device is functioning properly. BITS will not attempt to use this device until the next system reboot. Error code: 2147747073.

Well, it kind of worked (solved) itself. The funny thing is, it comes and goes; this is not the first time is has happened. The first time it happened, I ran the fix my network wizard, and it fixed it. This time the wizard did not find anything. So, what do I do, ignore it, and wait till it happenes again?

Well. as i said before i dont think this is an issue. I have several sbs and all of them have this warning, wich happens when the server checks its dhcp settings. If you dont have any non windows machines or very old windows machines you can ignore this. If you dont want to ignore, then preoceed as inicated before and enter the credentials.

Ok then, I will do as you advised and ignore it. Hope not out of line here, but can I pay you to have a look at my server?
