I looked in the DLL the first time I responded which is why I mentioned DNSAPI.DLL. When I worked on the code last night I had all the info I needed, just had to wrap the calls and format the data properly. The fact that it would be easy and was for some old friends is why I worked on it. It really didn't take any serious thought from that point, just execution. Even you, possibly, could have done it, I imagine, if your pets didn't spike your drinks to assure a peaceful sleep. :)

DnsModifyRecordsInSet and DnsReplaceRecordSet API calls. These are out of dnsapi.dll. If you look at netlogon.dll with Dependency Walker you will see 10 imports from dnsapi.dll including the two above. Looking at their defs they have the ability to add/delete/clear/replace records between them. So that is what I tested and got working. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Sunday, January 15, 2006 1:44 PM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] LDAPS SRV Records?

Hey Brandon. The call that something like IPCONFIG /REGISTERDNS uses is *probably* I_NetLogonControl2 with NETLOGON_CONTROL_FORCE_DNS_REG. That just tells a DC to reregister its records. Nothing to do with what records are actually registered for a DC. You definitely don't want to look into hooking into NETLOGON. First off it would have to be on the DCs which would be very difficult to get approval for even if the code could be written in a secure and stable way (doubtful since you would have to do code injection). I personally wouldn't allow it, there is no reason why this can't be done from another machine. Of course you could try to script around dnscmd or nsupdate. The dnscmd may be MS-DNScentric, I do not know. If it is, it may not work in your environment. Unless there has been some serious changes in DNS there nsupdate works great. I used to do a lot with DNS via perl scripts and nsupdate. Vern et alii should have some perl scripts that I left behind that show how to use nsupdate. You could set something up with the scheduler service. Some job that runs every hour and checks to see if a certain DC (or the local DC if you can get it cleared to get it to run there) has LDAPS available and then registers the appropriate LDAPS record. At a lower level, looking about, you may be able to use the API in DNSAPI.DLL, unfortunately most of that API seems to be undocumented (when comparing the exports with MSDN) but DnsModifyRecordsInSet and DnsReplaceRecordSet look extremely promising... I would be willing to bet big that those are the calls MS is using under the covers in NetLogon. It is Windows 2000 and better so you should be safe for any machine you want to run from. Note I was pinged on this offline from someone else there and put in a DCR for registering LDAPS records back in December. joe ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Bernier, Brandon (.)

Does anyone have an idea which Windows API does the DNS registration of SRV records for DCs? I'm very curious as to if that is a public method. The purpose is I'm looking into how feasible it is to write a Windows Service that hooks into netlogon and registers secure LDAP SRV records as needed provided the DC's can speak LDAPS. Think it's a horrible idea? Could be done better? Let me know what you think. I know the ultimate solution is a DCR, but like I said..I'm just brainstorming ideas. -Brandon List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/ List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/ List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/ List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.mail-archive.com/activedir%40mail.activedir.org/
