Net Time uses the old NetRemoteTOD API, so you're talking LANMAN APIs & NetBIOS name resolution stuff here, I have some old notes[1] on NetRemoteTOD but much of it seems to have disappeared from MSDN.
[1] For computers not running the time service, when they issue a NET TIME command without any parameters the clients issue a NetServerEnum to enumerate the servers from the browse list (yuk) with the TS (timesource ) flag. E.G.- When you run NET TIME without the /domain option, the workstation will iterate through the list of time sources in the browse list, and contact the first one encountered. Since NBNR is dependent on the protocols installed, client node-type etc I'd just be guessing how you are resolving with out a sniffer trace[2]. I'd have to ask again why you are using net time in a 2K3 environment unless it's just an intellectual exercise, if that's the case see [2] :-] ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Wyatt, David Sent: Thursday, May 25, 2006 3:11 AM To: [email protected] Subject: RE: [ActiveDir] NET TIME command OK, so are we saying that WINS (yes, we have a WINS infrastructure) is returning the SPOKEDC (maybe alphabetically too???) -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Free, Bob Sent: 24 May 2006 18:17 To: [email protected] Subject: RE: [ActiveDir] NET TIME command Net Time is using the <gag> Browser Service to determine the timesource in the scenarios you outline so all the foibles of the Browser mechanisms come into play. You would be much better served to use w32tm to troubleshoot time issues in an AD environment. IIRC, what you are seeing in the first example is the first system to answer that is advertising the TS flag and the second is your DMB (Domain Master Browser) That's based on old recollection since I stoped trying to deal with browser issues a long time ago :-) If you checked them with browstat, I bet the browser flags for them look like this- \\SpokeDC <file://\\SpokeDC> NT 05.02 (W,S,BDC,TS,NT,BBR,DFS) \\HubDC <file://\\HubDC> NT 05.02 (W,S,PDC,TS,NT,MBR,DFS) ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Wyatt, David Sent: Wednesday, May 24, 2006 9:20 AM To: [email protected] Subject: [ActiveDir] NET TIME command Seem to have an odd issue when using the net time command... Scenario: * Windows 2003 FFL, single domain, single forest * Hub/spoke site topology, London hub, other offices spokes I have logged onto a Windows 2000 Pro desktop (that is joined to domain) in the hub site. Open command prompt and type net time. After a pause I get the following: Current time at \\SPOKE DC <file://\\SPOKE DC> is 5/24/2006 5:11 PM The command completed successfully. If I run the command net time /domain:DOMAINNAME I get: Current time at \\HUB DC <file://\\HUB DC> is 5/24/2006 5:12 PM The command completed successfully. Why is the first command getting a reply from a spoke DC and not the hub DC? Is this expected?
