RE: [ActiveDir] Sites with no DC

Title: Message

Leaving it up to the locator costs essentially nothing in this case.  But the result may not be very “near” to the client.   See Mark Tucker’s mail; his explanation was correct… query DNS for all DCs in domain regardless of site, order according to SRV RR priority, arrange randomly (within priority level) according to SRV RR weight, and walk the list sending LDAP UDP pings to each DC until the first one responds, waiting 1/10th of a second between each “ping”.   Since most people don’t change the SRV RR priority or weight fields registered by the DC, you get a walk of a randomly arranged list.     -----Original Message----- From: Gil Kirkpatrick [mailto:[EMAIL PROTECTED]] Sent: Thursday, October 24, 2002 5:50 PM To: '[EMAIL PROTECTED]' Subject: RE: [ActiveDir] Sites with no DC   I haven't tested it myself, but I doubt very much. Assuming the programmers used reasonable data structures internally, the calculation should be pretty straightforward. Of all the things a DC does during authentication, I suspect that site determination is one of the quickest. -----Original Message----- From: Garello, Kenneth [mailto:[EMAIL PROTECTED]] Sent: Wednesday, October 23, 2002 2:07 PM To: '[EMAIL PROTECTED]' Subject: RE: [ActiveDir] Sites with no DC How much overhead does leaving it up to the locator incur?   Ken   -----Original Message----- From: Gil Kirkpatrick [mailto:[EMAIL PROTECTED]] Sent: Wednesday, October 23, 2002 4:37 PM To: '[EMAIL PROTECTED]' Subject: RE: [ActiveDir] Sites with no DC   Hey Don,   Is this your first post to the list? If so, welcome.   To answer your question, no you don't have to create a site for each subnet. You can associate multiple subnets with a single site. Or you can leave the subnets unassigned, and the DC locator will do its best to find a DC "close" to the authenticating PC.   -gil -----Original Message----- From: Don Murawski (Lenox) [mailto:[EMAIL PROTECTED]] Sent: Wednesday, October 23, 2002 1:02 PM To: [EMAIL PROTECTED] Subject: [ActiveDir] Sites with no DC We have subnets without dc's, do you need to create a site and subnet in Sites and Services anyway for those sites?   Don L Murawski
