Title: RE: Site Link Bridging

Having site link bridging should not have resulted in DCs from different sites registering in the same site unless their wasn't full coverage for the domains or if one of the sites didn't have a GC. Something isn't right here.   Not that that might not be a response they heard from an architecture review though, the quality of those reviews/health checks/RAPs and the guidance given at the end vary drammatically in quality based on the analyst involved. I have found in general though the AD folks can't give any good advice on Exchange and the Exchange healthcheck folks can't give very good advice on AD and MSFT doesn't have an all consuming healthcheck that takes all of it into account. So you end up getting a case of one healthcheck pointing at the other for sources of problems. Usually what you see is the AD folks saying everything is fine and the Exchange folks saying AD is in trouble but not being able to point at anything in particular.     joe   -- O'Reilly Active Directory Third Edition - http://www.joeware.net/win/ad3e.htm      From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Tuesday, May 09, 2006 6:41 AM To: ActiveDir@mail.activedir.org Subject: [ActiveDir] Site Link Bridging A friend of a friend when designing a new forest was asked to disable site link bridging (forest wide) based upon the reasoning given below.   I fail to see any connection between the description below and site link bridging.   Does anyone see how these issues could be caused by bridging and furthermore, why the issue would have been resolved by disabling bridging???   neil PS I don't necessarily believe that MS really did suggest disabling bridging would help - I merely copy/pasted the original thread :) ___________________________ Neil Ruston Global Technology Infrastructure Nomura International plc Telephone: +44 (0) 20 7521 3481      We had an issue where the Domain Controllers in the New York site and New Jersey site were being registered under one site in DNS. This was causing users to authenticate to DC’s over the WAN link as well as Exchange servers using GC’s over the WAN link. This was causing some delays in users logging on as well as outlook being slow using the address book.  Also servers were synching up their time with DC’s in other sites causing w32 time errors at night and during the weekend while backups were running. This caused some servers to have their time offset be 3-5 seconds.  We had Microsoft on-site services evaluate the infrastructure and they recommended that we disable the Site Link Bridging to increase performance of the above issues.   PLEASE READ: The information contained in this email is confidential and intended for the named recipient(s) only.
