Title: Re: [ActiveDir] WINS

I can't recall all of the circumstances but the ones I have personally run into or been involved in seemed to be around configuring and installing things. The one that was most fun involved the MCS guys working with the Exchange admins to load something or other on some server and I looked at the trace and the server would get a DNS name back from its initial query, then it would chop it down to a short name and try to resolve against WINS. The DC it was trying to hit was a hub DC so wasn't in the server WINS architecture [1] and therefore couldn't be resolved. It was picking the wrong DC in the first place because the subnet the server was in wasn't defined and it was picking some random site. The fun part was the MCS guys had been working on it for some time and finally called me. I told them to get a trace of it and that I expected it was probably WINS and I would be on my way to take a look. They didn't believe it was WINS but as soon as I got there and saw the trace I saw the WINS failure in a couple of seconds (litterally).     Note that if you have joined namespace, i.e. DNS of AD matches DNS of servers and you have a single domain or multiple search suffixes for all domains involved, the standard process of falling through netbios/wins resolution to DNS may work for you and you are working simply by sheer happiness of that accident.      joe     [1] This is a hub and spoke with one way replication which probably will be extremely alien to anyone who hasn't run a large environment. In a larger environment (over 25 DCs) you simply do not publish all domain controllers on all of your WINS servers if you want to have a good handle on things.

It seems that exchange just might need WINS to do netbios resolution at some instance. Now what is that instance? It seems not everybody will necessarily come across that instance.   From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Van Noy, Glen Sent: Sunday, March 06, 2005 12:28 PM To: ActiveDir@mail.activedir.org Subject: RE: [ActiveDir] WINS   Just curious, where in the deployment guide does it say that Exchange 2003 needs WINS?  We are running a clustered Exchange 2003 setup and we don't have WINS configured on our domain.   glen [EMAIL PROTECTED]    The University of Texas at Dallas     From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Robert Mezzone Sent: Sunday, March 06, 2005 12:20 PM To: ActiveDir@mail.activedir.org Subject: Re: [ActiveDir] WINS Unfortunetly it does.
