Mac on windows domain DNS problem?

Long question, as many details as possible to help...

We have been adding Mac's to our Server 2003/2008 network without trouble...we thought.  Installing an antivirus for Mac's has brought out an issue.  Apparently when we set up a mac to join to our domain, the mac, is getting an old computer name(wins, netbios) that for some reason still seems to be in our dns.  We name the computer (ex. L1002-AP-001) but for some reason in the WINS tab of the network window (Mac OS X 10.6.8) it is getting an old name and using that, even though we name the computer something else (L1002-AP-001)?  Now that I know to check this tab, I can go in and rename the computer to what it should be, but have setup approx. 40 mac's without knowing this was happening.  Now, I can go back on the 40 or so machines and try to change the name back to what it should be, but...some of the 40 have "grabbed" for a lack of a better term, other mac's names that weren't "assigned" their correct name.  Example, I have a mac that is named L1102-AP-067 but it's WINS/NetBios name is L1110-AP-055 and a mac that's WINS name is L1102-AP-067 but it's real name is L1108-AP-097.  So if I try to "re-name" the L1102-AP-067 mac to L1102-AP-067 it won't let me because according to DNS/WINS it is already being used...(L1108-AP-097's WINS name is L1102-AP-067?)  Clear as MUD???  How do I fix this?  I would really like all of my Mac's to be recognized by DNS as their "REAL" name.  Of course all of the PC's don't have this problem, just the Mac's.  Again, sorry for the confusion and the length of the question but, this is how I can best describe it.

I know it is a pain but you can delete the DNS/WINS records and then create them manually.  You will also want to create a DHCP reservation so the IP doesn't change.  

I had this happen before and found that by deleting the MAC computer account from the domain re-adding it helped but that was usually just a temporary fix.

Hi there;
I used to have hundreds of MACs in my AD and i never had such a problem. Just to make sure, are you changing the name of the MAC under network/Wins/netbios name only or you are changing it under the sharing applet also? Cause Active directory will use the hostname in Sharing tab and not the netbios name under the WINS tab  in the Network applet. ANyways, during the joining process, active directory will show you the computer ID of the macintosh that will be used in active directory, that is the real hostname and once joined it will restet the netbiosname under WINS to whatever was your Computer name under Sharing.
To avoid this, simply make sure that your hostname under WINS and conputer name under Sharing are a match.
Let me know.

Yes, that is what I have discovered...after the fact.  Now, how do I get all of the Mac's to their actual names since some of them are using the names I need to change to?  Do I have to gather all of the Mac's and unjoin them from the network and then change their names and then rejoin them?  I sure hope not, that will be a REAL problem...

Well, the ones that are not using the correct names, you will have to unbind them, rename and bind back again. There is no workaround about this one. Sorry.

So, going forward, make sure all names are correct before joining to domain?

Commented:
Exactly, especialy what is displayed as computer ID while you are binding the machine to AD. If you see anyhting wrong with that ID, go back fix it, then bind.

Commented:
I hope you will read this. One last thing, when you change the name of the MAC under sharing, click the edit button and check if the name is a match, because you can have two different names under the sharing tab which can cause lots of problems.. Pay attention to that.
