There are several KB articles that talk about that error:

Please read all three before taking action.

After checking those articles out and going into the reg key on the Exchange Server:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\Exchange Provider\DS Server

There is nothing.  The Exchange Provider folder is there, but there's nothing to do with a DS server...Could that be the problem?

Well, the LegacyDN names are different between the System Attendant and the address Templates, but it won't let me edit those locations....Any ideas?  Hopefully this will fix the issue....Thanks.

If I follow these instructions:

"Look for orphaned Display-Templates. To do so, you have to use ADSI Edit.

WARNING: If you use the ADSI Edit snap-in, the LDP utility, or any other LDAP version 3 client, and you incorrectly modify the attributes of Active Directory objects, you can cause serious problems. These problems may require you to reinstall Microsoft Windows 2000 Server, Microsoft Exchange 2000 Server, or both. Microsoft cannot guarantee that problems that occur if you incorrectly modify Active Directory object attributes can be solved. Modify these attributes at your own risk.

To look for orphaned Display-Templates:
Start ADSI Edit, and then locate the LostandFoundConfig container in the Configuration container:
CN=LostAndFoundConfig,CN=Configuration,DC=Domain,DC=com

Right-click the orphaned Display-Template, and then click Delete.
After you delete these entries, use Active Directory Sites and Services to force replication throughout the domain."

When I do that, I see nothing that says "Orphaned Display Templates" or anything, however once in the LostandfoundConfig container, there are about 7 things in the right hand pane....Should I delete all these things (Addresses, Address List Container, Administrative Groups, etc...)?  If it's in the LostandFoundConfig is it safe to delete?

I am the ONLY domani admin, exchange admin, etc....I have full rights.  I was trying to edit them by typing right there in the box, but maybe there's a different way to do it??

Not really.  Domain admin doesnt have access, by default, to the configuration partition.  That's an Enterprise admin task.   To change a value, you enter the new value in the "edit attribute" field and click "set".  Please make sure you have a good backup before you change anything.

Ok, here's what I've found, and I CAN edit them now if need be.

The Organization name is the same when comparing System Attendant/legacyExchangeDN with Addressing/Address-Templates/legacyExchangeDN...HOWEVER, when checking Addressing/Address-Types/legacyExchangeDV and Addressing/Display-Templates/legacyExchangeDN, there ar NO values (Value not set).....Should I add values there, and if so, what should they be?  Could that be what's causing this?  It doesn't look like I'm getting the 9126 errors in event viewer any longer, however clients still can't download any kind of offline address book....They get an error saying something to the effect of "Having trouoble connecting to the Exchange server"......Thanks.

It would seem, based on the article above, that the values should match.  I would leave it for now since your problem has changed.  Can you please post the exact error you are getting when downloading the OAB?

Lol....Well, I think I figured that one out myself.  I had to configure my offline folder settings (It's been a while ;)), then I tried to download it and got no errors.  I *think* the problem is solved...Thanks for all your help, it is MUCH appreciated.  

Nice.  It's my pleasure, but I'm sorry your problem went on for so long.  I'm glad we didnt get and change any settings first.  :)
