Port used for Active Directory authentication against Domain Controllers

Hi All,

I'd like to know if anyone can let me know which IP address or server that is currently using Active Directory integrated domain authentication ? I'm running Wireshark for one week to get the data of which servers is using AD authentication mode.

Is htere any port number that is used by the application to conenct to the domain controller for DomainMode enumeration ?

Because when I look into the Event viewer in all of the domain controllers, I'm overwhelmed and confused myself.

Thanks,

I'm raising domain functionality level from 2003 to 2008R2 Will.

So I need to know which server it application is authenticating regularly against my AD domain controllers.

Any .Net framework older than 4.0 will have issue in 2008R2 domain functionality level.
This is the best money I have ever spent. I cannot not tell you how many times these folks have saved my bacon. I learn so much from the contributors.

Where did you read that upgrading the functional level affects. NetFramework lower than 4.0? Upgrading the functional level only affects the Domain controllers and the features that are "unlocked". It does not affect members servers or workstations.

So I wonder if Exchange Server 2010 SP3 needs to be restarted as well and apply the patch or hotfix too.

Will,

Luckilly all of my Exchange Servers 2010 SP3 are running on Windows Server 2008 R2 non-SP1 and also all of the Applicatiopn Servers running Windows Server 2008 R2 SP1, so I guess I do not need to apply the patch above :-)

Also I do not even need restarting Exchange server services after the raise.
