Windows Domain Membership | McAfee Web Gateway

Hello everybody, I have this Issue and i'm a little confused.

To make it quickly, I have the mentioned solution (Mcafee Web Gateway) when I want to connect the domain on the config, (Make a join into the AD) The connection works fine, but, 1 sec after, the state of the connection falls.

I tried reinstall the McAfee solution, test with another installation and version, and nothing works, so.. I think its an active directory configuration thing..

Microsoft Windows Server 2003 Standard Edition Sp2
AD version: 5.2.3790.3959

If anyone have any idea I will take it grateful :)

If the connecting is successfully made then the state of the connection drops or fails it is probably not an Active Directory issue but more of a Network related issue between the DC/s and the McAfee Appliance.

I would be checking the firewall logs to see if you can find any details. I am assuming that you have your McAfee in the DMZ and your are trying to authenticate to it with your AD on the internal network.

If that is the case check the firewall logs/rules.

Thank you for the quick answer Will ..

It is a laboratory environment, so the Web Gateway isn't in a DMZ, it's all on the same LAN and shared the same network segment.

There is no firewall in the configuration.. (except, Windows Firewall and it is Disabled)

Can I check the connection with any tool?

Regards.

What you might want to use in that case would be WireShark. This will allow you to analyze the packets when the authentication/connection is taking place. That is really the only method too see what is happening in real time. You can also check the domain controller security logs as well to see if anything is logged in there when the connection is dropped.
