Windows 7 workstation logon slow to DC

Hi;

I found that before the computer workstation join Domain, the start up time of Windows 7 is fast, the desktop can be displayed quick.  However; once it is joined to Domian, it is slow to display Desktop after user enter user name and password, looks like the authentication process or something loading or synchronizing slow.

Can someone tell me what should I check?  I am thinking if the Global Policy caused the problem?

I am using Windows Server 2008 DC

Try doing a gpupdate /f on the client and see how long that takes. If it takes a long time then Group Policy is likely your cause. You can also try a program like Soluto that will tell you what programs are slowing your boot.

There may be several resons. If it's very slow, check that you have the correct DNS on that workstation (DNS should point to the domain controller).

A common slowdown the group policy, there are two parts of it: computer and user policy, which can have script attached. Another possible slowdown may come from the login script itself. Check if the user has a login script attahced to it and see what the script does on logon.

For group policy you should check what is attached to the computer object in Acrive Directory (or in any upper level containaer for that object) and what is attached to the user account and / or groups it belongs to.

This will give you some insight on what happens on login, maybe you can remove some things and sped things up.

Hello;

I just read some articles to mention that why the Windows 7 slow logon to Windows 2K8 DC, some articles said that if the DC is a multi-home server, it will cause this problem.

I am not sure if it is 100% apply to my case but my DC is a multi-home server because it is running as a file server too and this server has 3 network interfaces, one for LAN and 2 for iSCSI SAN.  The ip address for iSCSI SAN is different from LAN.

This server is the first DC in my domain and I have another 2 DCs in LAN as backup.   My current DNS is pointing to there

IP address : 192.168.1.55
Subnet mask : 255.255.255.0
Gateway : 192.168.1.254
DNS Server: 192.168.1.3, 192.168.2.1, 192.168.1.2

The ip 192.168.1.2 is my first DC.  

Based on this information, how can I improve the user's logon speed?
