Windows 7 Slow logon to domain

Hello,

I have a very strange issue that I cannot seem to determine the root cause.

SBS 2011 Server with all updates and fully patched.

All clients are laptops with windows 7 pro and have DHCP addresses from the SBS server and DNS pointing to the SBS server.

The network is wired and wireless with WPA encryption.

Randomly the clients cannot logon.  When they enter their credentials they get stuck at the spinning circle with "Welcome" on the screen.

I have looked in the event log and do not show any errors such as group policy that they are getting hung at.  

So far I have found three work-arounds.

1.  Disable wireless adapter
2. Remove and re-add workstation to domain for temporary fix
3. Delete one of the DNS records in the SBS server for that workstation.  There are two records because each workstation has a wireless adapter and Ethernet adapter with different ip's.

Any Ideas?

First, enable Verbose mode for your domain (Computer Config\Admin Templates\System).

This will tell you if a specific client side extension is holding up logon.

Next, check out: http://msdn.microsoft.com/en-us/performance/cc709422.aspx

This tool allows you to trace logons and will identify the exact process preventing the logon.

Should Verbose mode be enabled for all systems domain wide?

Yes. It changes the default generic logon/startup messages into the actual process being ran "Applying Group Policy Printers".

In our domain, we run it on 5,550 computers and all of our servers. So much more helpful!
