Netsh interface tcp set global autotuninglevel=disabled I disabled the offload chimney on the workstation but there was no improvement.Ī co-worker of mine eventually found a command to disable auto tuning, and on a whim we tried this on the workstations by running the following command on in the command prompt logged in as the domain admin:

I created another new test user.I moved the test user into this OU and ran a gpupdate /force.Įven with the new OU, New GPO created on a Windows 7 PC and a brand new test user the problem still persisted.Įventually I remembered that we experienced a problem very similar to this with this client’s Mac 10.5 clients attempting to attach to windows SMB hosts, and the resolution was to disable the TCP/IP Offload chimney on the server. I then set about re-creating the document redirection policy on one of the windows 7 workstations, and creating a new OU for testing.

I also created a Central Store for Group Policy Administrative Templates on the Windows 2003 domain by following the procedure on KB929841. I downloaded the RSAT tools for windows 7, installed them, and installed Group Policy Management console. This was a big finding something in our document redirection group policy was causing the slowness, 3 minutes with IPv6 disabled and 10 minutes if IPv6 was enabled. I also created a new user in an OU that does not have any policies applied and verified that this user DOES NOT experience the slow login times.įrom here I started applying policies one a time to this new user and logging into the computers, it was at the Desktop and My Document redirection policy that the slowness re-appeared for all users, including the new one that previously wasn’t experiencing the problem. Disabling IPv6 on the client computers, this improved the time from about 10 minutes to about 3 minutes, but still it was taking too long to log in.

Moving the new computers into their own OU with NO group policies applied, and block inheritance enabled.

I stated doing some research and I came across a variety of things to “try” of which these were: Took 545 second ( s ) to handle the notification event ( Logon ).
