Server 2008 R2 Slow startup while applying computer settings

Server 2008 R2 Slow startup while applying computer settings

I’ve had some trouble with slow logon on Windows Server 2008 R2. The “Applying Computer Settings”-part takes about two minutes!

The eventlog shows two records about this issue:

The winlogon notification subscriber <GPClient> is taking long time to handle the notification event (CreateSession).



The winlogon notification subscriber <GPClient> took xxx seconds to handle the notification event (CreateSession).


I stumbled upon some possible solutions. The first was updating the NIC driver. As I’m using the wireless network card, I’m only updating this one.

Updating NIC driver

Old driver:


New driver:


Drivers are updated but the logon time wasn’t reduced by a single second. Crying face

Disable Computer GPO’s

Second try was moving the computer object to a unmanaged OU (without policies applied), run gpupdate /force and rebooted some times .. but the problem still exists.


Third try: adding GpNetworkStartTimeoutPolicyValue with value 1 to the registry:


Maybe it’s a service or application on the computer itself .. ? I disabled some 3rd party (non Microsoft) services, but the problem remains.

Disable IPv6?

–> no luck

Disable CardReader?

–> no effect

Disable Autotuning?

netsh int tcp set global autotuninglevel=disabled


Didn’t solved it either, so I enabled Autotuning again:

netsh int tcp set global autotuninglevel=normal

KB2525332: You encounter a long logon time after you enable the "Do not automatically make redirected folders available offline" Group Policy setting in Windows 7 or in Windows Server 2008 R2

–> This hotfix fixes the slow logon issue for me! (I’m using redirected folders!)

    Hi Ben
    Sorry to hijack this post, but I wanted to ask you something about MDT 2010, sadly i can’t see a personal message system here.
