Hi, I have a bunch of Windows Server 2008 R2 virtual machines (Hyper-V) - all installed from the same sysprepped image. One of these machines (my Exchange 2010 SP1 server) takes ages to log in... It just stays at 'Please wait for the user profile service'. In the event log, I see event 6005 (The winlogon notification subscriber <Profiles> is taking long time to handle the notification event (Logon).) and 6006 (The winlogon notification subscriber <Profiles> took 267 second(s) to handle the notification event (Logon).). The user I log on with is the same user I log in to every other server and I don't see any problems on any other server. Does anyone have an idea of what the problem might be? Thanks in advance! /Michael

did you try these steps? http://social.technet.microsoft.com/Forums/en/itprovistanetworking/thread/56310e15-32df-457a-bc38-4cc2fce0a5e5 http://blogs.technet.com/b/instan/archive/2010/07/06/the-case-of-the-mysterious-10-minute-logon-delay.aspx

I have tried NETSH INTERFACE TCP GLOBAL set autotuninglevel=disabled with no luck. I don't see any GP-related events in the log - only the 6005 and 6006. The problem can't be hardware related as it is a virtual machine. Other virtual machines don't have the problem.

If not GP, check DNS settings. http://serverfault.com/questions/96151/how-do-i-connect-a-2008-server-to-a-2003-server-active-directory In this post, someone solved the problem by disable IPv6 http://social.technet.microsoft.com/Forums/en-US/winserverGP/thread/ade979e7-b11e-4828-bfcc-bef42ee7015a/

DNS has been checked several times. I have also tested with other (internal) DNS servers - same issue :-(
