Slow Login Times when using My Documents Redirection

I used My Documents folder redirection in a Windows 2000 domain 5 years ago and never had any slow login errors or issues.  When I tried to implement the same type of policy on Windows XP SP2, I started seeing a minimum 20 second login time.  Especially when you refreshed the group policy.

It looks like Microsoft has identified a problem with Ntlanman.dll and created a hotfix.  It looks like they have rolled the update into Windows 2003 SP2 and may be slated to include the update in XP SP3.

To recreate the problem:
  1. Apply the group policy (gpupdate /force) and logout
  2. Login as user with My Documents redirected
  3. Log out and in again to see no login time penalty
  4. Force the application of group policy (gpupdate /force) and logout
  1. or wait a day or two for the policy to refresh on its own
  • Login as the same user and see a minimum 20-second login time penalty when you see the "Apply personal settings"

  • You may experience a 20-second delay when you try to access a redirected folder by logging on to a Windows Server 2003 Service Pack 1-based computer or to a Windows XP Service Pack 2-based computer
