The problem is from the user enters his/her password and press ENTER and to

It's not caused by a slow loginscript since it works fine on the rest of the
computers.

Hi,

You need to ensure that you are troubleshooting a slow logon, rather than a
slow startup. Ensure a clean boot of a client an wait for all services to
finish stating up and the machine to be idle. Then start timing the logon
process. If logons are slow becuase of GPO you would expect them to be slow
at all times. Luckily, this is pretty easy to rule out. Move the user and
computer accounts to different OUs that avoid all policies and re-test the
logon process.

You may also need to run some performance monitoring on your DCs while
clients login to see if they are resource contrained.

Typically slow logons that really are slow can be caused by:

1: Resource constrained DC/Server
2: Bad/Slow logon scripts
3: Slow sysvol performance (say over a slow link)

I once had a situation where some DCs for remote sites had been built in the
main location and left on for a few weeks then shipped interstate. Some
client had faulty sysvol referrals with a 120 day lifetime instead of 15
minutes, so all the traffic was going over a slow link. It sounds to me like
your network is a bit smaller than this.

Cheers,
Jeremy.

Hey

I am having problems with some client computers that are very slow to login
to our AD. The DNS settings are working fine because it's not all the
computers that have the problem. All the computers have two DNS servers that
are both internal.

The only things I can come up with is either problems with the local profile
or our GPOs are slowing up the login process (We have 4 GPOs).

Do the users in question have a roaming profile? Try removing the
profile path from within AD users and computers and see if that
improves login speeds.
