Our environment has a windows server 2008 as DC and 250 users. All users are using roaming profiles and that works great. We have 10 mobile users and when they are onsite there are no issues. All machines run Windows XP Pro, and if 32 bit SP3 and if 64bit SP2. But when they leave and log-on to their laptops locally outside of the office the log-on is rather long in some cases taking as long as 3 minutes.
Users are also receiving this error, Windows cannot locate the server copy of your roaming profile and is attempting to log you on with your local profile. Changes to the profile will not be copied to the server when you logoff. Possible causes of this error include network problems or insufficient security rights. If this problem persists, contact your network administrator.
DETAIL - The network location cannot be reached. For information about network troubleshooting, see Windows Help.
Which would make sense seeing as how they are not connected to the DC where their profiles are.
So, how can I speed up logins and suppress this message?
