Network login takes lot of time

This is way too vague a problem description to be able to even make a suggestion.

What kind of Laptop?
What operating system?
Any problems getting to the login screen?
Are you able to log in, but not load the profile; or not log in at all?
Is this after starting a machine that was off, after logging off and back on, or when trying to switch users?
Are you logging on with a local account or a domain/network account?
How many profiles are on the PC?
How much space is available on the HDD?
Does it load a temporary profile, or just error-out?

If you are getting error 571 from Nebraska Book Company's WinPrism inventory control system, File --> System Settings --> set the Receipt Type to 8-1/2 X 11. It seems irrelevant but it works.

Another possible resolution to the problem is to remove the Windows (XP, 7, 8, 10) profile of the offending user:

0. Login as the offending user and backup anything they want to keep, like browser bookmarks/favorite or documents on the desktop.
1. Log into Windows as a local administrator.
2. Control Panel --> User Accounts --> select the offending user --> Remove.
3. Restart.
4. Log into Windows as a local administrator.
5. Delete C:\Users\offending_user
6. The following is necessary to avoid a "temporary profile" error: Regedit.exe HKEY_LOCAL_MACHINE --> Software --> Microsoft --> Windows NT --> Current Version --> ProfileList --> select each entry until you find the one with a ProfileImagePath of C:\Users\offending_user and delete it.
7. Control Panel --> User Accounts --> add the user.
8. Login as the offending user, add the printer, and now it should work.

When you removed the computer form the domain, you can no longer login as a domain user. You need to know the login credentials of a local user of that machine. (Administrator, is almost always a username, ans you would need to know the password of that user. Thanks!

The question is:

What causes a user profile not to be loaded in Windows domain based network?

the answer is:
there are probably 3 broad reasons for this,
1. the user corrupted their profile somehow, such as shutting down without logging off (hard power off)
2. the connection to the domain was lost ungracefully, and offline information was not copied entirely, causing a mismatch of some encrypted profile data, (effectingly corrupting again) and preventing the logon.
3. an unknown event took place between the last time the user sucessfully logged on, and this time where the profile is now not loading. this could be hardware related (faulty Hard disk), RAM parity errors( bad memory), a change to the user profile SID details on the domain controller or other domain change.

Usually the cause is not so much a problem, unless it consistantly reoccurs.

Fixing it however, in XP is fairly easy.
with an account with domain admin rights, just navigate to the UNC path "\\computername\c$\documents and settings" - note the name of the folder/user affected, and just .old their profile folder.
example, username is Philip. - you see in their c:\documents and settings\ folder the folder called Philip, rename it to philip.old or something else.

You have to ensure this is done while the user is logged off, as files in this folder will be in use otherwise. potentially useful to reboot the computer before navigating to the profile folder.

The only way i found to stop it was to copy the profiles to a new spot and then delete the user and then remake the user and log in as the user and then log out and then copy the setting back to the user replacing the files.

If your not the administrator of the domain, contact the domain administrator, only he can give you the
relavent permissions.

Hiii

Ok after assiging a workgroup to the domain, plz make sure u gpupdate ur system , certain times it does take 60mins for changes to take effect.

Regards.

are you loging in onto the network? if so you'll need the network user account name and logon

if you know the logon name and password make sure your logging in to the computer user profile not the networked one.

typically the user name is Administrator. 2 accounts are created admin and guest, though most the time Guest is not activated.

if your really outa luck Try a program called Ophcrack :]
either use it as a bootup disk or run it google it sourceforge!

When you "logon" to your local network, your computer is configured to fetch your "desktop" (My Documents and wallpaper and everything else) from a "server" computer on your network.

Was your "logon" to the local "domain-server" a successful login?
Does your local Network Administrator indicate that the "domain-server" is functioning properly?
Does that server's log-file show any error-messages, such as "not allowed to login between 10 PM and 6 AM" (a "security" setting on the server).

Since your "desktop" could not be loaded from the domain-server,
your computer has used a "local" copy of your "desktop",
and it is warning you that any changes will *NOT* be "merged" back to your "network" profile.

Have you contacted you local Network Administrator? What did she say?
