I have client machine that cannot access any network resources. When the client logs in it goes to the desktop and does not fail when inputting network password. Once profile has finished loading outlook askes for network password and so does that mapped drives. When the user inputs his credentials he immediately gets a message stating that the account is locked out. The setting for account lock out are set to 5 failed attempts, but he only tries once and gets locked out. I changed the network card and that is working fine user can access internet which is LAN based. I deleted his profile and recreated thinking that it was corrupted and that has made no difference. His profile is set to roaming , but saving to the server fails, but he loses no settings. This is very perplexing as it seems that his credential are failing even though i reset the password at the server level and was ok. Help

does this happen to all the mapped network drives. and is it only problem with one server and a client or throughout the domain.

what about SMB signing , did you check that. is it only for one particular user ?
you also mentioned that the users roaming profile does not save to the server did you enable userenv and check why its not saving the profile

try this : http://support.microsoft.com/kb/221833
and also are there any errors in eventvwr ?

so it sounds like he is logging on with cached credentials intially.....are there any services running under his name that may have an old password in them? drive mapping scripts with wrong passwords etc...

Kprad this is only happening with one user, SMB signing is not enabled. I have not enabled userenv and there are no errors in the event viewer.

Jay_jay70, I see where you are going with this. I will have to check his system out as he is running a huge amount of software. As for script files I control those with script Logic which runs at startup, using an account with admin priviledges that the user does not have.

so scripts are most probably clean, maybe something else left in an app somewhere

I have some more information, when the user logged in this morning this was showing in his event viewer:

Event Source: is Userenv

Windows cannot bint to anyone.local domain. (invalid credentials). Group Policy processing aborted.

I created his credentials in AD, could it be a corrupt account.

I have found the solution to this problem. As per Event Id.net I accessed the user computer wnet to control panel -->User Accounts-->Advanced Tab-->Manage passwords. I removed the user from the list and had him reboot and now everything is okay, Profile is being saved and credentials are being accepted.
