I join my windows 7 Ultimate PC to a windows 2000 server domain controlerI try to add my user like windows XP, Vista but got: "The trust relationship between this workstation and the primary domain failed" errorI follow this answerhttp://social.technet.microsoft.com/Forums/en-US/w7itpronetworking/thread/7d0bb953-3514-4475-8f00-5f624f5f6b00but... everytime I log into my domain user account I lost all my preferences (is like I log for the 1st time)

Do you receive any errors at all while logging on as the domain user? Also can you check under C:\users\ whether a new profile is created each time or if it is simply not saving the one already created?

no errorsI configure my outlook account and set more preferences, copy files to my documents foldersI restart then again I log on and tell me is preparing my desktopand all the configurations I do are goneI check the c:\users and the folder of the user is cleanmy user is domain admin btw

OK - I think I have seen something similar before. Can you try the following?1. Login with the domain account2. set a few things up3. restart the PC4. login with a local admin account5. check c:\users for the domain account profile folder and delete if there6. go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList 7. delete the entire folder for the domain accountrestart, log in as the domain user and test again.Hope this will lead to a solution....

I am having the exact same issue. Everytime that i log on it gives me a clean profile. I tried KACENKA's idea to no avail. I am logging in as a domain admin in a win 2000 domain. running a 1 day old Dell Vostro 3500 i5-M560 with 6GB ram Anyone have any clues on a fix for this??

OK... here is a little more information. as it turns out the profile actually is getting removed when i log off. I logged in... added a file to the desktop just to make some sort of a profile change... then did a logoff and loged in as a local user and then looked in the c:\users directory and the profile name was not even there anymore. as a sidenote i had a non domanin administrator log in and rebooted and logged back on and it works just fine!! Really strange and frustrating!!
