I'm having an issue with my domain controller. The office is running windows server 2003 AD DC with DNS, DHCP and file sharing with about 30 workstations connected to it. I got called in because the office was complaining about problems losing network shares randomly. Sometimes, they will reboot and it will be ok, other times, it continues to act up. I got here and checked it out and found several computers that when I tried to access network drives, got the error: Login Failure: the target account name is incorrect. After rebooting the computers, most of them are working, but not all of them. I even rebooted the server. Still nothing. I've been doing research on this forum and ran many diagnosis tools but i still can't find the problem.
On the computer I"m having most trouble with, I removed it from the domain and rejoined the domain but it still doesn't work. Then i tried to change the computer name and i got the same error: (login failure...). So then I removed the computer from the domain and changed the computer name no problem. But when i tried to rejoin the domain, I was unable to join and got the same error (login failure...). I've tried removing the computer from the list of active directory users and computers and it deleted just fine. But when i tried to add the computer back to the list I get this error: "MMC has detected an error in a snapin. It is recommended that you shut down and restart MMC". I'm to the point where i need to ask for help. Please help!!
