Restart the DC

I'll have to wait till the end of the day to restart.. any other suggestion or what should I do after restarting the DC means the "server"?

You can't print or access any network device because you are logged in with local client cached credentials.

It sounds like your account got disabled.

If your account is disabled like kkohl suggested, you should be able to log in to another workstation just fine.  If that still does not resolve your issue remove the computer from the domain and then rejoin it to the domain.  My guess would be the windows account in Active Directory is corrupt.

Yeah I shouldn't have jumped to rebooting the DC, if it is just one account that is bad or that machine start the trouble shooting there.  If all machines can't print, etc then restart the DC.

Can you tell me what  is the result of:

ipconfig  /all

OnsiteComputerMedicsCommented:
change the machine to a workgroup and then rename and add it back to the domain.

kkohlCommented:
Check your account logon.

Go to a users machine you know is up and working, network share access, printer access, internet, etc...

Log on that machine.

If you have the same error (cannot find domain controller or no permissions) the issue is your account settings...
Find your network admin and find out what happened to your account.

If you can log on successfully and access your network shares and printers from another machine the problem is isolated to how your machine is handling security.

Lets go from here :-)

I tried to logon from another PC .its same problem

kkohlCommented:
It is your account.

It is either disabled or, as inlinemike suggested, corrupt.

Get your network admin and look in Active Directory to see the status of your account.
If its disabled, re-enable it and reset the password if necessary.

Digital_Output, assuming you have security auditing turned on for object access failure, if so what is the event log telling you for all accesses to the printer?  That's a starting point.  Check the event logs on both the affected workstations AND the domain controller.  Try to understand the reason that access has been denied?

Also, think simple.  Check everything.  All necessary network settings, cables, etc . . .
Make sure all the necessary services on the domain controller(s) are operational, etc . . .

Second thing, at the time of failure, was the clock on the workstation more than 20 minutes different from the domain controller?  HHas anyone tampered with the computer's account on the DC, and maybe even erased the DC?  Anyone tampered with the clocks?  Kerbos authentication/security is very dependent on the clocks between workstations and servers to be as close to accurate as possible.  I think a maximum 30 minute difference is allowed between computers before Kerbos authentication fails.

Something you could try and do is remove the problem computer from the domain, make sure the machine/computer account is removed from the domain controller(s) (Give time for replication between DCs if toy have multiple DCs) and then re-introduce the problem computer as a member of the domain.  That's if you don't feel like re-synchronising machine passwords.

To see a command to reset machine passwords, at the domain controller start a command prompt window (DOS prompt [aka. `CMD.EXE`]) and issue the command:
NETDOM RESET

That will just show the syntax of the command.

Also see:
 Description of Netdom.exe Syntax and Versions
 http://support.microsoft.com/default.aspx?scid=kb;en-us;329721

This is all under the assumption that the machine password used between workstation and domain controller is wrong.

Now, you do seem to indicate that it's happening on all workstations?  First bit of advise to check the event logs on ALL affected computers stands.  Advise to check the clocks also stands.  If the clocks are wrong, make sure the clocks are right and try resetting the machine password for one of the affected workstations.  If that works, try another, if that works, then reset the machine password for all domain connected workstations.

Out of curiosity, what was causing the problem and what action did you take to cure it?
