You cannot log on locally or remotely to your Microsoft Windows Server 2003-based computer


Symptoms


You cannot log on locally or remotely to your Microsoft Windows Server 2003-based computer. When this problem occurs, you cannot use the following methods to log on:
  • Log on locally.
  • Use a Windows domain logon to log on remotely.
  • Use the Remote Desktop Protocol (RDP) to log on remotely.
For example, after you enter your user name and password locally on your Windows Server 2003-based computer, your computer may appear to stop responding. However, the Windows Server 2003-based computer is still functioning, and users may still access file shares. Additionally, the Windows Server 2003-based computer can still be managed remotely by using the Computer Management tool.



When you restart the Windows Server 2003-based computer, you can log on successfully. However, after your Windows Server 2003-based computer runs for several hours, the problem occurs again.

Cause


This problem occurs when the network redirector encounters an error while it tries to create a server message block (SMB) connection to a remote computer. Subsequently, this error prevents the SMB component on the Windows Server 2003-based computer from creating SMB connections. The logon process may stop responding because the Windows Server 2003-based computer is repeatedly trying to open an SMB connection to a domain controller.
