Linux log error – Could not receive trustdoms : xxx Time(s)

When using Samba with Linux, Red Hat Enterprise Linux attempts to connect to a Windows server that acts as the domain controller. This is called a trustdom; as Linux is attempting to build a trust relationship with a Windows Domain Controller. You will see the following message in your log:

——————— samba Begin ————————

**Unmatched Entries**

nsswitch/winbindd_util.c:trustdom_recv(243) Could not receive trustdoms : 288 Time(s)

———————- samba End ————————-

To stop this error message, you need to stop the winbind service. To do this, run the following commands:

chkconfig winbind off
service winbind stop

This will ensure that upon reboot, the service does not start. And the second command ensures that the service is stopped immediately.

Check your log tomorrow to ensure that you are no longer receiving this message.

Windows service failure while running in a QEMU virtual instance

If you are running Windows under QEMU and see Event ID 7000’s like these below–

If you get this Description:

“The Parallel port driver service failed to start due to the following error:
The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.”

Then you have the ParPort service not starting. This happens if you upgrade your W2K3, W2K, or NT server from hardware (motherboard) that HAD a Parallel Port, but are now on a new motherboard that has no Parallel Port.

The fix is simple:
1. Open Regedit and go to–
HKLM\System|CurrentControlSet\Services\Parport
2. Edit the Start key and change the value to 4. Changing the value to 4 will “disable” the service.
3. Reboot the server

You should no longer get that annoying popup dialog when Windows starts.

Windows Vista how to boot up without network

For security, sometimes you do not want your computer to automatically start up allowing network connections. In Windows Vista there is a way to ensure that when your machine reboots, network connections will not be enabled. They will only be enabled once you log in the first time.

To do this, go to Control Panel -> Administrative Tools -> Services.

Then change the Network Connections service to Manual.

This will prevent Windows Vista from establishing or allowing any network connections until the first time you log in.
