Public DNS Servers

Public DNS servers are a great resource when you are somewhere that does not have a reliable DNS server.  We were recently at a trade show and needed DNS, but had no idea what we might see when we got there.  So I just set it up with a public DNS.

There are lots of Public DNS servers out there including the Public DNS Server List list , but I just decided to go with Google’s DNS Servers.

The Google Public DNS IP addresses (IPv4) are as follows:


The Google Public DNS IPv6 addresses are as follows:

  • 2001:4860:4860::8888
  • 2001:4860:4860::8844

Google also has an excellent document on Using Google Public DNS for those who need extra help setting it up.

The Public DNS Servers are a great resource for the Internet Community and I thank them for making them freely available.

All Windows File Shares Broken

Problem: Can not access ANY file shares in the network. Even machine to machine.

Found some NS log errors in event viewer

Computer not able to logon to the domain:

This computer was not able to set up a secure session with a domain controller in domain [DOMAIN] due to the following:
There are currently no logon servers available to service the logon request.
This may lead to authentication problems. Make sure that this computer is connected to the network. If the problem persists, please contact your domain administrator.

Group Policy Failed:

The processing of Group Policy failed. Windows could not resolve the user name. This could be caused by one of more of the following:
a) Name Resolution failure on the current domain controller.
b) Active Directory Replication Latency (an account created on another domain controller has not replicated to the current domain controller).

NtpClient unable to get the time for the domain:

NtpClient was unable to set a domain peer to use as a time source because of discovery error. NtpClient will try again in 3473457 minutes and double the reattempt interval thereafter. The error was: The entry is not found. (0x800706E1)

Checked the domain controller (WS2003) and it has a mouse pointer and a gray screen.

Tried to reboot the server.  Ctrl+Alt+Del – nothing, Hard reboot – success.

System rebooted and now able to connect to file shares.  Started looking at logs and got a message “Automatic Updates – Updating your computer is almost complete.  Your computer needs to be restarted for the updates to take effect.”

On the domain controller I found that it had started doing a windows update the previous night.  And also this message from the previous night.

This computer could not authenticate with \\[Server], a Windows domain controller for domain [Domain], and therefore this computer might deny logon requests. This inability to authenticate might be caused by another computer on the same network using the same name or the password for this computer account is not recognized. If this message appears again, contact your system administrator.

And this one too:

This computer is configured to be the primary domain controller of its domain. However, the computer EXTSERVER is currently claiming to be the primary domain controller of the domain.


The browser has forced an election on network \Device\NetBT_Tcpip_{DC2707B3-885D-4F87-9FB1-A844145E5013} because the Domain Controller (or Server) has changed its role.

Synology Diskstation:

The Synology Server is still not authenticating correctly.  Rebooted cleared that up, perhaps getting a new, good, connection to the windows authentication server.

Canon MP980 Printer Head Cleaning

I’ve been having some problems with my Canon MP980.  First the black was sketchy and wouldn’t pass the grid tests.  After lots of head cleanings, it finally was working.  Then about a month later, the Cyan was faded (which came back) and the Black would print for a page and then get lighter and lighter, eventually not printing at all.  So after a little internet research I decided to give cleaning the printer heads a go.

The best article I found was an answer to My printer does not print light magenta. (Canon MP220 – CL-38).  It references another extended discussion on whirlpoll, Print Head Cleaning Canon MP980 which has even more information.

Step 1: Remove the Ink Cartridges

Open the printer and remove the ink cartridges.  Place them in a zip lock bag so they don’t dry out.

Step 2: Remove the Print Head.

Lift the Gray Lever up, grab the print head firmly and pull out under the gray lever.

The print head is now removed.

Step 3: Clean the print head with warm water

Run warm water gently  through the ink jet ports.  Ink will come pouring out the bottom.  Turn to spray the bottom and sides as well.  Do a final rinse with polarized water to get rid of any minerals.

Step 4: Wait for the Print Head to Dry Thoroughly

Set everything aside until the print head is thoroughly dry to prevent any damage to the electronics.  This will take a while to get everything dry.

Step 5: Reassembly

Put the print head back in to the printer, insert the cartridges and test the printer.
