Problems Connecting Buffalo Terastation LS -WSX1.0TL/R1 to Network

Symptoms: The Device will be connected to the network, you will be able to ping the IP address assigned from DHCP to the device, but you will not be able to access the device using Web Interface and through network share too.

The issue resists even though you have installed the software’s provided in the CD ROM.

Resolution 1:

I found a very easy solution for the issue. As you know we have a small switch below the USB port, where it is mentioned as AUTO; ON; OFF as in the picture below (Marked)

By default the switch was on AUTO, so I was not able to access the shares and the web interface.

I changed it to ON, and the very few seconds I was able to access the shares and through web interface too.

Note: The Green Light blinks when the switch is at Auto, As soon as the Switch is changed to “ON” the Blue light starts to blink.

Resolution 2:

Reset the Device. (*IMP: Make sure you have the Data backup in other device or a computer)

–       Please switch the Device to OFF and wait until the lights are off.

–       Hold the function button for 10 seconds while it is still off.

–       While still holding the function button after 10 seconds please flip the switch to off.

–       Once the function light begins to blink release the function button and press it again for one second.

–       Wait until the power light is solid and this will restore your unit.

*This process will not delete any data and will only restore the admin password and set the IP address back to DHCP.

Also check for the Antivirus and the Firewall blocks, even they may come into picture.

Robocopy ERROR 5 (0x00000005) Changing File Attributes: Access is denied

This error may occur if the reported folder is not accessible by the Service account on which the Backup is configured.

I use the below Robocopy command to backup my files to a network drive:

Robocopy “Source Folder” “Target Folder” /e /r:3 /w:1 /sec /mir /z /b /np /log:c:\Backup.log

As in the above syntaxes used below are the description of them:

/e: Copies subdirectories.

/r: Retry Option.

/w: Wait time.

/sec: Copies the security permission as same as the source folder.

/mir: Mirrors the directory tree. (Same as /e or /purge)

/z: Copies files in Restart mode.

/b: Copies files in Backup Mode.

/np: The progress of the copying operation will not be displayed. (% progress of each file)

/log: Creates a log file in the root directory so that you can have the details of copy.

For the error 5, it may be due to multiple reasons, include the below syntaxes to troubleshoot the error:

  1. You need to use the /FFT flag to assume FAT file times (2 second granularity). Although the target folder is Ntfs/Fat, these file systems also implement file times with 2 second granularity.
  2. You need to turn off the attribute copying. Robocopy uses the /COPY:DAT by default, which means to copy data, attributes and timestamp. You should turn off attribute copying by explicit setting /COPY:DT

This syntax should resolve the issue with Error 5 of Robocopy.

The Final Robocopy command would look like this:

Robocopy “Source Folder” “target Folder” /e /r:3 /w:1 /sec /mir /z /b /np /COPY:DT /FFT /log:c:\Backup.log

You may also get an issue where some of the automatic files generated by windows will not backup; these files may include Thumbs.db or Desktop.ini

You can exclude these file by adding the /XF syntax in the command.

You may also exclude some of the unwanted folder to be backed up from the command, for that you need to use /XD

Example command to exclude the unwanted files or folders:

Robocopy “Source Folder” “target Folder” /e /r:3 /w:1 /sec /mir /z /b /np /COPY:DT /FFT /XF *.ini thumbs.db /XD .trash /log:c:\Backup.log

Hope you have an error-free Backup 🙂

DNS Forwarders

If a DNS Server does not have an entry in its database for the remote host specified in a client request, it can respond to the client with the address of a DNS Server more likely to have that information, or it can query the other DNS server itself. This process can take place recursively until either the client computer receives the IP address or the DNS server establishes that the queried name cannot be resolved. DNS Servers to which other DNS Servers forward requests are known as Forwarders.

The Windows 2008 DNS Server service extends the standard forwarder configuration by using conditional forwarders. A Conditional Forwarder is a DNS Server that forwards DNS Query according to the DNS domain name in the query. For example, you can configure a DNS server to forward all the queries that it receives for names ending with Ignitedsoul.com to the IP address of one or more specified DNS Servers. This feature is particularly useful on extranets, where several organizations and domains access the same private internetwork.

Here is a quick reference you can use to determine which tools to use to help locate and resolve problems with your AD network.

Q: User unable to access network resources?

Is the network functioning at all? Can you view a list of networked systems or even access resources on other computers? If not, you have network connectivity problems. The troubleshooting tools you should start with include: Event Viewer, Ping, IPCONFIG, NLTEST, NetDiag and Network Monitor.

Q: User unable to locate resources by name?

Is name resolution functioning? Can you resolve NetBIOS or domain names into IP addresses using Windows Explorer or PING? If not, you have name resolution service problems. The troubleshooting tools you should start with include: Event Viewer, NSLOOKUP, NBTSTAT and DNSCMD.

Q: User unable to log in and obtain its roaming profile?

If not, your DC is having problems. The troubleshooting tools you should start with include: Event Viewer, DCDiag, DSASTAT and NTDSUTIL.

Q: User is unable to authenticate?

Can any client log on locally or remotely? If not, your DC is not authenticating properly. The troubleshooting tools you should start with include: Event Viewer and NetSetup.

Q: User unable to access resources as expected?

Can you access objects that you should be granted access to, and are you restricted from objects that you should not have access to? If not, then either the ACLs or DC is not functioning properly. The troubleshooting tools you should start with include: Event Viewer, DSACLS, NETDOM and SDCHECK.
