Command Line to Get Dell Service Tag or HP System Serial Number


Get Dell Service Tag of a Server or Desktop Computer System using just a Command Line

Get a Dell service tag or HP serial number of a server or desktop computer system by using only a command line. Third party utilities or other OEM tools like Dell BMC are not required. Dell Open Manage tools or agents don't have to be installed. On an HP server, Server Manager or HP management agents don't have to be installed. On a Windows or Linux system (Linux command line shown further down in this post), the Dell service tag or board serial number of an HP server or desktop computer system can be displayed by using native Microsoft Widows Management commands. To get and display the Dell service tag of a system with windows installed (Windows XP or higher) simply open a command prompt window, also known as a command window, and enter the following command. 

C:\> wmic bios get serialnumber

Hit enter and on the next line will be displayed the Dell service tag or the HP serial number. Obtaining this information will help looking up the system, server or desktop computer, on the appropriate web-site, Dell or HP, to obtain drivers or other related software and warranty information. 

Alternatively, the following command will provide the same information: 

 C:\> wmic systemenclosure get serialnumber

The same Command line can be used to get the serial number or service tag of a white-box computer system. 

Getting the serial number or tag of a whitebox system is done the same way. Unfortunately, the results may not display the information you need because the manufacture must have populated the field that is queried with the Windows Management command. IN many cases, what will be displayed in place of the serial number or is "To Be Filled by O.E.M." .  

Using only a command line or shell to obtain the system serial number or Dell service tag on Linux

You may have the need to obtain a service tag or serial number of a Linux based computer system server or desktop. The idea and principles are the same With a simple command line display the serial number or service tag. Dell, HP, or IBM tools are not required. The command to get and display the serial number or service tag is different from windows of course but the results are similar. The following command line from a shell works on Linux and Cent OS, other distribution could and will work too but I only tested with these two distributions of Linux.

On Linux Execute the following command from a command shell to get Dell Service Tag

      # dmidecode | grep -i serial      
      # dmidecode -t 1

 DMIDECODE may have to be installed first before the command will be successful. Again, no HP or dell or IBM tools are required.  
# yum -y install dmidecode

Automatic Detection of Intranet Security Not Working.

Error : Security Warning -  we can't verify who created this file.

Change the following setting on the local machine using local policy or use a GPO to configure this setting for an OU or domain.  What this setting does, and it worked perfectly, was to apply Intranet Security policy for any computer that is on the domain.

The automatic detection has an issue with shortcuts or urls that use the FQDN even if it the local domain. Setting this policy make that Autodetection work. This was a domain with a 2003 domain controller and a windows serer 2008 R2 domain controller. The GPO setting was configured using gpedit on the 2008 server. No additiona administrative templates or kits had to be added. Thi s was with the default admx files found on 2008 R2.

To set the policy setting:
Open gpedit on the Windows 2008 server > User configuration > Administrative templates > Windows components > Internet explorer > Internet control Panel > Security Page
   Enable "Turn on automatic detection of intranet"

Dell Wyse Xenith Review for Citrix Fast Installation Zero Client

Zero client review | Wyse Xenith Zero clients for Citrix HDX

  • Superb boot time
  • Awesome speed
  • Detailed confirability
  • Easily manageable 
  • All settings easily accessible 

Wyse Xenith Zero clients for Citrix Installation and Speed Review

Installed fifteen Wyse Xenith Zero clients for Citrix HDX. That is not a large number of clients to install but it was the first of their kind that I was able to get my hands on. These clients were the best I have ever used.
I thought I admired the Windows Embedded client from Dell Wyse as those had installed 25 for another client prior to these Zero clients.

The embedded clients ere impressive. I thought those would be the best I would see but after installing the Wyse Xenith Zero clients for Citrix HDX , they were even easier and quicker to deploy. They boot up in seconds, about 5 to 8 , average (it was just lightning fast, at first I thought I was not booting them at all - you blink or look away for a second or two, you'll miss it)
Dell Wyse Xenith Zero client. 

The embedded clients have a longer boot time and have a desktop of an embedded windows operating system to take into consideration whereas the zero clients have only the Dell Wyse Zero Engine. The boot time for the zero client was about 5 seconds to a login form/page. That was a complete power cycle. Login is quick, access to admin features was very fast and easy too.

Dell Wyse Xenith Zero client Speed 

Admin features can be made to be displayed on the left side of the screen on mouse-over if required. In this case it was made to remain hidden. Accessing admin features was very fast too with most changes requiring a reboot, that was no problem as the reboot was so fast.

Access Wyse Xenith Admin Settings, How to Access admin mode on Dell Wyse Zero client

To access administrative settings just hit control + alt + delete. You'll be given options in a small window that is displayed. Choose display admin option button and restart. Once you reboot, which is very fast as mentioned, click on admin, then you have access to all the settings - and there are a lot of settings to customize the the thin client to you needs and specifications. Optionally, while restarting/rebooting, hold the shift key down on the keyboard. You will notice that the admin button stays after reboots and power cycles. To get rid of the admin button on the zero client, just hit control + alt + delete and select the option not to display the admin button.

The Dell Wyse Xenith Zero client has many Settings to fit any Environment

Wireless settings can be configured as well as standard wired network settings. The default domain of the client can be added. The default username and password if desired can be configured. Also so many display and and other settings such as the zero clients name on the network, resolution and even the settings by which to find and connect to a management server or servers. All settings can be done manually at the client per client of can be managed by Dell Wyse client management software.

IE9 Meet Your New Browser Welcome Page Tab Opens When IE9 Starts

IE9 Meet Your New Browser Welcome Page Tab Opens When IE9 Starts

This is a very interesting post. It involved IE9 and the Meet your new browser welcome page. It has been written with a solution by the author for windows 2008 R2 server but the same solution can be applied to windows 7.

Prevent Internet explorer Welcome Tab from Opening

IE9, although it looks very similar to IE8, is a different browser in many respects and in particular in regards to security. One of the differences hat can catch a terminal server admin (RDS windows 2008) a surprise is that cookies are disabled by default with IE9. Admins will now, one way to circumvent this problem would be to setup the default user profile before the suers begin logging in for the first time. One hey login, their local or roaming profile is created and used after that. Once the user profiles have been created, the solution for solving the cookie problem can be solved using a logon script.

Internet Explorer 8 and Internet Explorer 9 Welcome Page Tab

The meet your new browser welcome tab can also be very annoying and for less savvy computers users, cause them to call in for tech support.
One of the ways to solve the meet your new browser welcome page and also make the IE( setup question asking the user to select express setting or customer settings is to use local group policy editor on the server.

HP NC373i: The network link is down


This error would appear in the system log of the server almost everyday in the morning - HP NC373i: The network link is down . Never during the day such as late afternoon or evening. The error would occur early in the am hours juts before and at times when employees juts start reporting to work. Event id4, source l2nd.
The driver version was not updated yet. The possible solution is checking and disabling power save mode for the NIC. The server was running windows 2003 server standard edition on an HP Proliant series server hardware platform. The next step will be to update the driver version. There have been TCP offload problems with some drivers. The version installed on this server was fairy new but an update was available.
