DHCP Statistics

DHCP statistics is a basic option that is available to DHCP admins to take a rough look at the stats of DHCP role working.  Following is a sample look from a test lab environment:


It gives the info about the start time, up time, total discovers and offers (we can take it as unique mac addresses or PCs in simple), number of requests and acknowledges from start time, declines, releases, number of scopes and total possible address and how many are in use and how many are free.

One can see this window by going to the Display Statistics option on scope.

Many or all Browsers Crash

In the race to win the software market, some vendors are going too fast that they are forgetting to do some quality checks on there products, this article is speaking of no small firm, it is about the Adobe and the product is the most used one “Flash Player”.

The issue is that, some sites, my case, youtube requested an upgrade of flash player from my current version 10 to new one 11 as a requirement to view videos and I have upgraded, after upgrading when ever a video is being played on IE, Firefox, chrome, in all three browsers get hang due to flash player alone only.  After through browsing figured it out that the new version is not working properly when Hardware Acceleration is enabled and the software by default is configured to use it, it would had at least been if it is disabled, also, on the adobe official forums the support is very very little from them, the solution is taken from a remote forum.

The solution is to disable the Hardware Acceleration from setting, settings option can be fond on right click menu on any flash player event like video on youtube, just right click on video to get the settings option:

Then Uncheck the hardware acceleration:

Hope it helps.

Remote System Performance Monitoring

Following is the procedure for collecting or monitoring the reports from a remote system, in the below example following is the setup:

Serv1 – DC and DNS, domain is

Serv2 – DHCP and this is the PC where we are running Performance and Reliability Monitoring Console/Software.

Following is the process:

Firstly:  Add the domain user or Administrator, whom ever is given right to monitor performance to the Reports to the system where you want to view report, in this case it is Serv2 process is a below:

Administrative Tools>Computer Management>


In Computer Management>Local Users & Groups>Groups> Open for Performance Monitor Users


Click on Add for adding the respective user


Provide the username and perform Check User Button to make sure the name resolves and then click on ok.


Then you would see the complete box as follows:

console after adding

We completed providing the required rights for using the performance and reliability management rights.  Now a data collector must be created for collecting data.  Steps are as follows:

Open Reliability and Performance Monitor from Administrative Tools

performance and re

Under Data Collector Sets in Console Tree, right click on User Defined and for New Data Collector Set


Provide a Name and Select Manually or Template based on requirement, I prefer manually for most customized


Click on Add


Then click on browse to add a remote system name, type in the name in the box and click on check name to make sure the name resolves, then click on ok.


In the below list, select the required counter, for instance I select the entire DNS, then click Add to add then


Then change the interval to 1 sec, treat this as to when the report collects data from the remote pc.


Then you you can see that the data collector set is added.


If we start the report right always, we get the following error when viewing the data “At east one of the input binary log files contain fewer than two data samples.” meaning no data is collected.


To start collecting data, a small change is required.  For a remote PC to access another PC, there must be some authorization required, hence we need to provide user name and pw, by default it runs with SYSTEM rights. 

To do this, right click on the report and go to properties


Then select change in Run as section as shown below


Type in the user name, in my case it is administrator


Click ok and close that section.  Hence now you can start the report by right clicking it and click start.

Indian IT Future

Is India's IT future promising?

If it is to me, I would surely say not, why?

The rate which the new technologies are growing and is humongous, mainly the shift towards the cloud computing is one major reason to mention.

We we go down the streets in the country we can see all sort of banner ads etc. that display "We teach C, DS, .net" etc., where we should be taught about com integrations and WCF,WPF, WFF technologies etc.

Indian Education as it is praised is only something like a Humans Defense Mechanism to keep itself cool.  For example, attending the IIHT institutes which has promising brand name in IT infra education is still teaching the server 2008 with incompetent faculty India wide, where they must teach with excellent staff for new technologies like System Center Suite, Windows Azure etc.

I am not criticizing the nation, but just pointing the issues, I am too an INDIAN and proud of my Nation.

DHCP Administrator only for Domain :(

For testing the DHCP, I tried to take a n approach to use a none Domain Admin account, I created a user by name “” where is the forest/domain.  Serv1 is the DC and Serv2 is the DHCP Server and is under the same domain “”.

dhcppavan is the member of Domain DHCP administrators and Domain Users groups as shown below:

Member of

After testing I found that being a DHCP Administrator account I cannot create/modify/delete/authorize/unauthorized any DHCP scope, to do so only a domain admin account can do.  So I have installed and create a scope on Sev2 using the Domain Administrator Account.

I logged in with DHCP administrator on serv2 and opened the DHCP Console or role and I found it looking this way:

DHCP No access

After thorough research I found out that a Domain DHCP Administrator can only work on DHCP that is installed for that specific DC server.


Solution was to add the user to the serv2 pc local users and groups DHCP Administrators group as follows:

DHCP Local Administrator
