Unable to start Hyper-V Virtual Machine Management services on the hyper-V Server.

Hey Dude.

I have gone through the issue of  Hyper-V Virtual Machine Management services not starting issue.

On windows 2008 standard server server running hyper-V server we are unable to start Virtual machine services. due to all vms are down infact not visible in Hyper V management console. 
No such error recorded in even viewer. 
During the thought process I realize we have change host name of the 2008 standard host server. after trouble shooting I got an abnormal solution. 
We need Open certificate console of local computer and copy new RDP certificate (Remote desktop) Store in personal and trusted root certification Authorities Store.

Our scenario as below.
1. Windows 2008 standard server.
2. Hyper-V role installed Standalone
3. Standalone server not in domain.

Changes before last working state.
1) Put the hyper Host (Windows 2008 Server) in Active Directory Domain  

Issue Causes
1) Server hostname change to XXX.domain.com
2) Certificate re generate by new Hostname XXX.Domain.com
3) Accessing server via RDP remote desktop connection.
4) New certificate is not shown under Personal and Trusted root Certificate Authority Store.

Resolution :- Log on to the Server Open MMC>Add/Remove Snap-in> Certificate>Computer account>Local computer>

Copy New generated certificate from Remote Desktop Store and paste in Personal and Trusted Root Certificate Authorities Store.



My Journey to setup Another income source ---Still Wondering.

Q. WHY you need Money.... ?
A. Answer May be vary from person to person. I am saying I need money because nothing comes FREE.

Every one want to earn money (Dream), a good money, a huge money, to be a rich and enjoy life.
Some people struggling for basic necessities some people struggling for good life style, some people struggling for social life, eager to respect, A big dreams, never ending needs and expectation, and the solution is the only one MONEY. 
Every one want to earn money as early as possible of course not from the illegal way. WE ARE NOT AN CRIMINAL ! but yes trying to every possible way to earn easy and quick money.

My Initial Thoughts. - To Earn Extra Money

I am also one of you who want to earn huge money in short time. first of all I am salaried person who bind in same monthly budget. so I am seeking some way to get extra income without hampering my office job schedule. By the time I come across online jobs per click pay and online survey program..... I tried a lot but not able to get it work. I also tried my luck in share market. But no luck, I earn a lesson from share market trading. "Its a gamble and do not put your savings or hard money in the market" I booked loss of 1 lacs and withdrawn my interest from trading. 

Step up to the Journey..... :- Set up Another Income source.           

Meanwhile I came across the quote of Warren buffet who are successful trader in share market. the quote that "Never depend on one income source".  so my feeling got stronger to setup another income source. I was impacting recession in the year 2008-09 and laid off from organisation. there was no other income source and stuck in critical situation. some how I manage to survive and restart the profession. by that time it takes 3 year to settle down all things in place.
Now the year 2012-13 I again starting to search another way to get regular income, yes this time I am not looking for some extra income instead looking for  reliable another source of good income.
After searching a lot I come across Google adsense blogging idea. I feel it is good and I can do it. today my approach is not just trying I knew I am going to do this.

Google Adsense, can be a other income source...!! 

I already started collecting information about adsense. its not as easy as it was in the past couple of year. I have collecting information about blogging and adsense policy. I have read many forum and experience of successful blogger who earnit huge amount. I am in the process of get approval from the adsense to my this current blog. lets see... 

I will update on more detail later on...

Thanks...

Windows Sysinternals Suite - procmon utility and trouble shooting easy way.

Hi Friends.

I am fan of the Windows Sysinternals Suite, speciall y the procmon.exe utility.
I am using procmon for any critical issues where Windows error is not familiar or the application is not working expected or throwing unknown error.

Procmon utility is helping to understand complete backend operation cycle and all process, files, registry entry, network involvement of any particular application behavior.

If you need to understand and trouble shoot start the procmon.exe and initiate operation or process. and immediately stop procmon capturing after getting process error.
Now all logs in procmon and just have to apply filter in it.

You have to take closer look at result column "Success and Buffer overflow" is common result.
First filter should apply for exclude success result and buffer overflow result.

You must have to know PID, Process Name, etc - put filter on it and get the error info or files need to action in result. based on my experience I am always searching "Path" with contain filename or path address. check the each process and require option

For any clarification and help do reply.

Unable to Set SQL Database mirroring / Unable to browse resources on AD client computer.

HI,

Here I am sharing my experience and troubleshooting on one of the abnormal issue.

Source Of issue :- On Saturday we generally have a application mock testing. and one of the database is set in mirroring between DR & PR Site for any BCP and disaster recovery.
            For mock purpose we break the mirroring and use DB as standalone instance. After completion of mock testing we restore previous state backup and reconfigure mirroring between PR and DR.
This time we are unable to set mirroring and giving error, "Unable find destination Path"
DR server is up and running properly. we try to browse shared resources but its gave same error.
We are quite confused because nothing is change on DR DB server.we try to access dr server from other servers and from AD server but no luck.
After investing more than 3 hours I came to know that in DNS server there are 2 hostname with same IP address same as DR server IP.
Actually long time back we had formatted DR DB server and put different hostname. so now issue is clear,
We have deleted old DNS entry and refresh computer account of current DR server (Do not delete both account if do you have to rejoin server in AD)
after replicating changes across all domain. we are able to browse the resources and Mirroring as well.

Conclusion is :- issue start with SQL database mirroring and end with DNS stale record i.e. human error.
