V2V Ubutu vm issues

Recently I was migrating 2 linux servers using v2v and ran into 2 issues.

1. ERROR - happened at first step where converter logs into VM to do what it has to do using admin credentials. Error was as follows ( Authentication error. Incorrect user name or password. This operation also requires that the source machine's SSH daemon configuration allows remote root login.) Ubuntu is one of the linux instances that does not enable root account as default so every time you need to do admin task you have to type "sudo -s" into command line. Therefore account I was using would not be able to login. Very fast RESOLUTION to this problem is to type in "sudo passwd root". This command enales root account and makes you set the password for the same. Ubuntu does not recommend this so be carefull if you decide to go this route. I personally am the only one administering these two boxes so not much concern for me.
2. ERROR - happened at 99% of conversion. Error was as follows ( An error occurred during the conversion: 'GrubInstaller::InstallGrub: /usr/lib/vmware-converter/installGrub.sh failed with return code: 127, and message: Installing GRUB1 on (hd0)... /vmware-updateGrub.sh: 59: grub:
   not found Error installing GRUB Error running vmware-updateGrub.sh through chroot into /mnt/p2v-src-root ')
• SOLUTION
• Added following code into beginning of /usr/sbin/grub-install file:
• if [ $# -eq 1 -a "$1" = "-v" ] ; then
    echo "grub-install (GNU GRUB 1.99-12ubuntu5)"
    exit 0
  fi

What to look for when installing DHCP on windows server 2008 that is also DC

Make sure DHCP is not running as a system account. This change is not necessary if DHCP is running on member server of domain.

By Using the DHCP Server Snap-In

1. In the DHCP Server snap-in, which is located in the Administrative Tools folder, right-click the DHCP server that you want to configure, and then click Properties.
2. On the Advanced tab, click Credentials.
3. Type the username, domain and password of the account under which you want the DHCP Server service to run. You can use any valid existing user account for this, such as a Domain User account. The account should not be set to expire or have any other restrictions.
4. Click OK, and then OK again to exit the Properties dialog box.

By Using the Netsh.exe Command Line

1. From a command prompt, type netsh, and then press ENTER.
2. From the netsh prompt, type dhcp server ipaddress (where ipaddress is the IP address of the DHCP server that you want to configure), and then press ENTER.
3. Type set dnscredentials username domain password (where username domain password is the user account information for the account under which you want the DHCP Server to run), and then press ENTER. You can use any valid existing user account for this, such as a Domain User account. The account should not be set to expire or have any other restrictions.
4. Type quit, and then press ENTER to exit.

Windows 7 winsxs folder is huge!!!

So I have my desktop set up with "whooping" 50GB c:drive space and 600GB on my data drive and I'm thinking that I will have plenty of space for OS. Well 2 years later I end up with this folder called winsxs in c:\windows. And I'm like whaaaaaat!!! This folder was 13GB on my c: drive and this needed to be fixed asap!. So here I go Gooooogling again to figure out what is this folder all about. It happens to be you do not want to manually delete stuff from this folder as you could seriously mess up your system and various applications might decide not to run properly any more.

So what did I do to fix it?
Open cmd line as administrator and run following from c:\windows\system32 directory: "dism /online /cleanup-image /spsuperseded"

By running this I was able to free up 4GB of space. If you have a better solution please share I would love to hear it.

NOTE: If you tun this you might not be able to uninstall some win updates or service packs any more...

What is consuming space on my PC?

I've been looking for tool like that for a long time now. I used all kinds of workarounds before to get to same result and it always required multiple steps. This tool makes it a ton easier to see where is all that space on the server going to. Besides giving you graphical representation of where the files reside, it also gives you folder tree with size info next to folder and breakdown of which file types are the biggest offenders.

Tool is called WinDirStat and can be found at http://www.windirstat.info/

This tool requires to be initially installed. However, once installed you can copy .exe file to your usb and there you have yourself a transferable USB tool. It can be run directly from your USB device.

Problem opening attachements in Outlook without first saving them.

You get following Error:
"Cant create file: document.pdf. Right-click the folder you want to create the file in, and then click properties on the shortcut menu to check your permissions for the folder."

Why does this happen?
In my findings the cause of this error was due to many documents that had same name stuck in microsoft office temp folder. Let's say you are emailed daily report that is always called report.pdf. After some number of times this document is opened from outlook (I think number is 99 times), you will start receiving above error.

How do I resolve it?
1. Open REGEDIT.EXE and go to Edit -> Find... In the Find dialog box type "OutlookSecureTempFolder" without the quotes and locate that registry key.

2. That key will contain the actual folder location, and will look like:

C:\Documents and Settings\%USER_NAME%\Local Settings\Temporary Internet Files\OLK#\ (where # is a random letter or number)

3. Copy the location of that folder.

4. Click on Start -> Run... and paste the folder location from step #4 then click OK.

5. Windows Explorer will open that folder. Please, delete all files present.

6. Restart Microsoft Outlook and you should be able to open your attachments.
