Convert MBR in GPT with “gdisk”

With “gdisk” (no, it is not Google Disk ;-)) – you can convert a MBR volume in GPT .

You can get “gdisk” from


GPT fdisk (gdisk) version 0.8.5

Type device filename, or press <Enter> to exit: 1:
Partition table scan:
  MBR: MBR only
  BSD: not present
  APM: not present
  GPT: not present

Found invalid GPT and valid MBR; converting MBR to GPT format.
you don't want to convert your MBR partitions to GPT format!

Most versions of Windows cannot boot from a GPT disk, and most varieties
prior to Vista cannot read GPT disks. Therefore, you should exit now
unless you understand the implications of converting MBR to GPT or creating
a new GPT disk layout!

Are you SURE you want to continue? (Y/N): y

c       change a partition's name
d       delete a partition

l       list known partition types
n       add a new partition
o       create a new empty GUID partition table (GPT)

q       quit without saving changes
r       recovery and transformation options (experts only)
s       sort partitions
t       change a partition's type code
v       verify disk
w       write table to disk and exit

Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING

Do you want to proceed? (Y/N): Y
OK; writing new GUID partition table (GPT) to \\.\physicaldrive1.
Disk synchronization succeeded! The computer should now use the new
partition table.
The operation has completed successfully.

Do not display printers with the same IP address grouped any more

printerWe had many printers that we address with different printer settings (e.g. b/w, color, tray1…). Therefore we use the same windows driver with the same IP with the different settings set.  Since Window 7 / Server 2008, these are then grouped in one printer, which makes the search for the settings not really easy.

But the old printer view is still available by creating a folder with the name


to the bank.

Event ID 215 – Source AppReadiness

errorFor Windows 8.1 or Server 2012 R2, the following error may occur when using local users:

“‘ART:ResolveStoreCategories’ failed for Administrator. Error: ‘Class not registered”

Event ID 215 - Source AppReadiness

The AppReadiness Diest searches the Windows Store for category names that match the already installed apps when the user logs in for the first time. Since a local user is not known to the app store, the event entry is logged. The error can be ignored. See also

How to find out the serial number of a proliant server

serverIn this article I show you how to find out the serial number of a HP Proliant server.

Unfortunately it is not so easy to get the serial number of an HP Proliant server. In the system management homepage it difficult to find.

HP has published a small script. It works quite well.

Simply save the following script as “serialnumber.vbs” and execute it.

strComputer = "."
Set objWMIService = GetObject("winmgmts:" _
    & "{impersonationLevel=impersonate}!\\" & strComputer & "\root\cimv2")
Set colBIOS = objWMIService.ExecQuery _
    ("Select * from Win32_BIOS")
For each objBIOS in colBIOS
    Wscript.Echo "Manufacturer: " & objBIOS.Manufacturer
    Wscript.Echo "Serial Number: " & objBIOS.SerialNumber

The script should also work with other manufacturers, since it uses standard functions.

Event ID 4202 – Source Iphlpsvc

The following error may occur:

Event ID 4202 - Quelle Iphlpsvc

The IP address for the Isatap interface istatap….. was not updated. Update type…

Resetting the TCP-IP stack helps here. Call CMD with adminsitrative rights and enter the following:

netsh winsock reset

After a restart everything should be OK again.
