How to fix network print queue installation error 0x0000007e on Windows

Printer-Error

Problem:

The print queue of a HP printer on a Windows 2003 Server (clustered) already has its 32-bit driver installed.

For my new 64-bit Windows 7 client to use the print queue, I installed the 64-bit printer driver on the server.

However, when I connect to the print queue on the 64-bit Windows 7 client, at the end of the installation, it will fail with error:

Windows cannot connect to the printer
Operation failed with error 0x0000007e

Solution:

Delete the “CopyFiles” key from HKLM\Cluster\Resources\<LongString>\Parameters\Printers\<QueueName>

Non-clustered server may have the key at HKLM\SYSTEM\CurrentControlSet\Control\Print\Printers\<QueueName>. Just do a search in regedit using your QueueName to find the right location.

Remember to backup the key before changing the registry.

How to fix copy-paste clipboard issue on Windows 7 Synergy client

Love the cross-platform and open source Synergy keyboard and mouse sharing application. With the newly added built-in encryption, it’s even more secure now.

The only problem I had was the copy-paste clipboard issue. When I hit CTRL-C to copy any text from a Windows 7 Synergy cilent (v1.4.12) running in service mode, it doesn’t get sync’d to my Arch Linux Synergy server (v1.4.12-1) and so I can’t paste it on the server machine. However, it does get copied into Windows 7’s own clipboard.

Workaround: Disable the “Elevate” option on Windows 7 Synergy cilent’s GUI. Some of you will need that elevate setting but copy-paste is more important to me. I already have another keyboard plugged in to the client that I can use for UAC prompts and elevated programs, so disabling “Elevate” is fine for me though cumbersome.

How to create MBR for booting into Windows

I had a dual-booting laptop with Linux Mint and Windows XP on it. After deleting the Linux Mint partitions, it failed to boot into XP because grub can no longer find the MBR. This was the error message:

error: no such partition
grub rescue>

Solution:

Boot into SystemRescueCD and run this command to create a new MBR:

lilo -M /dev/sda mbr

Note: My XP resides in /dev/sda.

How to reduce size of VirtualBox VDI file

Scenario:

VirtualBox version = 4.0.12
Guest OS = Win 7
Host OS = Linux Mint 9 Isadora (based on Ubuntu)

Perform these tasks on all the Win 7 local hard-disks:

  1. chkdsk /F
  2. defrag /X
  3. sdelete -z

Shutdown the Win 7 VM, then run this command on Mint:

$ VBoxManage modifyhd win7.vdi --compact

That freed up 5GB of space for me, a 20% reduction.
