One of my coworkers just got a new laptop running Windows 7 Pro x64. We use a GPO to deploy the printers to every system, but for some reason it is not working on this system.

I have been breaking my head over this for the past 3 hours now without any result. The strange thing is that gpresult /H seems to indicate that the GPO did run.

The hardware:

• Laptop: Windows 7 Professional x64
• Print server: Windows Server 2008 x64 R1
• HP Color LaserJet 2605dn
• HP LaserJet P2015
• Driver packages on server: HP universal printer driver PCL5, both X86 as X64

Oddities and other info:

• GPO working flawlessly on every other system, including my own Windows 7 Ultimate X64 laptop
• gpresult /H shows the GPO being ran
• Windows Firewall completely disabled on the new laptop

Below is the output for gpresult /H (in Dutch sadly, but I think you'll recognize it):

Like I said, I have been trying to figure this out for the past few hours or so without any result, so you are my last hope.

Any help is appreciated.
