Printer driver is not installed on this computer error

You receive the following error:

The [print driver] printer driver is not installed on this computer.

Some printer properties will not be accessible unless you install the printer driver.

Do you want to install the driver now?

This is a bug on some HP print drivers. This error appears when the following key value is equal to zero

HKLM\SYSTEM\CurrentControlSet\Control\Print\Printers\[Printer Name]\PrinterDriverData\HPTrayCount

We need to set the value of this key to 0×12 (decimal 18)

If you a couple of printer servers and hundred of printers (like my current environment), you can download a small tool I created call Ctx Print Fix. This tool can scan the printer server for printers with the issue, export results to a text file and fix affected printers.

CtxAdmTools: CtxCertifiedPrinters v1.2 released!

I was working on last weeks with a few 64-bit Citrix farms and I was reading about XenApp 6 Printing this morning on the metro to Downtown DC, so I decided to create a new tool called CtxCertifiedPrinters to list all certified, native, non-native and manufacturer 64-bit print drivers. The tool can export results to a Excel file.

If you are looking for 32-bit print driver tool, I created a tool called PrintCert, on July 2008 (in fact this is one of my first CtxAdmTools).

Create a mobile Hyper-V R2 server on a laptop

How to Create a mobile Hyper-V R2 server on a laptop.

My consulting job requires test lots of applications or builds demos or servers to study new certifications. I download and tested the 30 days VMware Workstation on a Windows 7 Enterprise and then I installed a Windows Server 2008 R2 with Hyper-V R2 in a second partition and compared run both environments for a few days in my old Dell laptop. The winner was Hyper-V.

I found the CPU is the real problem when you run multiples VMs in my old laptop and not the memory, so at least a Quad Core with HT is a required.

The next step was to choose a laptop to run it.

I review dozens and dozens of laptops with a price tag between $1000 to $1500.

I was looking for several features:

- Intel Core i7 Quad Core CPU (720QM or up)
- The machine will support 8GB or more of memory (2 or 4 slots)
- Screen resolution of 1600 x 900 or similar. 15” or 17”
- Will be nice to have 2 hard drives
- 9 cell batteries

Last runners:

- HP Pavilion dv7-4080us $1199 – i7 720QM with 6GB (8GB Max), 1TB (2x500 GB HDD 7200rpm), 17” (1600x900), 9 cell battery, Blu-ray device
- HP ENVY 17-1011NR $1599 - i7 720QM with 8GB (8GB Max), 640GB (2x320GB HDD 7200rpm), 17” (1600x900), 9 cell battery, Blu-ray device
- Acer Aspire AS7745G-6572 $999, i7 720QM with 4GB (16GB Max) 500GB HDD 5400rpm , 17” (1600x900), 6 cell battery, DVD
- Lenovo IdeaPad Y560 $999, i7 720QM with 8GB (8GB Max), 500GB HDD (7200RPM), 15.6” (1366x768), 6 cell Battery, DVD
- Dell Studio 15, $1200, i7 720QM with 8GB (8GB Max), 500GB HDD (7200RPM), 15.6” (1920x1080), 6 cell Battery, DVD

And the winner is HP Pavilion dv7-4080us!

I love this machine. It arrived with Win7 Ultimate and I formatted the hard drive and installed Windows 7 Enterprise and Windows Server 2008 R2 with Hyper-V R2.

Below is a screenshot of current state of my machine:

You can see 6 VMs running on it and I have the CPU at 0% and 4GB of RAM used (I have 2 extra GB of RAM available and can replace the 2GB memory module for 4GB for around $100).

VMs running are:

• BrickDB01 - Windows 2008 R2 and SQL 2008 R2 DB Citrix Datastore
• BrickDC01 - Windows 2008 R2 Domain Controller
• BrickProfiler - Windows 7 Enterprise to profile Citrix Streamed applications
• BrickXA01 - Windows 2008 R2 and Citrix XenApp 6 server
• BrickXA02 - Windows 2008 R2 and Citrix XenApp 6 server
• CONVERG - Windows 7 Enterprise with Office 2010 machin

The only thing I don't like about this machine is the touchpad (you can disable it) and this machine doesn’t include a TPM chip.

MS: Windows 7 move pagefile error

When you move a Windows 7 the pagefile.sys file to another hard drive and restart you computer you receive following error:

Windows created a temporary paging file on your computer because of a problem that occurred with your paging file configuration when you started your computer. The total paging file size for all disk drives may be somewhat larger than the size you specified.

CtxAdmTools: Filter Events v1.0 Released!

Currently I’m working in a client and I need to analyze more than 110,000 logs entries in the security log of Windows Server 2003 with specific words and export the results to a file, I found both filter and find on Event Viewer pretty bad options so last night I created a tool to filter events called Filter Events.

The tool read first 100 events (we can change this limit running filterevents /setup-events) and we can move between these log entries using buttons on right.

We can enter a text string to search inside log message description using text box called Filter Events Containing. The search option will display first 100 events (or any value specified using /setup-events) or less. The search function will scan first 5,000 events by default (we can change this limit running filterevents /setup-max).

We can use the Copy Event to Log button to copy specific event to Event Log and using the Save Report button to export file to .rtf file for further analysis.

The tool is available for download at http://ctxadmtools.musumeci.com.ar/FilterEvents
