Performance Objects Showing Numbers

2009-10-02T08:29:00.004+02:00

Last week we had a Windows 2003 system with a problem with perfmon. The performance objects displayed numbers instead of names. Very annoying because perfmon is very usefull for tracking bottlenecks.

Here is the solution:

Rebuild the performance counters:

Open "CMD".
Just type "lodctr /R".

Windows 2008 restore registry

2009-09-25T21:27:00.003+02:00

Hi there, today how to restore your registry in Windows 2008.
It can happen that your OS is not booting because the registry is corrupt, here is the solution.

The main registry hives are located in \Windows\System32\config. Named: COMPONENTS, DEFAULT, SAM, SECURITY, SOFTWARE and SYSTEM.

Start your machine with the Windows 2008 install disk.
Choose the "Repair" option.
Go to \Windows\System32\config and rename the 6 files in .OLD.
Copy the backup files from \Windows\System32\config\RegBack to \Windows\System32\config.
Reboot you system. That's it.

By the way; this will also work with Vista.

Exchange 2003: remove a general purpose public folder tree

2008-10-12T23:30:00.008+02:00

Last week I had the task to remove a general purpose public folder tree(Exchange 2003). When I tried to delete the public folder store I get the error message that the store has replicas and that I must move all the replicas.
But what do you do if you have only one server?

The following procedure explains howto delete a public folder store with adsiedit. CAUTION: Be sure you have a backup!

1. Unmount the public folder store
2. Go to Start -> Run and run adsiedit.msc
3. Navigate to the "Configuration Container"
4. Open "CN=Configuration,DC=Domain" -> "CN=Services" -> "CN=Microsoft Exchange" -> "CN=" -> "CN=Administrative Groups" -> "CN=" -> "CN=Servers" -> "CN=" -> "CN=InformationStore" -> "CN="
5. On the right pane you see the appropriate public store, delete it.
6. Start or restart the Exchange System Manager.
Now you can delete the general purpose public folder tree.

That's it for today.

Ubuntu 7.10 audio

2007-11-12T21:54:00.001+01:00

Today I have the new Ubuntu 7.10 on a DELL Latitude installed. This was almost perfect. Only the sound did not work. The onboard sound card is the Intel 82801H HD Audio Controller. For this to work go to "System", "Management" and choose "Synaptic package management". Search on "Linux-backports module" install it (Synaptec then automatically packages which still must be installed). The only thing you have to do is restart the laptop and you will hear the startup sound.

Good luck!
