In the event viewer you should see error with Event ID 7024. The IIS Admin Service service terminated with service-specific error %%-2146893809.
Here is a possible fix. For the service to start it needs RSA MachineKey and access to it. The Key is stored in C:UsersAll UsersApplication DataMicrosoftCryptoRSAMachineKeys(for Server 2008) you should see some files in that location with the size of 2 or 3 Kbytes. Look for the file name that starts with ‘C23’. This is the key that is used by Microsoft Internet Information Server. Check the permissions on that key and make sure that ‘System’ and ‘Administrators’ have full control on this key. Once the permissions are set try starting IIS Admin service.
Here is a useful command that I’ve discovered.
Imagine a situation where you have a domain called domain.local with multiple domain controllers DC0, DC1 etc.
For some reason some clients are not working as expected or working slower. In my case it was when I tried to run gpresult /r on some clients it was taking ages to provide full details. To find out if any of the domain controllers is having problems I wanted quickly to change the domain controller that the affected client is using.
Back in the day when Windows NT 4 ruled the world there was a command called setprfdc (set preferred domain controller) nltest does something similar.
Here is an interesting problem with DNS service. I have a new domain with domain controller running Server 2008 R2. I’ve noticed that the server is using more memory than expected. The DNS service is using 605MB of RAM which way too much.
This project has been frozen for some time but I’ve picked it up again, not much progress has been done mainly because I don’t have the electronic components. Buying them in Ireland is a bit expensive so I mainly use Ebay to get them form UK or Asia. The problem with Ebay is that it takes time for the components to arrive.
Anyway I’ve been playing around with shift register 74HC595 as I’ve ran out of digital PWM pins on my arduino. By using only 3 digital pins and 74HC595 I can control 8 LEDs but it is also possible to add more 74HC595 and that means more LEDs without using more digital outputs.
The problem is that for my application 74HC595 is not suitable as it does not support PWM. It is possible to make LEDs fade using code but I did not like the results that I was getting.
The solution is to use TLC5940 which supports PWM. So back to the drawing board
Week 7 and almost no changes are visible in the tank.
I think I will have to spend a bit more time on it next week as it looks like the things are not moving at all.
Here is an interesting issue that I’ve came across while deploying a bunch of HP Proliant DL160 G6 servers.
You restart the server and the it would hang with blank screen, the fans would be running at full speed. To make the server boot you have to remove the power to the server and plug it bak again. This is a known issue and it was can be fixed by updating the Bios firmware of the server to Version: 2011.01.25 (B). Resolved an issue where the system will occassionally hang early in POST with the fans at max speed with the 12LFF hard disk backplane installed.
As with 30L tank this tank did not get much attention for couple weeks. You can clearly see green dust algae on the glass and rock. Hemianthus callitrichoides is actaully doing pretty good and spreading.
