Here is a handy document from HP regarding iLO configurations.
Planning and configuration recommendations for Integrated Lights-Out processors
The document cover such things as what are the best practices for deploying iLO in the organization, how to configure iLO and what tools you can use(some scripting examples included), what firewall ports should be opened for iLO to work and some other useful information.

Where is my disk space? Part 1
I had this problems before on SCCM server and it appeared again. SCCM hides somefolder from users but they are in know location. When they are in known location it is easy to unhide them. But what to do if the folder is hidden somewhere and nobody can pin point the location. This is what happened to one of the servers. The server has a partition size of ~72GB the total used space is ~28GB but when I’ve checked the folder size it was saying that all files are using only ~5GB. So where is my disk space gone? Well I suspect that some folder are hidden. So the first thing to do would be to choose option to ‘Show hidden files and folders’ and untick ‘Hide protected oparating system file’ this have not shows the hidden folder for me.
The second option is to use good all Command Prompt and write the following command line:
attrib *. -h -s /s /d
This command remove hidden and system attributes from all the files in the partition. Once that was done a new sub folder appeared that had load of files and it was using ~23GB of disk space.
Win2008 cannot join domain
Here is what happens when you try to do things too fast.
I was imaging 4 servers at the same time, all these servers had the same name but were going to be joined to different domains. I’ve done that many times before but this time after joining 2 servers to the domain I could not join the other 2.
The error that I was getting was:
The following error occurred attempting to join the domain domain.local.
Logon failure: unknown user name or bad password.

SCCM network ports
Here is a good Technet article about SCCM ports that it is using to communicate.
After reading this I think there should be no questions left what ports must be opened on firewalls.

and another win :)
here we go again another win in NCC 🙂
No UUID or Serial number on HP server
Here is interesting that happened while I was trying to image the HP server.
I could not understand why the server would not appear in HP RDP the server is perfectly functioning but HP RDP just would not show it and therefor I could not image it.
When I’ve logged into ILO I’ve noticed that there were not Serial and Product numbers. Also UUID was all zeros.

Quick way of fixing ASP.NET
Probably majority of you know but for those who don’t here is a quick to fix you ASP.NET installation.
First Identify the ASP.NET version that you need to fix.
Then search for aspnet_regiis.exe file. Most likely you’ll find couple of them this is is why knowing the version is important. The file should be located in C:WINDOWSMicrosoft.NETFramework followed by the version number on 32bit systems and C:WINDOWSMicrosoft.NETFramework64 on 64bit systems. After identifying the correct version (in my case C:WINDOWSMicrosoft.NETFrameworkv2.0.50727) open command prompt and change directory to the required one(cd C:WINDOWSMicrosoft.NETFrameworkv2.0.50727). Now type
aspnet_regiis -i
This should take less then a minute. In Application Event log you should see couple ASP.NET events the last one will contain the location where the log file is held. The log file simply tells you what was done.
For more information about aspnet_regiis check MSDN.
Multiple connections to share
One of the errors that I’ve never saw before.
A client computer cannot connect to a network share and here is the error:
\192.168.1.1 is not accessible. You might not have permission to use the network resource. Contact the administrator of this server to find out if you have permissions.
Multiple connections to a server or shared resource by the same user, using more than one user name, are not allowed. Disconnect all previous connections to the server or shared resource and try again.
The computer did not have any mapped drives and that share work ok before.
Command prompt to the rescue. 🙂
In command prompt type net use
You should see a list of addresses and there shoud be something like \192.168.1.1IPC$
Now I need to delete that to do that type net use \192.168.1.1IPC$ /delete
Job’s done.
Fixing leaking CO2 cylinder for planted tank
Majority of planted tank keepers are using Carbon Dioxide(CO2) cylinders/bottles to supply CO2 for the plants. To safe cost many are using Fire Extinguishers(FE). I’ve been using FE for couple years myself but also I’ve been getting problems with them as some of them were leaking through the valve.
Here is a method how to repair the leaking CO2 FE.
The cylinder come with 2 different valves: push and screw valve.
I’ll be showing how to repair the screw valves.
Important: The cylinder does not have to be emptied to fix the leak but for your own safety please do the work on cylinder that is completely empty.

LED stair lighting based on Arduino, Part 5
Well the testing did not went according to plan but I was expecting that. The main problem is because I was planning to use LEDs for lighting up the stairs, but because of festive season they have not arrived yet. So instead of 1W LEDs I got stuck with 10W halogens. 10W might not look alot but the current it needs is ~0.8Amps where as LED would be 0.08Amps. The maximum that ULN2803A can handle on collector is 0.5Amps. So when I’ve got everything connected the lights worked half way and then the chips went dead 🙁
The solution would be to replace ULN2803A with 2x ULN2064 quad Darlington arrays as they can handle much higher currents.
I’m putting this project on hold until I get the LEDs. Hopefully it won’t be long.
