Enable Remote Desktop Remotely with PSEXEC

Download PSTOOLS from microsoft. Unzip to an easy to access location.
Open a CMD command prompt, navigate to the PSTOOLS location.
Execute:

psexec \\machinename reg add "hklm\system\currentcontrolset\control\terminal server" /f /v fDenyTSConnections /t REG_DWORD /d 0

Machinename should be replaced with the computername, ideally you already have admin rights to this PC, for example you run this as the domain administrator. Otherwise the have to supply credentials using -u and -p options.
If you still can’t connect this is most likely the windows firewall.
Execute:
psexec \\machinename netsh firewall set service remotedesktop enable
psexec \\machinename netsh firewall set service remoteadmin enable

Call of Duty Modern Warfare 3 port forwarding (NAT type Open)

If UPNP or DMZ is not an option for you (or you want more security), you can manually forward some ports to get NAT Type OPEN for Call of Duty Modern Warfare 3.
28960 is the port that COD has always used, but you need some steam ports too. The screenshot below might have some ports that are only needed for outgoing connections but documentation is really hard to find about these ports. It works for me with these ports.
COD MW3 port forwarding
To sum up the ports: 28960 (TCP+UDP), 1500 (TCP), 3005 (UDP), 3101 (UDP), 2700-2704 (UDP), 2715-2717 (UDP), 3074 (UDP). You have to forward these ports in your router/modem to your PC. I suggest you read documentation or search the Internet on how to forward ports for your router/model type.

Remember that if you have Windows firewall of another software firewall on your PC enabled you need to add an exception for all these ports in the firewall.

Errors with ntbackup caused by shadow copy.

Portions of FILENAME cannot be read. The backed up data is corrupt or incomplete. This file will not restore correctly.

I would receive this error numerous times in my ntbackup log.

In my case the C: drive would backup without any issue, but the D: drive would show these errors for every file in use.

My backup destination was a 2TB USB disk (G:) with a newer cluster size that is greater than 512. This is not really an issue for storing the backups. But somehow my shadow copy settings on the D: drive were using the G: backup drive as the place to store the shadow copies for the D: drive. And storing shadow copies on a drive with cluster size != 512 will fail. Note: on the G: drive itself shadow copies are disabled. Not needed for backup drive and will fail anyways because of above mentioned reason.

Ubuntu upgrade from 10.10 to 11.04 broke grub

After upgrading my Ubuntu server from 10.10 to 11.04 using the “do-release-upgrade” method, my system would no longer boot.
It was stuck on a GRUB shell. I downloaded the liveCD, booted from that and ran the excellent Boot-Repair utility. I had to install it using apt-get, so you need an internet connection. They should include it in the liveCD. I belive you can also download a Boot-Repair ISO file to boot from.

But the Boot-Repair tool worked great and fixed my GRUB in no time.
I see a lot of problems with GRUB after the upgrade. Maybe it’s a bug that affects people who, in the past, already upgraded from 9.x or 8.x to 10.x. So people who had GRUB v1 at some point in time.
