Unable to delete driver, print spooler windows vista & 7

According to this article (http://www.mysysadmintips.com/clients/170-cant-remove-printer-drivers-in-windows-7-the-specified-printer-driver-is-currently-in-use) pressing delete driver a second after the print spooler has started is the way to delete the driver. Strange but true, it worked for me! Probably because the driver is loaded a couple seconds after the print spooler has started.
VPN tunnel between Netscreen and Cisco

Recently I had some troubles setting up a VPN between a Netscreen and a Cisco device from the remote party.
We had agreed upon a Preshared Key and 3DES/SHA1 encryption/hash algorithms using main mode and DH group 2. The Cisco side had added group 2 to their isamkp setting but they could not add the same group command to the transform command so my Phase2 had NOPFS set while my Phase1 was DH group 2.
The tunnel still did not come up, debugging was not useful as it was the Netscreen that initiated the tunnel every time and the log just showed an answer from the Cisco with “no proposal chosen”. After looking into their config and a hint on the internet, I configured the proxyID on the tunnel with local address = my WAN IP and remote address = their WAN IP. And that did the trick, tunnel was up.

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.
FORTIGATE : Static routes must have lower distance then default GW

Had this problem on a Fortigate 60B & 60C. Static routes did not work as expected.
The static route did not work until the distance was set to 1 which is lower than the 0.0.0.0 default route who has distance 10. Maybe this is not a bug, but intended behaviour. On Netscreen the 0.0.0.0 default route is always the last to be applied and all other static routes go first.

Concerns VDR 1.2
Solution:
http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1029746
To resolve this issue:
Open an SSH session to the VDR appliance.
Open the /etc/fstab file using a text editor.
Add this line at the end of the file:/dev/sdX# /SCSI-0:1 ext3 defaults 0 0
where
/dev/sdX# is the device name and partition number i.e /dev/sda1
/SCSI-0:1 is the mount point
ext3 is the file system type
defaults is the mount option
0 is the dump option
0 is the file system check optionRun these commands to unmount and remount the volume:
umount /SCSI-0:1
mount /SCSI-0:1The operating system in the VDR appliance should now be able to read the fstab file and remount the volume.
A little help, mount the disk using the GUI then issue command “mount” on SSH with root. This will tell you /dev/sdX# and the /SCSI-#:#
