So with the big outage today, I did some quick looking around. Just wondered if there were any DNS registrars that have decent security practices. It’s tough to find. Not that the attack on GoDaddy was a security breach, it wasn’t. It was a Denial of Service attack, not a […]
Qwest / Centurylink DSL Web site timeouts, hangups, or failures while running a firewall or router with static IP addresses. Recently I setup the Qwest DSL service in my home. It worked great, but after a couple days I started to get hang ups and timeouts or hangups while browsing […]
Today I ran into a problem while repairing a computer that had a partially cleaned up virus. I completed the cleanup that my client attempted, ran all my antivirus tools, and thought I had everything working. That is, until I noticed the little red shield for Windows Security Center. It […]
Quick note about using chntpw command to reset Windows passwords. Mostly, I just couldn’t remember what the command line program was or the switches. Boot to System Rescue CD. mount the Windows drive RW (mine was RO) cd to the config dir: cd /mnt/sda1/Windows/System32/config Backup your sam,security,system,software (just copy them […]
If you are like me, you don’t have time to run nmap scans and do other network maintenance. Running nmap is one of those really fun and useful tools that are easy to use, but since I rarely use it, I never remember the options. Â Today was one of those […]
MsMpEng.exe – Antimalware service executable I generally do not have any issues with Microsoft Security Essentials. It just works, and does its job quite well. Â From time to time I notice some weird issues on my client computers, where MsMpEng.exe (Antimalware service executable) is using way too many and high […]
I had a client recently that had their browsers hijacked. Everything they typed in the browser ended up redirecting them to some test_s.php file at “www.fes.skâ€. (Don’t open that, or you might end up with a virus! I just wanted people to find this in case it might help clean […]
Microsoft Security Essentials MsMpEng.exe – Antimalware service executable using high CPU Time I have Windows 7 Ultimate x64, but I think this might be problem in any version. I keep having issues with Microsoft Security Essentials MsMpEng.exe using high CPU Time and hogging the cpu.  Basically, using a large amount of resources, like […]
This is just another one of those things that didn’t make any sense and only partially does now. At least NOW I know there is more at play here than the simple solutions in Samba using create mask and create directory mask. In Linux, that’s how I would get around […]
When using Folder Redirection on a Windows 2003 server, the default policy is allow only ownership and permissions to the user. No admin account would have access to this folder. For example, you create a Group Policy to redirect user’s My Documents folders to a home directory on the server. […]
Recently I went to reset a user’s home directory permissions on the server to allow them full control over each file/folder in their home directory. I setup all the normal accounts and of course the actual user account, with Full Control. I then went into Advanced and selected “Replace permission […]
I love how people always say that a software firewall like IPCop is a “lesser” product than a hardware system. I ran into one site speaking of Netsentron as a hardware solution. I’d also include Endian Firewall and Untangle when we talk about a “linux based hardware firewall”. Well here’s […]
When you clone or image your Linux hard drive with Ghost or Drive Image (or any other imaging software) you might not be able to load Grub. Usually just running some Grub commands off a Linux System Rescue CD will fix it. I think most any bootable Linux Live CD […]
I fought with this one for a while, like several hours. I installed the pptp addon for IPCop, which, by the way, you must Google for. I installed version 0.2.9 (pptpd_0.2.9.tar.gz) and found that on a forum somewhere. If you go to the addon’s from IPCop, you will only find […]
When opening files on the network over mapped drive OR UNC, you receive a “publisher” or “security” warning before running the file. Very annoying. In IE, you add the server or domain to your “local intranet” security zone. In my case, my server was: main.domain.localIt was mapped on O: drive. […]

I am not expert on these things (encryption), but I have done some reading and found some issues with Encrypted File System I don’t like. I may not describe the issues correctly, so this is just my opinion more than anything. 1. In Windows 2000, don’t even bother. It can […]
Uber quick howto: (based on Debian) 1. Make sure ssh, rsync and sudo are installed and working. 2. Add a user account, on remote system. 2.a Add a certificate with openssl or ssh-keygen (look that up elsewhere) 2.b Make sure the cert is unencrypted with no password. Yes, that is […]
I was wondering, though, why use a vpn to tunnel a terminal server connection? Isn’t terminal server encrypted already? Here’s a couple things that I *think* are important:
