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 […]
I found a ton of help on Google for this “Service Unavailable” issue on the OMA virtual directory for Exchange 2003. Unfortunately, this was not something readily available. Several sites will explain the proper config for all the virtual folders in IIS, which you should obviously follow, but they don’t […]
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 […]
For some reason or other, Firefox does not have the option under the Tabs option items to “force links that open in new windows to open in:”. I have Firefox 2.0.0.7 now, and I don’t have that under Tabs options. But, if you open about:config in your address bar, you […]
Took me a while, again, to figure this out. Thankfully not as long this second time. When you use ADModify.net to set properties on groups of objects in Active Directory, you can use variables. Home directories, in my case, is a big one. When I moved to a new server, […]
The basics of this require that we setup a second CPU to take offsite. This system would have AD loaded, GC set, DNS, and all that stuff needed to run AD separately from the network. Here’s the catch, though. We can’t run this and be current. In a disaster, it […]
Some RAID controllers are not what I call *true RAID* drive controllers. They may have a hardware controller, but they run kind of a fake RAID on the host OS. It’s not really software raid, but the RAID is dependant on the OS. This, as you might guess, causes some […]
MSTSC V6, both in XP and Vista, now asks for credentials EVERYTIME you connect! I want the server to ask, not the client! Add this line to the Default.rdp file located in your My Documents folder. enablecredsspsupport:i:0 Also: authentication level:i:0 You may need to save as another name, then rename […]
The shortest interval to download user email with the Exchange Pop3 connector is 15 minutes. Too long for most people. To shorten that to 5 minutes, you have to update/add a registry value in this key: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SmallBusinessServer\Network\POP3 Connector Add Dword: “ScheduleAccelerator”=dword:00000003 Â It works by dividing the default schedule interval […]
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. […]

Greg Fischer 6/15/07 I used Exchange 2000 on Windows 2000 for this, 2003 might be a little different. Obviously, you need to make sure you have the backups in the first place, this assumes you have done this, and we will only focus on recovery. Also, this is intended for […]
Gregs reasons to NOT send images in the email body Are you ready for my geeky-not-what-you-want-to-hear explanation? Email was never designed to have images. Email programs have “retrofitted” them. They increase the size if each message, sometimes 4-10x and more! When you are talking about a single signature that is […]
Statically/manually define/set duplex on linux network card Use mii-tool or ethtool ////////////////////////////// A Note About Duplex Settings By default, Linux NICs negotiate their speed and duplex settings with the switch. This is done by exchanging electronic signals called Fast Link Pulses (FLP). When the speed and duplex are forced to […]
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 […]
All the logical fixes didn’t work. Reinstall, removed ide drivers, reinstalled again, no worky. I was getting an Error code 39 (and 37 on another machine), and the DVD/CD drives would not show up in Windows. “Windows cannot initialize the device driver for this hardware. (Code 37)” The problem seems […]
In Windows Vista (mine is Business version) my Help and Support would not open. Said something about like: “internet explorer cannot download from / help” For some reason, Dreamweaver 8 install messed this up.� The fix was to tweak the file type association.� I just did� a simple registry update, […]
All these years and I’ve never known how to determine what the “master browser” was on my networks. How many times do you see those event log errors about “such and such is not the master browser” or “unable to get a browse list”. Not that I know how to […]
Event ID 40960 and 40961 “The Security System detected an attempted downgrade attack for server…” In my case, when we logged the user in and opened Windows Explorer to a network share, we received an error. “The system detected a possible attempt to compromise security.” Then in the event logs, […]
