Check For Valid Email With Telnet

May 21st, 2008 — 9:58pm

Often, I get asked by folks why an e-mail didn’t reach someone. People get an email that has some cryptic message about why their email didn’t reach it’s intended recipient. While there are an untold number of reasons as to why that could happen, there are a few things you can do to narrow down why it failed.

Regardless, the first thing I always do, is check that the email address is valid. It might sound funny, but just like that hot girl might have given you a phony number, you might have the wrong email address. This happens a lot more often then you might think.

So, how do you check the email? Enter Telnet to the rescue. Don’t worry, Telnet is cross platform. If you have Linux, Mac, or Windows (geez), you can use Telnet to figure out if the e-mail address you’re trying to reach is valid. It’s one of the few things that seem to work on damn near any operating system you can think of.

Shadow Copy Tutorial

June 28th, 2007 — 7:11am

I’ve been a Network Administrator for several years now. One of my favorite features on Windows Server 2003 is Shadow Copy. Shadow Copy is a backup feature that allows you to right click a file, and restore that file to a previous version. If the file is missing, you can right click it’s folder, find the file, and put it back!

Shadow Copy is a snapshot of a drive, at a particular moment in time. It’s comparable to incremental backups, kinda.

While Shadow Copy is not intended to replace regular backups, it’s a very handy tool to quickly find files that users lose all of the time. Note, this is only available on Windows Server machines. Your XP and Vista machines aren’t going to do this.

Heres how to use it:

First, make sure the Shadow Copy service is running in the services mmc. You’re looking for the service called ‘Volume Shadow Copy’. Make sure it’s started, and it’s set to Automatically start. Once you have that covered, you can move on.

On the server you wish to use Shadow Copy on, navigate to ‘My Computer’.

Right Click the Drive (usually ‘C:’) that you want to use Shadow Copy on.

Click Properties

Click the tab ‘Shadow Copies’

Shadow Copy Property Box

Click the enable button if it’s not grayed out. If the button is grayed out, then you’re already running Shadow Copy. We’ll assume you’re not, so at least pretend to click the enable button.

Now, click the ‘Settings’ button. You should see the following dialog box:

Shadow Copy Settings

This is where you set the maxium size you want your shadow copy database to be. As a general rule of thumb, you should never use less than 10% of what your max storage capacity is.

You can also set how often you make Shadow Copies. Keep in mind that the more often you make a Shadow Copy, the more space you will need. The default settings are twice a day, at 7:00am, and 12:00pm. I’ve never found a reason to change this, but I’m sure some of you out there will find plenty of reasons.

Shadow Copy Schedule Settings

Now that Shadow Copy is setup, it’s time to see it in action. Back in the first dialog box we saw , click the ‘Create Now’ button to manually create your first Shadow Copy. Don’t worry, you won’t have to do this again.

Now here’s the sort of tricky part. In order to access the shadow copies that have been created via file or folder, you have to view the folders via net connection.

You can either type in the UNC name of the server (i.e. \\YOUR-SERVER-NAME) and navigate to the folder or file you want, or you can view them over a mapped network drive

Once you do that, THEN you can right click your file, or folder, click on properties, and then click on the ‘Previous Versions’ tab.

Shadow Copy

From here, you can view a previous version, copy or restore. Usually, your best bet is to view the files you want to restore first. It doesn’t help anyone to restore old files that were wrong to begin with. Get someone else’s (think management) OK before restoring files.

How To Map A Network Drive

June 8th, 2007 — 4:37pm

One of the things I have to show people how to do all of the time, is map a network drive. This varies if you’re on a Mac or PC. For this tutorial, we’ll just focus on Windows.

For a PC, You’ll need to know the name of the server that has the files you’re looking for. If you don’t know the name of the server, the IP address will suffice.

Open ‘My Computer’

My Computer

You should something similiar to the above picture. The details will differ with your computer. They’ll look quite different if you’re using Vista.

OK, Now click the ‘Tools’ Menu and click ‘Map Network Drive’

Map Network Drive

Select the drive letter you wish to map, then type 2 backslashes and the folder name in the folder textbox. You should follow that with the path to the folder you want mapped. If you don’t know, you can click the browse button, and locate it.

You should see something like the following by now.

Map Network Drive

That’s all there is to it. It’s pretty much the same for Vista, though the location of the ‘Map Network Drive’ is more direct. Just look in the toolbar of your explorer.
