I was setting up multiple wireless access points with the same security and the same SSID. I had no way in windows to tell which AP I was connecting to. I needed to know because as I moved through the office I needed to ensure the computer was jumping onto the AP with the strongest signal in that area. One of my IT staff found a great tool that would tell me this information. This tool is called inSSIDer 2...
Here is a very nice VOIP & Speed Test tool http://mys300.livemeeting.com/myspeed/test/mssvoip .
The nice thing about this tool is it can give you very detailed reports about your connection.
I had some virtual machines running on Hyper-V. I wanted to run some of these on VirtualBox for mobility reasons.
VirtualBox supports running Virtual Machines from VmWare or Hyper-V. VirtualBox can boot VHD’s (Virtual Hard Disks) directly. You do not need to convert the virtual hard drive format.
I copied the VHD’s too %systemdrive%:\Users\USERNAME\.VirtualBox\HardDisks on my laptop...
I came across a site called www.virustotal.com. This site lets you upload a suspicious file to be scanned by multiple virus engines. This is a great tool. I have learned that not any one anti-malware or anti-virus program can catch all viruses. This is the best way to check out a suspicious file without loading multiple anti-virus programs on a computer. Yes this site is completely free and that is why I wanted to share it. This is from the site itself:
VirusTotal is a service that analyzes suspicious files and URLs enabling the identification of viruses, worms, trojans and other kinds of malicious content detected by antivirus engines and web analysis toolbars.
Free, independent service. Runs multiple antivirus engines. Real time automatic updates of virus signatures. Detailed results from each antivirus engine. Runs multiple web site inspection toolbars. Real time global statistics.
Here is a list of the virus engines that Virus Total uses when it scans:
I had this same problem. I reset my phone one day and lost the Skype beta app I had. Fortunately when I logged into the Market it was in my list of downloads and let me download and install it again. I was fortunate to get it back but I never did see it in the market after that.
Spam, or more accurately Unsolicited Commercial Email, is still on the rise, with some estimates measuring it at 90% of all email traffic. It’s a nuisance for users, a storage nightmare for admins, and often a vector for phishing attacks and malware. Using a defense in depth approach, this article provides steps an email administrator can take to protect their network from spam.
Step one-user training
Users should be educated on how their actions can lead to or reduce the amount of spam destined for their inbox. Using corporate email for personal use, subscribing to mailing lists, registering their email address for promotions and giveaways, and forwarding chain mails are all vectors that can lead to spam. Consider disabling html support to prevent downloads that can confirm an address is valid, as well as to reduce the risk of email based malware.
Step two-web content
Step three-tighten up your SMTP gateway
Disabling the verify command (VRFY) on your SMTP gateway makes it that much harder for spammers to check for valid email addresses. If supported, implement a delay before your server responds to a request with its banner. Legitimate email servers will wait for the 220 response before trying to send email, while many programs/scripts used by spammers will not. Your server can then drop email from this misbehaving sender. If your SMTP gateway supports Quit detection, configure it to drop email that it receives from a host that don’t close the session properly. Legitimate email servers end a session with the QUIT command, but many programs/scripts used by spammers don’t.
This site http://www.ninite.com has a list of common software and utilities that are very useful. Basically like the site says you pick your favorite software and it will create one installer with the software you chose. You then download and install of the utilities and software you need in one shot. I had to share this on my blog. Check it out.
May of 2009 I posted a blog on how to Setup Exchange 07 using a Dynamic IP (click here to read it). In this article I suggested a paid email relay service. At the time I was not able find a free email relay but now I have found a free email relay service. This service is www.mxguarddog.com.
It is not only email relay but a SPAM filter as well. I stumbled upon this looking for a free SPAM filter service for one of my clients...
I have run into the issue of not being able to find the Scanpst.exe file where it should be. I even had show hidden files olders and show system files turned on. I did a search and still could not find it. This file typically would be in one of two locations:
- First: C:\Program Files\Microsoft Office\Office12\
- Second: C:\Program Files\Common Files\System\MSMAPI\1033\
We recently had a client that required Google Chrome for a web based app. Google Chrome is easy to download and install. Pretty straight forward and easy enough right? Wrong. Google Chrome installs in
- Win Vista/7 – C:\Users\%username%\AppData\Local\Google\Chrome\
- Win Xp – C:\Documents and Settings\%username%\Local Settings\Application Data\Google\Chrome\
by default. You would think Google would install it to Program Files by default like other applications but it does not.
