“Operation could not be completed because something changed in the remote forest.”

If you see this error, the most common cause is an Exchange rollout update http://www.microsoft.com/downloads/en/details.aspx?FamilyID=a371fa96-e85b-4a4f-8242-15d56595d0ec&displaylang=en was installed on the workstation, but not yet installed on the server itself. Once this update is on the server and on the workstation you should be all set.

I recommend http://networksims.com/, for what you may spend on dinner you get tons of labs http://networksims.com/em_details.html

This is great for testing and for practicing for Cisco CCNA, CCNP and CCIE!

Once you enable logging on your S3 bucket(s) and start collecting logs, the next thing is to try and make sense of them. The logs are created in the form of text files, which you could probably open in notepad or notepad++

The S3 files are really hard to read and understand for most people and there are usually a lot of them for each bucket. I looked at a few software solutions, but like many others they didn’t work for me.

S3Stat, I tried this for a few days, it is only about $5 a month and it does a good job of analyzing the logs. For me, I needed to analyze historical logs which S3 could not process.

SiSense Prism Viewer – This looked like a great solution, but unfortunately I learned this was part of a beta that is no longer available

I used cloudberry explorer to download all the log files for a particular bucket called ABC to a directory called grd. I should also mention we chose to gunzip our log files within the bucket, so once downloaded I had to use WinRAR to extract the files to plan text files. Next open a command prompt, browse to the grd directory containing all of the S3 log files and issue the command copy * combined_log_file    , you will have a file created in the directory containing all of your S3 logs.

Now you need  open Excel and go to File menu and choose Open, in the Open File dialog box, navigate to the folder where the combined_log_file  was created. You may not see it, because by default this dialog will only show files supported by Excel. You need to choose “All Files” in “Files of type” combo box. Locate your file, select it, and click the Open button. You should be presented with the Text Import Wizard. The screenshots below show you what you should do.

Choose “Delimited” in the Original data type options, and click Next. On the next screen, check “Space” and “Tab” in the Delimiters options, and click Finish. Excel will divide data into the right columns and rows.

I have two Cisco 2611 routers and I have two Cisco 1721 routers, This will work with a wide variety of Cisco router gear.

On router A, get to priv exec mode, and get to the first serial interface. Issue the commands below on that interface, also don’t forget a valid ip address, subnet mask (12.173.110.2) (255.0.0.0) and lastly issue a no shut to bring the interface up!

interface Serial0
no fair-queue
service-module t1 clock source internal

On router B, get to priv exec mode, and get to the first serial interface. Issue the commands below on that interface, also don’t forget a valid ip address, subnet mask (12.173.110.3) (255.0.0.0) and lastly issue a no shut to bring the interface up!

This has been out there for some time now. A brand new Firefox add-on called “FireSheep”  http://wiki.twit.tv/wiki/Security_Now_272 lets anyone who is connected to the same Wi-Fi or Ethernet as someone that may be using Facebook or Twitter hack their account easily with just the click of a mouse button.

The link below shows just how easy it is to install firesheep.http://codebutler.com/firesheep

The goods news, there are something’s you can do to protect yourself.

If you use Firefox, these add-ons should do the trick:

• HTTPS Everywhere — this gem from the Electronic Frontier Foundation is about as good as it gets. By default it forces most popular websites to use HTTPS, and you can add your own rules for other sites. This is one of the few add-ons that I use everywhere
• Torbutton — this solution is slightly more involved (it’s for power-users), but if you want to be really secure and anonymous, the Tor network is a fantastic solution
• Force-TLS — this is like HTTPS Everywhere, but doesn’t come with a built-in dictionary of secure sites. Adding them is very easy, though

Chrome users, due to a limitation of the browser, aren’t quite so lucky. There is no way to force HTTPS with an extension. You may have read elsewhere that KB SSL will help you, but it won’t. Instead you need to use a secure SOCKS proxy. This isn’t particularly hard, it does involve a bit of work.

• A guide for Windows users, using SpoonProxy
• A guide for Mac users, using Meerkat — our sister site TUAW has a guide that might help, too

Opera and Internet Explorer users: you too will need to use a SOCKS proxy; just follow one of the guides above.
Ultimately, though, if you use unsecured Wi-Fi networks you will leave yourself exposed. The best solution might not be to install add-ons, but to ask your local coffee shop owner to secure his network with WPA2. The entire problem would go away if big-name websites used HTTPS across the board, too.

It is true, like many others if you applied SP1 to our Microsoft Exchange server you probably have angry Android users who are unable to connect with exchange server. Thanks to  laur.ie for the fix on.

1. Download the 2.2 stock Email.apk from here using the Android browser. Don’t attempt to install it, let it go in to your download folder on your SD card.
2. Open a terminal on your device. I use ConnectBot. Gain root using “su”
3. Run: mount -o remount,rw /system
4. Run: mv /system/app/Email.apk /sdcard/backup_Email.apk
5. Run: cp /sdcard/download/Email.apk /system/app
6. Reboot for good measure
7. Set up your sync

I have been using Windows live for a long time. I have recently started using the Live Writer and I have to say and I really impressed. I recently started to experiment with  the many plugins available. One of the plugins I found useful was the Twitter Notify plugin. You install a new plugin, simply open Windows Live Writer, navigate to manage blog options, choose plugins. If you have no plugins, select get plugins online at the bottom, then search for what you are interested in and following the simple steps!
