How to remotely uninstall software?

There’s a lot of times when you just want to uninstall a piece of software without interrupting the end user, but unfortunately there isn’t an easy, out of the box way to do it. To uninstall software on a local machine without any user interaction, you would do something like this: msiexec.exe /norestart /qn /x {2902F983-B4C1-44BA-B85D-5C6D52E2C441} The last part, after /x is the GUID of installed software. To find out the guid on remote software, download this script from here and run this command: cscript /B SwInventory.vbs RemotePC > RemotePC.txt Open RemotePC.txt and look for GUID. Next you need PsExec from SysInternals. This tool will allow you to run commands on […]

Windows Small Business Server (SBS) 2008 transition / migration to Server Standard 2008 R2

(First appeared here) This is an action plan from Microsoft tech support.  I’m going to be testing this in my Lab over the next week or so.  I’ll post any significant notes or corrections that I find. 1.       Run ADprep on SBS 2008 with the Windows 2008 R2 disk. ·         Insert the media for Windows Server 2008 R2 into the Small Business Server 2008 server. ·         Browse to the following folder: ·         <DVD drive >:SourcesAdprep> Adprep /forestprep ·         Press C, and then press ENTER.

RackSpace Cloud Review

About 4 months ago I tried Amazon EC2 with Ubuntu image and found it somehow difficult to configure the server, especially if you are not familiar with cli. Making an ssh remote connection required downloading few encryption keys from amazon. Linux server images from amazon seem to not have root password, therefore private and I think public keys are created for you to connect with ssh, which make it more secure. It took me about 2 hours to figure out how to use those keys. I worked with Linux boxes before, in fact I never hosted a site on Windows machine, and never will, but I didn’t have to use […]

Auto connect and authenticate to a mapped drive on Windows XP

Lately Windows XP Pro and Home is loosing connectivity to the mapped drive or sometime the user has to double click on on Z drive to initiate the authentication process. In some cases the “remember password” check box is not there either. Which means you have to type username and password every time you reboot. I have looked around for a solution and haven’t been able to find anything yet. In some cases it has been asking for authentication even if i give permissions to “Everyone” on the local and shared permissions. If you run the network setup wizard and enable file and print sharing at the end it may […]
