Citrix: Resolve SSL Error 61 on Windows
Some weeks ago, I had a user call in, saying that she got the following error message when trying to launch applications from our Citrix farm: Luckily, this error is readily remedied, by installing an update for Root Certificates from Microsoft. Once the update was installed, the application launched without further incident.

Disconnect non-mapped drive
From time to time, I have been unable to connect to the UNC path of a network share. The error message I get is: This usually happens when I am remotely connected to another user’s computer. The message is straight-forward enough; so, too, is the solution. You simply need to disconnect from the share. Here’s how: Open a command…

Internet Explorer: Search in the address bar does not work
A while back, a user called in, complaining that he was unable to use the address bar to search, in Internet Explorer 10. He further reported that he had just upgraded from Internet Explorer 9. I originally thought it was due to problems with a plugin, so that was where I started out. After looking at all…

A little over a year ago, I showed you how to fix a broken trust relationship between the client computer and Active Directory. That post has since received a number of comments, and I will address some of them below: @Uncle Reggie: Yeah right, and lose your entire profile and everything you have ever installed.

When first installing Oracle Linux, you may run into being unable to connect to the internet. You may make the mistake of thinking that the problem is with the network settings on the host-side, and try to futz about changing what type of network connection the VM connects to. Don’t bother, it isn’t going to do any good, and you…

Force uninstall when installer is unavailable
Imagine the scene; you are having a problem with a program, and the manufacturer tells you that the solution is a complete uninstall followed by a reinstall. You go to uninstall, and Windows tells you that it can’t find the installer. Looking around, nor can you. So, now you’re up a certain waterway without a certain…

Oracle Linux: Insufficient memory to auto-enable kdump
Remember how I said “you should be all set”, last week? Turns out, I was only partially right. After creating a local user account, Linux also configures kdump, the kernel crash dumping mechanism. When attempting to do so, it returned this error message: As problems go, this one is fairly minor. Kdump does not need to be enabled…

Starting out with Oracle Linux
I have been wanting to learn more about Linux for some time now, and the time has come to transform a desire to action. I have landed on Oracle Linux, for reasons that will soon become clear. As I don’t have any machine to dedicate to this, and because I want to have the ability…
