Are you leaking DNS information?

Are you leaking DNS Information?

“Under certain conditions, even when connected to the anonymity network, the operating system will continue to use its default DNS servers instead of the anonymous DNS servers assigned to your computer by the anonymity network. DNS leaks are a major privacy threat since the anonymity network may be providing a false sense of security while private data is leaking.”

Can’t connect to your shares?   You may want to read this Microsoft article.

If you have problems scanning to a folder, you may want to look into updating firmware on your scanner system.

You can also use PowerShell to detect, enable or disable SMB.

Detect: Get-WindowsOptionalFeature –Online –FeatureName SMB1Protocol

Speed up budget laptops

After a quick get by purchase, I somehow purchased a 1.5Ghz laptop in a hurry.  I always try to look at reviews and go over the hardware to make sure I have a minimum of 2.0 Ghz for the processor and 6 to 8 GB of ram.   Needless to say, the performance was horrible.

Because cheaper laptops sacrifice the CPU and usually use budget CPUs with a GPU on board, the performance can be bad.  What can you do to make it a general purpose laptop that performs OK?  Disable all visual effects.   Right click computer, Properties, Advanced System Settings,  Performance, Settings, select the bullet – adjust for better performance – click OK
