Webroot Secure Anywhere

posted Apr 25, 2017, 7:31 AM by Andrew Chadick   [ updated Apr 25, 2017, 7:41 AM ]

Webroot is pretty amazing, but it scrutinizes everything, even already established programs and files that are determined as safe.  Sometimes you just need to whitelist an application to speed things up a bit, especially when dealing with a corporate network.

Webroot utilizes the hash of a known executable to identify it.  To get the hash of a file or program to whitelist it in Webroot as an override use powershell and the command below.
Get-FileHash X:\Folder\FileName.exe -Algorithm MD5
(where X is the mapped drive letter, Folder is any folder name, and FileName is a program name.)
When powershell dumps the MD5 value, copy and paste it in to the override box. - it's pretty self-explanatory at that point.

Here is the criteria:  You get  Error 0x8007003B: An unexpected network error occurred" when creating a new folder on your Windows 2012 file server from a Windows 10 machine.  

Cut to the chase: it's windows search service on the file server that it is causing the problem, simply stop the service and disable it.  Your users will be able to create and rename folders once again.  This is an active problem, MS is aware.

Chrome Crashing and holding on to old data

posted Dec 14, 2016, 11:50 AM by Andrew Chadick

Every now and again, its a good idea to go in to the advanced settings in Google Chrome and clear some of the built up browsing data. 

However, there is also a setting most don't know about, that helps to maintain build up of data into the Chrome cache. It you open chrome, then copy/paste the below link, you can enable a setting to help maintain this cache.

Terminal Services Firewall Mod

posted Dec 13, 2016, 10:28 AM by Andrew Chadick   [ updated Dec 14, 2016, 12:04 PM ]

A really good idea for your RDP Terminal server, is to create a new blocking rule.  Go directly into Windows Firewall and Advanced Security and create a rule  that blocks IP addresses. Once created, go into the rule and update the IP lists to block a single host or network group.  It's really a good idea to put a UTM with stateful packet filter on your edge, so you can look at the traffic coming in to your network.  Analyze the network usage, and check your standard and non-standard ports you use for RDP.  Log the attempts to access with no connection. These usually show in the tens to several hundred, with KB or small amounts of Megs utilized trying to connect.  Once you have those mapped out, put them in this block list.
