In my daily role as a consultant I need to download regularly files from our company FTP and because I work a lot on servers from our customers I find out that File downloads are blocked when I connect to our FTP with Windows Explorer.
Your current security settings do not allow you tu download files from this location.
This problem can be solved different ways. One way is to change the setting manually ‘File Download’ to Enable in IE:
This Powershell script will save you some mouse clicks and of course time, especially if you’re using a lot more PS scripting (like I do):
$HKCU = ‘HKCU:\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3’
Set-ItemProperty -Path $HKLM -Name ‘1803’ -Value 0
After running the above code please log off and log on again in order for the setting to be effecive.
The scipt has been tested on Windows Server 2016.
How to setup a Dynamics NAV Cluster
Windows Server 2012 R2 includes a builtin Network Load Balancer feature. The load balancer inspects the destination address of an incoming packet and forward its to a clusternode.
Multihomed Network Routing
Get int index Route print
Route-p add ip mask 255. Metric 1 if 12
Create an NLB Cluster
Add second node
When you perform a netstat -noa you could encounter a huge list with information. To filter through this list use piping. Like this:
netstat -noa | find “13000”
You now only see processes which listens to port 13000.
Sometimes when installing a new NAV version for a customer I experience problems like a service tier which won’t start. Based on examination of the error in the Application Error log I will then use Telnet to check whether a port is opened or not.
- First install Telnet. By default this feature isn’t installed. You can accomplish this quick with Powershell:
Install-WindowsFeature -Name Telnet-Client -Verbose
- Now you can open a telnet session. First start a Command Prompt. Now type:
telnet ipadress port
- If you see this then the port is open from the current machine to the IP and port you specified:
If you see this then the port is closed:
In the example above I checked if port 1433 is open on the SQL Server. This way I can verify it isn’t a firewall issue.
