Relius Web Site down

Situation: the client has a Website down issue.

Troubleshooting:
I don’t see many related events in the Event Viewer. However, I do see 6 Windows updates waiting for installing. We will schedule to install them.

To fix the problem, first of all, login the Relius web server using administrator credentials. Go to Services and restart IIS Admin Service and World Web Publishing Service.

If above doesn’t fix the problem, restart the Relius web server. It is better to restart it onsite because the site may hang and need press Enter key in console.

DHCP Relay doesn’t work Cisco SG300 switch VLAN

Situation: the client created DHCP for VoIP 192.168.20.0/24 on the Windows server.

On the Cisco SG300, he also configured DHCP Relay for VoIP VLAN. command: ip dhcp relay address 192.168.20.0, ip dhcp relay enable.

However, phone devices on VoIP VLAN don’t receive the IP addresses from the DHCP.

Troubleshooting: on «DHCP Relay Server Table» you need to add the Windows Server IP Address and then, on DHCP> Interface Settings you need to add the VLAN where you want to apply the relay.

 

Routing on SonicWall doesn’t work

Situation: the client created VLANs in their network and configured routing on SonicWall, but the routing doesn’t work and VoIP VLAN can’t access the Internet and data VLAN can’t access the VoIP VLAN.

Troubleshooting: The gateway they tried to add for the routing policy is using VLAN VoIP Ip address (192.169.20.1) on the switch instead of data VLAN IP address (192.168.16.64).


Since the default gateway is in the data VLAN (192.168.16.1), we create a new network object using switch data IP address (192.168.16.64) and replace the IP address 192.168.20.1. That fixes the problem

More details can be found this link: How to configure routing on SonicWall

How to configure routing on SonicWall

Situation: The client create two VLAN, VLAN 1 (192.168.16.0/24) for data and VLAN 30 (192.168.20.0/240 for VoIP. They  would like the VoIP access to the Internet and VLAN 1 can 1. Add VLAN 30 network to the Address Objects in SonicWALL by going to Network>Address Objects. Enter VLAN30 as Name, select LAN as Zone Assignment, Type=Network, Network=192.168.20.0, Netmask 255.255.255.0.

2. Address Objects in SonicWALL by going to Network>Address Objects. access VLAN 30. Enter Name (TopSW2 in our example), Zone Assignment (LAN=VLAN 1), Type (host, don’t put network here because this is for routing), IP address (192.168.16.64 which is VLAN 1  IP address for the switch. Don’t put VLAN 30 IP address here, otherwise the router doesn’t know to route the traffics).

3. Click Routing under network.

4. Click Add under Route Policies. Enter or select these info: Source=Any, Destination=VALN30, Service=Any, Gateway=TpSW2 (which we added above), Interface=X0 (which SonicWALL connecting to VLAN 1).

5. Click OK to save the configuration.

6. Test it.

How to decrypt Rapid Ransomware files

Workaround 1: Use file recovery software

It’s important to know that the .rapid ransomware creates copies of your files and encrypts them. In the meanwhile, the original files get deleted. There are applications out there that can restore the removed data. You can utilize tools like Data Recovery Pro for this purpose. The newest version of the ransomware under consideration tends to apply secure deletion with several overwrites, but in any case this method is worth a try.

Workaround 2: Make use of backups

First and foremost, this is a great way of recovering your files. It’s only applicable, though, if you have been backing up the information stored on your machine. If so, do not fail to benefit from your forethought.

Workaround 3: Use Shadow Volume Copies

In case you didn’t know, the operating system creates so-called Shadow Volume Copies of every file as long as System Restore is activated on the computer. As restore points are created at specified intervals, snapshots of files as they appear at that moment are generated as well. Be advised this method does not ensure the recovery of the latest versions of your files. It’s certainly worth a shot though. This workflow is doable in two ways: manually and through the use of an automatic solution. Let’s first take a look at the manual process.
Use the Previous Versions feature
The Windows OS provides a built-in option of recovering previous versions of files. It can also be applied to folders. Just right-click on a file or folder, select Properties and hit the tab named Previous Versions. Within the versions area, you will see the list of backed up copies of the file / folder, with the respective time and date indication. Select the latest entry and click Copy if you wish to restore the object to a new location that you can specify. If you click the Restore button, the item will be restored to its original location.
Previous Versions

Apply Shadow Explorer tool
This workflow allows restoring previous versions of files and folders in an automatic mode rather than by hand. To do this, download and install the Shadow Explorer application. After you run it, select the drive name and the date that the file versions were created. Right-click on the folder or file of interest and select the Export option. Then simply specify the location to which the data should be restored.
