Are you able to ping the server by name and IP with the VPN connected? <br />
<br />
It sounds like the server you are trying to RDP into might have network level authentication enable. You can disable that setting by going to the Remote Settings.

I have installed a SonicWall TZ 215 on my network and have SSL VPN all setup. &nbsp;The only problem I am having is when I try to RDP through Virtual Office it comes up with an error stating, &quot;Because of a protocol error detected at the client (code 0x1104), this session will be disconnected.&quot; &nbsp;I can RDP from server to server on the network I'm trying to RDP to but SSL VPN wont let me through the web browser.<br />
<br />
Thanks in advance.

SonicWALL SSL VPN RDP Error

A virtual private network (VPN) is a network that uses a public telecommunication infrastructure, such as the Internet, to provide remote offices or travelling users access to a central organizational network securely. VPNs encapsulate data transfers using secure cryptographic methods and other security mechanisms to ensure that only authorized users can access the network and that the data cannot be intercepted.

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

The Windows operating systems have distinct methodologies for designing and implementing networks, and have specific systems to accomplish various networking processes, such as Exchange for email, Sharepoint for shared files and programs, and IIS for delivery of web pages. Microsoft also produces server technologies for networked database use, security and virtualization.
