Does anyone know what the error message "Because of a protocol error detected at the client (code 0x1104), this session will be disconnected." means? That and how is it fixed?

Tons of thanks to who ever can.

Well, unfortunately this error can mean many things. Anywhere from a faulty router (if using one) to a trojan. Some simple things that you can check is to make sure that the computer you are trying to connect to does not have a program that is using the same port that you are trying to connect through. Also, clear your dns cache, and possibly reboot both lan connections.

Also, I found this online and hopefully it will help.

This error indicates that RDP is not available to use TCP port 3389l.
Occasionally, RPC provides 3389 to another service and this does not allow
RDP to function. RPC can be isolated and confirmed if you stop the
MSExchangeSA service.

To keep this from happening in the future add the following using regedt32:
(of course, backup the registry keys before making these changes).

Add the following key if not present:

Highlight the following key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc

From Edit menu select "Add Key..."
Key Name: Internet
Class: <blank>

Add the following values if not prestent:

Highlight the following key:
HKEY_LOCAL_MACHINE\Software\Microsoft\Rpc\Internet

From Edit menu select "Add Value..."
Value Name: Ports
Data Type: REG_MULTI_SZ
Data: 3389-3389

From Edit menu select "Add Value..."
Value Name: PortsInternetAvailable
Data Type: REG_SZ
Data: N

From Edit menu select "Add Value..."
Value Name: UseInternetPorts
Data Type: REG_SZ
Data: Y

Then reboot the server and try again.
