Your work network may have a setup with a shared IP address, and each desktop assigned a port address. If you are just getting to the network server that is probably the case. So the address to put into the remote desktop app needs to be "xx.xx.xxx.xx:yyyy" where the x's are the IP address you tried, and yyyy is the specific port address for your desktop. Get the info from whoever set up your network.

BTW, earlier versions of remote desktop for WM did not allow the "yyyy" string to be input, so you are lucky that you can now do that.
