Unable to connect to Windows Server 2003 using PocketCloud iOS on iPad's

Ed Grose, Jun 05 09:59 am (PDT):
I've had several users using PocketCloud iOS as well as PocketCloud Windows to connect by Remote Desktop to a small business Windows Server 2003 server through a static IP address for months. Everything was working fine until the past weekend when the server software was updated.
Now, none of the devices will connect through the statc IP address. In addition, when connected wirelessly within the local network, PocketCloud iOS will not connect directly to the sever using the server name, whereas Windows devices will connect directly if the devices are connected wirelessly to the LAN.
Any suggestions as to what may have been changed or how to try to resove the issue?

PocketCloud version is 2.2.134
The devices are iPad’s.
After an extended time of “Loading” dialogue - Error returns on the iPad’s as dialogue box: PocketCloud, RDP Session Disconnected, Exit (button), Reconnect (button) It appears that the “Loading” effort continues to run in the background.
On iPad’s I’m using Remote Desktop Connection (port 3389); Host is static IP address of Verizon broadband connection; Username, Password, Domain are blank (Username and Password are required on Login to servernew).
