Duplicate COM ports on Windows 2003 Server

I configured 3 terminal servers. (2) 16 port and (1) 8 port. I then installed the RealPort Driver for (1) 16 port unit and was assigned ports 3-18. Checked Device manager and ports matched. I then added the 8 port and was assigned ports 19-26. Checked device manager and ports matched. I then added the remaining 16 port and was assigned 27-42. Checked device manager and now I have no port 19 and port 27 is listed twice. I removed all and tried again. Same result. I rebooted the server. No change. Any suggestions? I believe that I am running version 3.2.281.0 of RealPort for Windows 2k
