Title
When testing Windows systems, "high end" ports are being used -
Description
When testing a Windows system, you see high end ports usage.
For example, on Windows 2003 (ports 1025 - 5000) or on Windows 2008/2012 (ports 49152 - 65535). -
Cause
When adding a Windows system, if the "Computer Name" field is not filled in, TPAM will connect the server using WMI to determine the computer's name. WMI uses RPC ports to determine this.
-
Resolution
RESOLUTION 1:
Ensure the "Computer Name" in "System | Details | Information" field has been filled in for all managed Windows systems, this will ensure the WMI calls are not made when using "Test System". Enter the NETBIOS name in UPPERCASE.
RESOLUTION 2:
Configure the firewall on the managed system to allow these ports. -
