Summary
Adding a Windows 2008 x64 server to the DPX Enterprise could cause the management console to suspend operation.
Symptoms
Attempting to add a Windows 2008 x64 node that is running Forefront Threat Management Gateway (Forefront TMG) causes the management console to supend operation.
Advanced Recovery backups, as well as NDMP backups will consequently fail for this node.
The DPX NDMP client log file (*.ncl) will show an error:
Could not connect to NDMP server at host(<HOSTNAME>) on port(10000). Reason(rc=10061)
Resolution
NDMP protocol uses default port 10000, as described by the IANA:
www.iana.org/assignments/port-numbers
On Windows servers running Forefront TMG, the dynamic port range that the operating system can utilize starts with port 10000. Using this port configuration on a Windows server may cause a conflict with the default NDMP port used by the DPX Advanced Recovery service, or any other NDMP implementation.
To work around this issue, configure Windows to start the dynamic port range at port 10001 with the following command on the Windows command prompt, where default settings are: start=10000 and num=55535:
netsh int ipv4 set dynamicport tcp start=10001 num=55534
To activate the new dynamic port range setting, a server reboot is necessary.
Check settings with this command:
netsh int ipv4 show dynamicport tcp
