PS-SRA, FTP, And Netlet Does Not Work If the Reverse Lookup Is Not Configured in DHCP (6472391)

While using the IP address in the netlet, if the reverse lookup entry for a particular host is not configured in the DHCP server, then the operation associated with that host does not work.

For example, if nslookup.exe ipaddress fails to return the host name then the netlet operations will not work for these IP addresses.

Workaround: Use hostnames instead of IP addresses.
