If you receive HP SUM Connection Error or Discovery Failed messages, follow these troubleshooting tips:
Ensure your workstation does not have an existing connection to the ADMIN$ share on the target IP address. If it does, it prevents HP SUM from connecting to the remote server’s share because Windows only allows one connection from a client to a server’s share. This can be verified by entering
net use
at a command prompt. If a share to the target IP address \admin$ share exists, delete it, and then attempt the installation again.Ensure that the target IP address server’s admin$ share is accessible. Validate the target server can be accessed by entering
net use x: \\<ip_address_or_dns_name>\admin$
for the target server IP address or DNS name. When the connection is validated, ensure that it is deleted by enteringnet use x: /d
at the command prompt.Ensure the user ID being used to connect to the target IP address server is part of the administrator’s or Linux root equivalent group. If it is not, HP SUM blocks installation to the target.
Ensure WMI is enabled and running on all Windows target servers.
For Windows target servers, enter the user name in
DOMAIN\USER
format, where<user>
is the administrative user name, and<domain>
is either the NETBIOS computer name or the Active Directory domain name for this user account.For Linux, ensure the SSH port is not blocked by a firewall.
For Linux, ensure that the target server can be contacted through SSH and that the
scp
command is available to securely send files to the target server.Ensure the firewall ports on any routers in the network. For more information, see Network ports used by HP SUM.
The Symantec Endpoint Protection product blocks HP SUM ability to communicate with remote targets if the Network Threat Analysis feature is enabled. Disable this feature while HP SUM is in use on the workstation.
Examine the trace directories for connection problems. For more information, see Collecting trace directories.
Ensure the server has a valid serial number.
