Data Loss Prevention

Have installed one-tier Symantec DLP for testing. Added two agents (manual installation).

Then added all computers (server, endpoints) to domain. Endpoint server has stopped seeing endpoint agents since then.

Have ideas how to solve this issue? I am ready to answer any additional quiestions.

Additional info:

Firewall is disabled,

• Endpoint server and agents are configured to communicate through 8100
• Enforce + Endpoint are running on Windows Server 2008 R2 Ent
• 2 Endpoints: Windows Server 2008 R2 (64-bit agent), Windows 7 Pro (32-bit agent) 

Please check the domain name u entered on DLP agent and the name of endpoint servers are same. w r t IP address or host name.

did you add agents to communicate server using IP ?

can you telnet for the communication port?

Agents were added using IP address of endpoint server, and also communication port is stated directly (8100).

Telnet connection fails with the message: "Could not open connection to the host, on port 8100" (using command "telnet X.X.X.X 8100" where X.X.X.X is endpoint server's IP).

is there any firewall in between blocking the communication?

It was firewall. Was enabled after Windows Server got the updates. Turned off, telnet connected, agents connected. Thank you.

glad it worked :-)

:) thx again. Sometimes obvious things are not obvious until someone tells you where to look :)
