Failure to connect with the servers

edited October 2010 in Monitoring Software v12 and lower
We have implemented windows firewall on the servers (windows2003) and the ServersCheck device fails to make the connection with the servers.



Below are the errors we get on the Dashboard:







Last Error



[-2147023174] The RPC server is unavailable.







Last Error



UNKNOWN







Last Error



File(s) not found







Note : The following ports are already open on the firewall.



445 TCP



137 UDP



138 UDP



139 TCP



161 UDP



162 UDP



135 UDP



135 TCP



3389 TCP







Please let me know the solution to fix this issue. Thanks!!!

    RPC is a Windows Security issue regardless of The Monitoring solution you use.



    Assuming that The serversCheck services are running under a Windows Admin Account, Then following might apply:



    - RPC Error

    1. is The "server" service running on The remote host?

    2. is The "server" service tied to The interface (network card) on which The requests arrive from serversCheck? In Windows 2000/2003 or XP you can check this by verifying if The "Client for Microsoft Networks" is available for that network connection. If not, Then click The Install button to add it.

    3. is TCP/UDP Port 139 open between serversCheck and remote host?

    4. is TCP Port 445 open between serversCheck and remote host?

    5. is NETBIOS enabled on computer running serversCheck?

    6. is NETBIOS enabled on remote host?

    7. Does The remote host have more than one IP address? The IP address being called by serversCheck needs to be The first one configured on the remote host. See http://support.microsoft.com/default.aspx?scid=kb;en-us;Q131641 for more information.

    8. If The above do not resolve the issue, then try following article from Microsoft: http://support.microsoft.com/default.aspx?scid=kb;en-us;Q224370
