    Hi,


    The reason for the " RPC Server Unavailable" status should be of any of the following reasons.

    1. Just ping the machine which you want to add and check whether you are able to reach the machine.

    2. Check any System firewall is running in the machine from which you want to collect the logs. If System Firewall is enabled in the machine which you need to monitor, then you need to execute the following command in the command prompt on that machine to enable RemoteAdmin for that machine.

    netsh firewall set service type=REMOTEADMIN mode=ENABLE profile=all ( This commend to be executed in client machine)

    After executing the above command in the client machine, kindly test that machine by using ping command from the machine, where the EventLog Analyzer server is running. Then test the same machine by using Verify Login in the Add Host Details page (from the EventLogAnalyzer UI).

    3. If any other firewall has blocked the machine then you need to open the following RPC ports.

    For DCOM RPC please enable TCP 135 in the firewall. DCOM RPC uses callback for the event receipt which chooses random ports 1024-65534. You can enable 135 for incomming and allow the above range for outgoing calls.

    Check DCOM is enabled on the remote machine. (DCOMCNFG->Default Properties-> Enable Distributed COM on this computer is checked).

    "The RPC server is unavailable" error message when you open Disk Management in Windows XP

    Hi,

    I have review the reply history and learned the issue persists after enable TCP 135 in the firewall for DCOM RPC.

    Please disable the firewall temporarily to check if you can enumerate the luns to isolate the issue. If the issue persists, then the issue may not related to the firewall. If the issue disappear, then firewall is the root cause.

    Hi,

    I've learned that the issue doesn't occur when disable the firewall. Please collect network trace log on both the affected server and the target server for further troubleshooting. To do this,

    a. Download Microsoft Network Monitor Tool from the following link and install it on the two machines.
    http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=983b941d-06cb-4658-b7f6-3088333d062f

    b. Start Network Monitor at "Start" ->"Program"-> "Microsoft Network Monitor 3.4" -> "Microsoft Network Monitor 3.4" on the two machines.
    c. On the left-panel, select LAN connection on the machine and select corresponding connection on the client.
    d. Click "Tools", click "Options", switch to the "Capture" tap, and set the "Temporary capture file size (MB)" to 200 on the two machines.
    e. Click "New Capture", click "Start" on the Capture menu in the two Network Monitor windows.
    f. Now from the affected Windows XP, click a file from the     network share folder to reproduce the issue.
    g. Once the problem occurs, click "Stop" on the Capture menu on the two machines, and click "File"->"Save as" to save the captured files.
    h. Please send the network traces to me via skydrive.
     
    Note: Please inform me the two machines’ IP addresses.

    Thanks for your cooperaiton.
