Please find the attached log. As am new to this tool , i could not interpret/understand the results shown in log. It would be great if you can help me to understand the issue. My Mac IP : 192.168.1.97 Entertainment Device IP : 192.168.1.999 > > 4) If you think it is your application, either in a debugger or with > sprinkled test messages trace your code execution to see how it operates. > In your case, see if SLPFindSrvs actually gets to the point where it sends > a multicast packet, or if it somehow returns early. > I've investigated further on the calls being made internally when SLPFindSrvs is being called. I suspect that NetworkMcastRqstRply is unable to communicate futher hence its not able to detect the SLP Service inabsence of Slpd. I am attaching the SLP Log for your reference. Please provide your analysis on the reports i have provided. Thanks in Advance. Regards, Janakiram

It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense.
