Aman,
Hmm, one of the above normally fixes it ... Marianne has a good point, 100M NIC on media server is madness.
The case should have be opened with the operating system vendor - not Symantec - Status 24 are network / operating system related. I am unsure why Symantec are expected to solve non NetBackup issues ...
When troubleshooting a problem, it makes sense to get those on board who have the best information / experience with the problem, in the case of network issues, and in particular Status 24, as mentioned already, this is very unlikely to be NetBackup. In fact, I don't think I have every seen a status 24 caused by NetBackup personally ... Therefore, the most likely cause of the issue will be the Network or Operating system, hence the suggestion to log the call with those who are 'responsible' for the 'part' most likely causing the problem.
