TCP 445 and 139

[Sortid]

Hi, I'm using 7.6.0.1.  Can someone tell me why I need TCP ports 139 and 445 open to back up a SQL server?  In the doco it says it's used for remote registry, but not sure what impact this has on the backup.  I have a SQL server behind a firewall.  I have opened up 1556, 13724, 13720 and I can back the server up successfully.  I noticed was that ports 139 and 445 were being blocked by the firewall between the master server and the client.  The only thing I can't do is get the policy to auto detect what type of server the SQL server is when you add it to a policy.  I can edit host details though.

Thanks.

Front End to/from SQL client hosts also use the "remote registry service" which requires TCP ports 135, 137, 138, 139 and 445.

Hi AJ,

That's the doco that I was talking about.  What is the impact of not having those ports open?

The entry in the TN is for SharePoint:

To backup and restore SharePoint: 

Front End to/from SQL client hosts requires the TCP ports for vnetd/13724 and PBX/1556, bi-directional.

Front End to/from SQL client hosts also use the "remote registry service" which requires TCP ports 135, 137, 138, 139 and 445.
See Microsoft article: http://msdn.microsoft.com/en-us/library/cc288143.aspx  

These ports will be needed if the Sharepoint front-end server and MS-SQL server are separated by a firewall.

TCP ports 135, 137, 138, 139 and 445 are highly exploitable, and our security team will not open them.

Our Sharepoint team is working with Microsoft to find alternatives, but it would be great if Netbackup didn't use them.

So are we certain that Netbackup uses Sharepoint's backup methodology to gather the data?

(by the way, Symantec's doc says "135, 137, 138, 139 and 445" while Microsoft's Doc says "135, 137, 138, 139 or 445" from what we read)
