No Open Files and no active sessions

Too little detail.
When do you get the error message?
Why do you expect to see open files?
What database is this about?

Appreciate your quick response Qlemo:

This is the exact error:

Database Connection Error [Cannot connect to database Socket error on connect. WSAGetLastError return 10060($274C)]

Thanks

10060 is a connection timeout on TCP level. But I did not ask for that message ;-).

Migrated Server from Windows Server 2003 to  2013.  All the FSMO, etc was transferred successfully.

When I  go to files and sharing, there is no open files but there are active sessions. I just need to find out what that is.
Does that help.

You do not need to have open files to have an active NetBIOS session, so this "normal" for a domain controller. E.g. domain members check for group policy changes - you won't see them having open files unless they are doing that just that moment.
So that does not mean anything. It does not stop you from doing anything on the server.

There are few users under the Sessions folder of Shared Folders.
- I need to  track them down ( where it is originating from, etc)
also,
- Any way to reset it or clear it completly

Thanks.

When that server is powered off users get the error message mentioned earlier and once server powered on.. computers create the session (with no open files) and everything then works…

Trying to find out why computers are creating sessions with this server when its not supposed to be running anything.

There is no Windows Server 2013, so I assume you mean 2012.

Best to go into the good ol' Computer Management, e.g. via Server Manager » Tools. You will find something you are more familiar with ;-).

This is on Windows Server 2003

You'll have to log network access on the server or a client when they start the application, e.g. with Process Monitor from www.sysinternals.com - but that might be something needing a lot of effort to be able to drill-down to the culprit.

I have installed Process Monitor.  What exactly should I be checking for please?

Yes it is on the old server. I installed TCPView.. What exactly should I check for please?
