Sitting in the server, I want to programmatically find out which all clients are connected to the print server. The list can be a superset , containing other client names/ips as well.

1) Is net sessions(NetSessionEnum or NetEnumConnection) reliable ?
2) Is WNetOpenEnum function reliable?
3) Is their any other way?

Kindly help.

Richard , Here is what I need:

- I am running the program on a print server.
- I want to get the IPs (or Hostname) of all the connected print clients which have made a connection to the print server.

Can you tell me what specific flags might help in this case?

Sorry that is a totally different issue. You may get some of the information from the netstat command.

This will be way too much information. I have stumbled upon a function called NetConnectionEnum which seems to give what I exactly want. But I am unable to get results out of it. Any ideas?

Not really, since you have not given any clue as to what you are trying or what responses you get. Have you checked the documentation at https://msdn.microsoft.com/en-us/library/windows/desktop/bb525376(v=vs.85).aspx?

NetConnectionEnum returns the connections to a particular share on a server. I am trying it on the local server. I have a printer shared on the local server and I have made a connection to that printer from a different machine. When I run my program on the local server , I expect NetConnectionEnum to return a positive value for "entriesread" , which is an out param. But the function returns success but entriesread =0.
Following are the parameters used.

1.servername = NULL
2.qualifier = share name of the printer.
3.level =1
4.bufptr = address of PCONNECTION_INFO_1 pointer.
5.prefmaxlen = MAX_PREFERRED_LENGTH
6.address of a DWORD.
7.address of a DWORD.
8.address of a DWORD.

Unfortunately I do not have a configuration that I can test this on. I suggest you close this question, and open a new one with full details including the relevant parts of your code.
