API to find out server info

I'm looking for a way to find out the root file server that I'm connected.  We are currently running on a Novell network, in transition to Windows 2000. If there's a API or OCX that will do the trick for both, that would be ideal. However, I'm guessing that it'll be 2 different ones.
Who is Participating?
For Novell, if you're using tree logins (as opposed to bindery), and if you have only one login server per container, you would extract the container name from the fully qualified userid then enumerate the servers in the root of that container, looking for the sole login server, i.e., skipping print servers, NWIPs, etc.

If the tree and its' object name were well designed, the server name itself would help in identifying its' function.

Another approach would be to enumerate all of the client's connections, looking further only when you find an attachment to a server in the user's container.

And, yes, there is an API for all of this. You can download the Netware SDK and NovellWin32 SDK for free at:


If I remember right, it's about 85M.

To give you a small glimpse at Netware API programming, here's some code to map a drive (done this way because we couldn't always rely on the presence of the MAP command):

// Map a drive to the specified server
// Returns:
//          Success: 0
//                   If an existing connection is being used,
//                   the returned DriveNumber will be >0.
//                   If the connection is a new one, the returned
//                   DriveNumber will be negative.
// Error returns:
// 1 - Unable to get connection references
// 2 - Unable to get connection handle
// 3 - Attach failure
// 4 - Create context handle failure
// 5 - Unable to get context
// 6 - Unable to authenticate
// 7 - No drive letters available
// 8 - Map drive failure

Works good for an Windows NT computer, but what about for a 9X computer?
Hmm, Environ does work on 95.  Unfortunatly, the only 95/98 machines I have around right now are not on our network.  I'm curious, what did you get when you tried it?
kclearyAuthor Commented:
I'm using the FILE_SERVER variable/property (I didn't see a HOMESHARE one).  On a Win98 PC, there is no variable for FILE_SERVER, so I'm receiving nothing.

For Novell:
Unless you have:
* a standardized login script that sets an environment variable to what you want, or
* a standard drive letter mapping whose properties you can query, then

it will be a real pain to find out what you want.

Much depends on which version of Novell you're running and whether or not you permit multiple connections.  With bindery connections, things are a little easier, but when logging into NDS, the concept of a login server begins to blur, since you don't neccessarily know before hand which physical server you'll be authenticated through.

Hi kcleary,

Take a look on link below, maybe you can find something useful:


'Hope will help.

It appears that there's no way to get the info I need all of the time.  Environ$ works on an NT 4.0 PC, but I haven't been able to get it to work elsewhere.  ryancys link has plenty of good code, but nothing that looked like it would take care of the problem.  I beginning to fear that cookre is right.

I will continue to look at some of your comments and hopefully find a solution.
kclearyAuthor Commented:
Thanks to everyone for the help on this question.  It seems there's no easy way to get the information that we need, but you all gave me some valuable info to help solve our problem.

I have submitted a request to split pts. between everyone.

Thanks again for the help.
Helll all, a Points slplit has been requested and will go as follows:


I have refunded 125 point for the split.  I will accept 75 here for cookre.

kcleary, wyou will need to open 2 New questions, one for falkor and one for ryancys.

Entitle each question (IN THIS TOPIC AREA) *Points for <Expert Name>*    In the comment box type *for your help in question #20171853*  Choose the points you wish to aware 1=75 and 1=50 and submit, and you are all done.
