Question:

What I want to be able to do, is to list all servers in a specified domain, and their role (i.e. PDC,BDC etc). I'm assuming that you don't know what servers you currently have in your domain, so I don't want to inpt any server names, The "wntServerList" function should allow me to do this, but the results are inaccurate.

Answer:

Apparently there was a problem with the help file for wntServiceAt and wntServerList, whereby a line got wrapped, and all the flags were shifted incorrectly.

The correct flags are listed below:

                    1  All LAN Manager workstation
                    2  All LAN Manager server
                    4  Any server running with Microsoft SQL Server
                    8  Primary domain controller
                   16  Backup domain controller
                   32  Server running the timesource service
                   64  Apple File Protocol servers
                  128  Novell servers
                  256  LAN Manager 2.x Domain Member
                  512  Server sharing print queue
                 1024  Server running dialin service
                 2048  Xenix server
                 4096  Windows NT (either workstation or server)
                 8192  Server running Windows for Workgroups
                16384  Microsoft File and Print for Netware
                32768  Windows NT Non-DC server
                65536  Server that can run the browser service
               131072  Server running a browser service as backup
               262144  Server running the master browser service
               524288  Server running the domain master browser

Question:

We've got 20 BDC's in our organization, 5 are local and the other 15 are on the WAN, which is always connected (frame relay, not some dial-on-access ISDN or anything). When I do a

wntServerList("\\mspdc01","mortenson",8|16)

or

wntServerList("\\mspdc01","mortenson",24)

(which I assume are logically the same), I only see three of the BDCs. Is there a reason I don't see any on the WAN and only 3 of 5 locally? They are all NT4 BDCs that don't get shown. Thanks!

Answer:

Not currently sure, but I think it just dumps the information from the Master browser service. If that does not show the computers, then wntServerList will not either.

Also WANs usually have a router that limits what network packets can go across it, and it may be screening out the normal network chatter where these sorts of things are communicated between computers.

Question:

I'm using:

wntServerList("","",2)

and I've also tried:

wntServerList("","",1)

and also have plugged in a server name for the 1st parameter.

In all cases, the function returns ALL servers AND workstations on the network. NOT just servers OR workstations as one would expect, using the 1 or 2.

If I specify 8|16, it works great for returning the BDC/PDC.

We're running NT4.0, SP5, and WB2000C.

Any idea what the problem could be?

Answer:

All servers have the 1 and 2 bits set, in addition to any other bits. Ie, a PDC is 1 | 2 | 8. If he wants to filter some out, he can use wntServerInfo(3) for each server in the list and exclude and that aren't type 1 and/or 2.

These days most machines are running both as workstations and servers. If you can connect to a machine and see files, then it is running as a server. It has nothing to do with if you have Windows Server installed or anything.

There is a way to peek at the registry and see what version of NT is installed.
