A no WINS Network

By Brian G ·
I was at my friends small office 15-20 users network. They're having problems with a slow network, so I told him I'd take a look at it.
They have two servers, one running MS Exchange/DHCP Server, one running MS SQL Server 7.0. Plus both are used for file and print sharing.

The strange part is:
They are directly connected to the Internet through a 56kb leased line.
The workstations are Win98 and in the IP Configuration has the boxed checked
that says "Use DHCP for WINS resolution".
There is NO WINS or DNS server anywhere, except for the ISP DNS.

Seems to work, but not very well.
The name resolutions/authentication's take a long time.

Is there any reason that you can think of NOT to have a WINS Server on the network?

No. They should use WINS or at least use LMHOST files. They probably have ALOT of broadcasts going on.

Since the clients are trying to find a WINS server (Use DHCP for WINS resolution), and there is no WINS server, the machines are waiting for a response. Finally, they get one from your ISPs DNS machine, after several recursive lookup attempts. Whichever server is set as the PDC in your scenario should have WINS installed pronto! This will most certainly help. Also, if the PDC is not your DHCP server, move DHCP server to your PDC also, so that WINS and DHCP are on the same box. Not really necessary to do it that way, but my experience is that it works better this way. File & printer sharing services running on machines connected directly to the Internet pose a serious security risk. They should consider putting a router in between the servers/workstations and their 56KB leased line.

Good luck!

Right now the network is using NetBIOS over TCP/IP and is using only broadcasts to resolve names. The option to "Use DHCP for WINS resolution" only tells 98 to look to the DHCP server for the address of the WINS server (rather than manually entering the TCP/IP address of the WINS server under the WINS settings of TCP/IP properties). DHCP does not provide resolution. Because they are not running WINS, the setting is really doing nothing.

I believe that WINS would significantly reduce broadcast traffic and speed up their LAN, especially since they are using Exchange and SQL servers in addition to file and print servers.

There really is no down side to using WINS if it is configured properly. Since you are already using TCP/IP, there is no hassle of having to change protocol suites.

By the way, if you are going to install WINS server, I recommend that you do not install it on the same NT box that DHCP server is installed.

No reason not to have it installed and tons of reasons you should. Make very sure that you add the 044 WINS/NBNS IP Address for the WINS server in the Server Options in DHCP so all your clients get the WINS server information. Otherwise you accomplish nothing.
