Network Problem

By ZakM ·
This is the most frustrating problem I have had.
The scenario is as follows, two netware 4.11 servers,with the latest patches.(Compaq proliants)
PC's running netware client v3 through to the latest.Four NT servers.
The problem is that on random occasions workstations will run very slow, i.e each click takes 5-10mins. Even disconnecting from the network from the wall has the same effect. We have narrowed it down to IPX and the netware client software. On removing these from the network settings brings the pc back up to speed.
Not all pc's are effected. Its not a virus.
This will carry on for about 5 days or so and then the problem will just disappear.
It started again on Thursday 13 July , it has been ok for nearly six months prior to that.
Help Help.

Hi!

Since Netware 4.11 supports TCP/IP, try to switch to that.

So you only run TCP/IP.


You can also check network settings on clients and move IPX/SPX prtocol up to the top.

Remove netbeui from clients and the NT Servers if you haven'tallready.

There are only 2 ways you can go pure IP in a Netware 4.11 enviroment. Either install GSNW on NT an create shares to the Netware resources, or install Netware/IP and you will also have to install it on each and every client. I think the problem is with the client. There is a known bug with the IPX Rip part of the client in which it constantly broadcasts to get new route information. This is documented on the Novell Support Web site and only needs a new DLL installing on the workstation. Maybe simply installing the latest version of client32 on one workstation and monitoring how you get on.

Have you sniffed your network with LANalyzer or Sniffer??? There may be a specific packet that can help narrow this down for you. I have seen a similar problem when an undocumented Netware 3.x was responding to the Get Nearest Server SAP from a series of workstations in a mixed environment.

Good Luck.

Have you tried using the MS Client for Netware ?
Depending on what your requirements are from the Netware servers. You may be able to get away with using the MS Client. Of course if you are using ZENWorks, this is not an option as you need the Netware client for Application distribution.

Do you have a mixed environment of NT Workstations and Win95/98 ? Are you at the latest Netware Client v4.7/v3.2 ?
Update Update Update :-)

If you want to eliminate IPX from your Network, I would suggest moving to Netware 5.1 and NDS 8 or Win2000/ADS. Do not attempt to go to IP by implementing Netware/IP.

Are you currently using Cisco switches (specifically the 294. You may also want to check your switch to verify that you have the ports SET to the for the duplex type of the NIC board in the workstation(Full vs Half Duplex). Also check the speed. Do not autonegotiate if you can avoid it.

Check the min physical receive packet size on the NW 4.11 server (should be 1524 for ethernet).

IPX is not very
