- Hi,
-
- If this performance problem is getting steadily worse and you are not adding
- steadily more traffic to your WAN, then I would say traffic is not the problem.
- Two possibilities come to mind immediately.
-
- First, you may have an intermittent problem on the LAN NIC that supports your
- Macintosh clients. Now, since IPX is quite a bit less "chatty" on the net, DOS
- workstations would not necessarily be so sensative to a poorly functioning LAN
- NIC. So, you might try swapping LAN NICs in the server to see if that takes
- care of the problem.
-
- NetWare for Macintos v3.0 was shipped with a NOTIFY init (v2.1---I think) and
- this utility was associated with very poor performance on the Macintosh when
- logged into the NetWare server. If NOTIFY is installed on the Macintosh, try
- removing it to see if your performance gets better. If it does, you need to
- upgrade NOTIFY to v2.11. This version is available on NETWIRE under NOVLIB8.
- I believe the file name is something like NOTIFY.SIT. Just to be safe, download
- this "Stuffed" file to your Macintosh and UNSTUFFIT there.
-
- Let me know if neither of these suggestions provide you with a solution, and I
- will think of something else. In this event, it would help to have a complete
- network map.

-
- ps. Let us not consider some of the more detailed solutions like IP tunneling
- for now as I do not think your transport protocol is the problem source at this
- point.
