- We have a group of Macs in another building at our site
- that log on daily to our office's Novell server. The
- Macs are in another Appletalk zone and on a different
- subnet on the other side of a couple of routers on our
- site-wide network.
-
- At first things seemed to be running pretty well, but
- during the last few weeks the Mac users have reported
- serious problems with slowdowns and cursor freezing.
- Typically what happens is they will be typing in Word or
- QuarkXPress and the cursor will freeze for 5 to 15
- seconds. Eventually it comes back, but sometimes some
- of the text is lost, particularly if the user was a
- fast typist. This has been happening lately once every
- minute or so, so the problem is more than a minor
- annoyance to the users. Occasionally there are other
- problems, such as mysteriously being logged off the
- server.
-
- We ran a few tests to try to isolate the problem --
- removing cc:Mail's ccNotify init, for example.
- We finally determined that the problem appeared when
- the user was logged into our Novell server. If they
- dragged the server volume into the trash, the problem
- disappeared.
-
- I gather from reading other messages here that the
- answer might be "You have too much traffic on your WAN."
- However, I'm still trying to determine what can be done
- about it.
-
- For the time being users have adopted the workaround of
- only logging on when they need to, but since these
- folks are heavy server users this means logging on and
- off perhaps 20+ times a day. Would establishing some
- kind of tunneling to route traffic probably help? Is
- this an inevitability of the way Macs talk to servers,
- or is there hope in sight for a less delicate protocol
- in the future?
-
- Thanks for any suggestions,
-
