I have a couple of computers that receive "unknown server" messages at least
twice a day. These are windows 98 machines with novell client 3.1 on both.
This is a very small network at a remote site. Only 2 computers, 1 printer,
Netware 3.2 server, and and ISDN router to connect up to our main site. To
add to the complexity, these 2 users login to the local net and in the login
script, it is set to make a connection to our Netware 5.0 server at our main
site for things like GroupWise and a shared directory on this server. It's
kind of messy for management purposes and we plan on upgrading the local 3.2
server.
The "unknown server" messages usually indicate the name of the server at our
main site, so initially I thought it might be something with the router.
But I have also seen the name of the local 3.2 server referenced in the
"unknown server" messages so I think it may have something to do with the
old stuff at the local site. The only way the users can fix this problem is
to down the local 3.2 server and bring it back up again, then everything
maps up fine and works untill the next time.
I've tried replacing the NIC in the local 3.2 server. The problem still
happens. I've noticed some misc errors in monitor and some checksum errors,
but the counts don't seem real high to me, so I would think that if it's
some kind of a cable problem, it would only happen with one computer, but
these troubles occur on both computers. Could it be a problem with the hub?
It's just a small 8 port 100/baseT hub. We did have some problems with the
power supply to it a while back.
The local server is old. It's a Pentium 90 with an older SCSI HD in it, but
I don't see any bad blocks or anything to indicate it's a HD problem. One
thing, I have noticed is that sometimes when I try to copy a bunch of files
from our main network to this 3.2 server, I get messages to the effect of
"An unknown problem is preventing files from being copied" and then I have
to start the copy over.
I'm at a loss on this one and don't want to spend that much time
troubleshooting it because everything will be upgraded, but I'm going crazy
because I get calls everyday from the users about the "unknown server"
messages. The setup has worked in the past and only started happening in
the last 2 months, but I just can't think of anything that may have changed.
One thing about this location is that they do have a lot of power outages,
but everything is plugged into a UPS.
Any help would be greatly appreciated or if anyone can think of something I
may have missed, that would be great.
Thanks,
Mike . . .
