Jeff,
Sounds like a duplex problem. Your switch is hard-coded to 100
full. Is your server? Check Monitor/LAN whether it's full or half. Try
setting the switch to auto/auto and see what the interface comes up with.
Otherwise try setting the switch to 100 half, and see if the errors go away.
Half duplex is much better than a mismatch. Hard-coding both sides to 100
full should be the best combination. Email me offline if you need some help
configuring it on the NW side. Hope this helps.

Subject: OT: (Long) Network Slow
Hi Group,
Sorry for this OT thread, but I need help.
My friend's network has a novell file server and an email server. Users
complain sometimes it takes a long time to open a file or an email
attachment.
All the PCs and servers are connected via two 3500 switches which are
interconnected via gigabit module.
I check the switches and see the port that connecting to novell server has
many errors (see the show interface below), while the other ports seems OK.
FastEthernet0/35 is up, line protocol is up
Hardware is Fast Ethernet, address is 0008.a3d0.f863 (bia 0008.a3d0.f863)
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec,
reliability 255/255, txload 1/255, rxload 1/255
Encapsulation ARPA, loopback not set
Keepalive not set
Full-duplex, 100Mb/s, 100BaseTX/FX

I also use a sniffer to see what is happening. Although not much was found,
I
list the major finding below. They appear from time to time and my lead to
the
problem.
There is no loop on the switches and users have the permissions for the
files.

PC Netware Loops on same request
Netware PC Request Denied
PC Email Ser Ack Too Long
PC Email Ser Window Frozen
Any suggestions are welcome and appreciated.
Thank you in advance
Jeff
