Cannot log onto another station (previously
working)
1. Verify all stations are powered up.
2. Reboot the system. Are the network services
loading properly? Watch the screen for error
messages.
3. Verify that the Hub and/or Repeater is powered on
and that the cable connection is secure. Is the Link
OK LED on the hub lighted?
4. If a single station does not come on-line, check the
cable connections to that station. Ping the local
network card, (Ping 127.0.0.1) from the Command
Prompt window. Try logging on again.
5. Is there an authentication issue? Verify that all user
names and passwords match across all systems
being accessed. Passwords are case sensitive.
6. One at a time, swap cables.
Cannot transfer a file over the network
1. Are you having problems transferring a specific
file? Try transferring a known good file.
2. Try transferring a file from Windows Explorer or
the Network Neighborhood environment, rather
than the application. Try Copy and Paste.
3. To verify you have a network problem, try
transferring a file locally, for example from hard
disk to CDR, Tape backup or floppy.
4. Is the problem specific to one remote systems or all
systems?
5. Are all passwords and user names the same across
all systems?
Data transfer is exceptionally slow.
You are storing or recalling patient data from the file
server, an acquisition station or a review station and the
transfer is taking longer than the usual amount of time.
If more than 10 stations are using the network, you may
need to wait until that number is reduced. Heavy
“traffic” will slow network speed.
Login to the network is denied.
You enter the network password, but the system denies
you access to the network.
Verify with the network administrator that you are
entering the correct network password.and that you are
trying to log into the correct file server for the network.
Newly installed station does not communicate
with the rest of the network
Hardware items:
1. Are the remote systems powered on and on-line?
2. Is the hub and/or repeater powered on?
3. Are the correct network cables installed,
recommended type is category 5 UTP.
4. Is each LAN card seated securely into the computer
expansion slot?
5. Are there any resource conflicts between the LAN
card and another component?
6. Is the cable run over the maximum cable length?
7. Are the Link lights lit on the hub/switch and
network interface cards?
Software items:
1. Are the network services loading properly? When
you logon, watch the screen for error messages.
Check the Event Viewer for more information.
2. Are the network services configured properly?
3. Are all necessary protocols loaded?
4. Are the installed protocols configured correctly?
5. Is it possible to ping the local machine (127.0.0.1)
or a remote machine? If both ping commands
result in a reply message the TCP/IP network is
working properly.
6. Do the IP Addresses of each system specify the
same network? (i.e.192.168.1.x)
7. Are the subnet masks the same? (255.255.255.0)
Use Network Neighborhood's Find Computer function
to search the network for a particular computer name or
IP address.
