Network Connectivity Issues
If you receive any of the following frequent errors:
- Msg: Error loading file.
- Msg: File 'usefile.prg' does not exist.
- OBROAD is not an object
- OFORM is not an object
- OAPP is not an object
What causes this?
Anything that interrupts the natural flow and communication with
the workstation to and from the server can cause this error.
These errors occur when A1Law tries to read or write information
from the server and Windows returns an error to A1Law that it
was not successful in reading or writing information to the hard
drive on the server. This may be caused by any one or several
of the following:
- One or several bad network cables at the workstations with
the errors (usually the connector at the end of the cable either
from the computer to the wall or the wall to the hub/router).
- A bad hub and/or router.
- A bad network card on the server and/or workstation.
- Software problems such as very high CPU usage on the server
or workstations due to other programs running thus interrupting
the normal communication flow from A1Law to and from the file
server. The Task Manager on the server and the workstation will
show the percentage of CPU resources being used for each application.
- Incorrectly configured antivirus software. If you are running
Norton, be sure to use the Corporate Edition for networks.
A1Law should usually be able to backup the critical files (which
many backup systems skip) in just a few minutes at most.
Fixing the Problem
- 98% of all network connectivity problems are caused by bad
connectors on the network cable right at the computer itself.
Although, one may also have bad connectors from where the cable
plugs into the wall or at the hub, router or even the connector
on the cable at the server. Of course, the problem could also
be due to a bad cable as well as the connector. One may easily
replace the cable from the computer workstation to the wall.
Sometimes several cables may need to be replaced in order to
fix the problem.
One may run a simple test called DODIR to see if there is a connectivity
problem with that cable. A batch file may be created by your
computer consultant in DOS where the batch file contains two
lines DIR F: and the DODIR so that when run it continuously runs
DIR F: (or whatever the server's drive is) on any workstation.
Then while it is running the directory should constantly scroll
up the screen. While this is happening, hold the network cable
about 1 inch from the computer and gently position it up at the
12 o'clock position for a few seconds, then down, the left and
then right in each position for a few seconds. If the directory
suddenly stops or pauses or drastically slows down, replace the
cable with another one and test it again since you may likely
have a bad connector and/or cable at that workstation.
- Isolate which computers are constantly getting errors. It
may be only one or several. You may look at the Error log in
A1Law\Text\A1Error.txt to see what the errors are and from which
computers.
- Check the Task Manager for CPU Resources being used on the
computer. If there are a lot of resources being used or spikes
either on the server or workstations with the problem, isolate
the issues.
- Make sure your anti-virus software is current and if using
Norton that it is the Corporate Edition. Make sure your anti-virus
software on the workstations are not scanning the server's hard
drive thus causing multiple scans and unnecessary traffic on
the network.
- Remove all spyware.
- It could also be due to a bad network card on the workstations
or file server and/or faulty network drivers that need to be
reinstalled.
- Incorrectly installed A1Law software. Make sure that the A1Law
icon has a Target Location on the C Drive and not the network
drive so that A1Law is running from the workstation and not the
file server. Otherwise, unnecessary traffic will be created on
the network.
- Run the A1Comm program. This program does not "fix"
the problem but rather assumes that there is no such thing as
a "perfect network" and therefore tremendously reduces
the network traffic created with A1Law by using sockets for
communications. This has several benefits including the following:
- Increased reliability and speed due to
substantially lower demand and network traffic.
- Instant message and other communications will be much
faster.
- One may use the "Broadcast" feature which is
not available without A1Comm.
- Integration with other programs such as Outlook will automatically
post to case activity and also one may pull cases directly
from Outlook.
Run A1Comm on the file server. You may create an icon in the startup
folder on the file server called
A1Comm Start Minimize
so that if the file server is restarted then A1Comm will be run
automatically and then minimized. One may also set this up as a
service on the file server. The first time you run A1Comm, click
the Options button then check the box that says
"Enable A1Law For Use With A1Comm" Next, click the LISTEN
button to start the A1Comm program which should run all the time
on the file server. Next, in A1Law click Tools, System, Configure
System Defaults, A1-Comm Settings and check the box Use the A1Comm
server. Click the Save button sign out of A1Law and back in. To
test it, send yourself or someone else an instant message. Make
sure you have properly set your firewall so that it does not block
usage of the A1Comm program.
