IOLAN DS1/TS2 User’s Guide, Version 3.4

z

If the WebManager or DeviceManager cannot communicate with the IOLAN, verify that the

Security

,

Services HTTP

parameter is enabled for WebManager and

DeviceManagerD

is

enabled for DeviceManager.

DeviceManager Problems

Error Message: 16 bit Windows Subsystem - C:\WINDOWS\SYSTEM32\AUTOEXEC.NT. The
system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose
'Close' to terminate the application.

The error message can be misleading, because it is displayed even if the

AUTOEXEC.NT

file is

actually missing.

To verify whether you have the file, type

%windir%/system32/

in the address bar of an Explorer

window. If there is no

AUTOEXEC.NT

file proceed as follows:

1.

Browse to

%windir%/repair/

(usually

C:\WINDOWS\repair

).

2.

Right-click and Copy the

AUTOEXEC.NT

file.

3.

Browse to

%windir%/system32/

(usually

C:\WINDOWS\System32

).

4.

Right-click inside the window and Paste the file.

The error condition described here may also be the result of corruption of the

AUTOEXEC.NT

file, in

which case the above procedure may be helpful to restore a valid file.

If the above procedure does not fix the DeviceManager installation problem, see

http://support.microsoft.com/?kbid=324767

for the official Microsoft explanation.

Host Problems

Cannot access a host on a local network, verify:

z

The network address is correct.

z

The subnet mask is set correctly and reflects the network configuration.

z

The broadcast address is set correctly and reflects the network configuration.

Cannot access a host on a remote network:

z

Use the

show route

command to verify that there is a route to the remote host. If no gateway is

specified, verify that a default gateway is specified. Ping the default gateway to check if it is
working.

z

Consider the situation beyond the gateway; for example, are intermediate gateways and the
remote host available? Also, check the messages returned by the

ping

command; for example,

that a particular host or gateway is unreachable.

Gateways added into the gateway table are ignored by the IOLAN:

z

Have you used BOOTP and entered a single static gateway in the bootptab file entry? If yes, the
other gateways will be ignored.

Access to host lost after a few minutes.

z

If the route to this host goes through routers, make sure those routers are all sending RIP packets
across the networks.

Login Problems

You have lost or don't know your password (as Admin user).

z

You must reset the IOLAN to its factory default settings using the

Reset

switch on the rear

panel. There is no procedure to access the IOLAN without a password.
