DeviceManager Problems
z Use the show routes command (command line only) or view the Routes statistics. Is there a
route to the host?
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.
