I am in the process of trying to set up the evaluation edition of SLES 2,
for the purposes of self education and possible deployment in the future.

As part of this, I have needed to install the NetWare client onto a PC for
testing. The installation went smoothly, with no errors, and the machine
was fine, until the PC was rebooted.

At this point, no connectivity to the Internet or to any network service
was possible.

Using ping or any other troubleshooting tool is impossible - they have all
reported winsock errors.

With DHCP enabled on the NIC, packets are being sent out but none are
being received. Even though the Novell server is not yet configured, a
DHCP server already exists on this network and has already passed
addresses to other devices on the network. Setting a Static IP does not
resolve the issue. Reinstalling the drivers for the NIC does not resolve
the issue.

Uninstalling the Netware client does not resolve the issue,

The only errors that are being shown in Event Viewer are as follows:

Application Popup: There was error (DATABASE NOT LOADED) processing the
driver database
The description for Event ID ( 0 ) in Source ( NLA ) cannot be found. The
local computer may not have the necessary registry information or message
DLL files to display messages from a remote computer. You may be able to
use the /AUXSOURCE= flag to retrieve this description; see Help and
Support for details,
Application Popup: There was an error (DATABASE OPEN FAILED) processing
the driver database
NETDDE: Listen Failed: 15

The machine is running Windows XP Service Pack 2. The Novell Client
version was 4.91 SP2. The machine had been freshly booted, had the Novell
Client installed with no errors, tested briefly and rebooted. The machine
had shown no signs of network troubles previously, and no other software
was installed immediately beforehand. The trouble did not start until the
PC was rebooted.

I hope you can assist in this matter, as the only solution I can see at
this point is to completely reformat and reload the computer.
