This is an FYI for an issue that causes the network adapters to disappear in
Windows 2000 running Service Pack 3.

If you installed Dell Server Assistant and have Intel network adapters, then
you have the problem. The file which causes the issue is
c:\winnt\system32\ilansnmp.dll. The 1.39.0.0 version contained a memory
leak, so Intel released a patch which replaced the file with version
1.43.0.0. This repaired the memory leak, but the network adapters would
still disappear.

To verify if you have the problem when you lose the adapters, run regedt32
and navigate to the following key:
HKEY_LOCAL_MACHINE\System\ControlSet001\Control\Class\{4d36E972-325-11ce-bfc
1-08002be10318}

You should see that the subkeys 0000 - 0007 are grayed out meaning the Intel
ilansnmp.dll locked the keys from the system. These are the keys to display
network adapter information. The Microsoft Cluster service relies on these
same keys to fail over the cluster which will no longer happen.

To fix the issue until Intel releases a fix, restart the SNMP service. My
suggestion is to schedule an AT job to run each day to restart the service.
Create a file using notepad with the following lines:
net stop snmp
net start snmp

Save it as snmpreload.cmd and save it to C:\

Next, open a command prompt and create an AT job to schedule the execution
using the following command:
AT 01:00 /every:M,T,W,Th,F,S,Su c:\snmpreload.cmd

This will stop and restart the snmp service each day at 1am. We cannot pin
point when the problem happens other then it seems to take several days.

Good luck. Microsoft and Intel are aware of the issue and are working on a
fix.
