When are you having problem to start up Computer Management Console, one of the error you will see in the Windows 2000 error log is;
“Temporary directory is not found or there is not enough disk space …”.
The error message means that Windows is unable to locate Temp Directory (temporary directory). In order to find out system default Temp Directory, Use “echo %TEMP%” to output System Default Temporary Directory folder configuration
If the Temporary Directory is not exist, create one at the sub folder.
Try again to launch your Computer Management Consol, it should works fine now 
find out what is the capability of an network interface, e.g. :
ifconfig -m vr0
configure / set media types of a NIC, e.g :
ifconfig vr0 media 100baseTX
ifconfig vr0 media autoselect
configure / set network time server :
net time /setsntp:0.pool.ntp.org
start the network time services :
net stop w32time
net start w32time
check whether network time is in sync :
net time /querysntp
