Sally,
Please take a look at the Support Tools. The Support Tools are located in
two places: on the WIN2000 Server CD in the Support | Tools folder or on the
WIN2000 Service Pack CD in the Support | Tools folder. In addition to
netdom you gain access to several very useful utilities, such as dcdaig,
netdiag, nltest, replmon, etc. The better choice, if available, is the
Support Tools from the Service Pack CD.
I would strongly suggest that you install the Support Tools on all of your
WIN2000 Servers.
HTH,
Cary
