You can also P/Invoke the NetServerEnum() API.. it's faster and reference
free BUT it runs only on NT platform..

I don't believe there will be a pure .net solution until yukon. Until
then, you will still have to use SQLDMO.

news:uW**************@tk2msftngp13.phx.gbl... I'm looking for a simple way to get a list of my server off of the
network. Primarily I'm looking for my SQLServers. In VB6 I'd use SQLDMO, but I
was looking for a pure .net solution. Anything?????
