I have a problem with a server that has been upgraded to windows 2000 from NT4. I have win98se clients that will at times drop off the network and refuse to log back on until the client system is reset. The systems at times also drop home folder connections, but not other shares. I have all updates installed on the server (sp2 + hotfixes). The clients are not running win9x client for win2000, although this is not suppose to be required. Has anyone else seen this? I didn't have the problem before win2000, could this be a bad upgrade?
