Mixed Mode network latency

I'm running an NT 4 network with 1 PDC, 1 BDC 2 member servers, all on the same local network segment. I recently added a new NT 4 Server as BDC, promoted to PDC, then upgraded to Win2K server. The old network used WINS for name resolution, Win2K added DNS to the mix. The upgrade ran without incident, but now Win2K/XP clients are experiencing excessive latency, and some dropped network connections. Rejoining the domain on these clients seems to improve some of the symptoms, but for the mostpart not.

Is there anything obvious I'm missing that would cause this issue, or do I just have to gut it out and upgrade all the servers and get to native mode asap?

Seen this before when in a smaller scale environment. Since Win2k Pro and Xp rely more on DNS for resolution rather than WINS, make sure that you haver your newly upgraded WIN2k DC as a DNS server within their network properties. It may also serveto your benefit to have the domain's DNS suffix added in their properties box as well.

Thanks. I have the clients pointed at the new server for DNS and WINS, and the DNS suffix is there too.

***new development*** seems that the only clients affected are XP, not W2K. Innitially, after login, they work fine, seems like either after a certain amount of idle time they loose connectivity, or there is some intermittant issue that causes the disconnection. This is a real headscratcher.

Are the XP machines going into a powersave mode and the connection is being broken when this happens? Check the power settings in the Display control panel.
