We have a bunch of XP machines that connect to a W2k3 SBS AD server. The server has a few static WINS bindings.
Normally this means the XP machines can go straight to "http://foo/" or whatever.
However, frequently the lookup of 'foo' results in a resolution failure on an XP client. A quick check on the server shows foo resolves just fine. On the client we must ipconfig /registerdns and we have to do this sometimes several times a day. The clients can continue to ping the AD server without loss.
All the XP machines are affected. Any clues what might be causing this? The only diagnostics I have read about so far are to interrogate the AD server - which is operating just fine.
