This only happens with PCs on the other end of a bridged 56k DDS line. It also affects DOS and W98 clients the same. Clients can log onto the domain ok, and browse. But trying to drag a file, or even right-click it in W98 explorer, cause the machine to hang, and eventually blue screen with a VREDIR VXD error. If I copy to Samba, sometimes it works, but then the file is zero bytes. Copying from Samba sometimes works, but then I cant delete the file locally, I get strange read-only or permission errors in Win98. Is there a problem with the lag of the 56k link somehow? I've seen some failed oplock breaks and a few timeouts in the logs. I can get logs if this doesnt sound like a familiar (i.e. already fixed) problem. Thanks for any help, I'm kind of in a bind here!
