I’m upgrading my NetWare 6.5 servers private network adapter from 100 MB
to a 1 GB adapter. (actually I disabled the onboard 100 MB adapter and
installed a new adapter in a free PCI socket).
After doing this the DNS server stops responding. If I return to the old
100 MB adapter everything starts working again. What am I doing wrong?

NetWare 6.5 Small Biz with both public and private network adapter,
BorderManager 3.8, DNS/DHCP, GroupWise, Apache and some other irrelevant
