Classic name-resolution timeout delay. Server is looking up names of
client IP-addresses (for its logs etc) and getting no answer. I'd check
how name-resolution is configured on the SCO box. man resolver. I'd add
dummy entries for DHCP scope to hosts or DNS.
"192.168.1.101 dhcp-pc-001" etc

If I felt it necessary to confirm this diagnosis I'd look at the network
traffic. E.g. using Ethereal on the WinXP box via a non-switched hub to
see what DNS Qs are emitted by the Unix box.
