NT4.0 bdc cannot access network after installation of Service pack on w2k DC

[Guest]

When I install SP2 - 3 or 4 on my w2k DC in range
192.168.1.0 the NT4 bdc in range 192.168.3.0 cannot access
the AD database anymore.
W2k clients in range 192.168.3.0 are stuck on startup with
the dialog box "preparing network connection"

The w2k DC in is DNS server for both ranges and he is WINS
and DHCP server for range 192.168.1.0.
The NT4 bdc is WINS and DHCP for range 192.168.3.0

When I uninstall the SP everything works fine again.

What is the problem?

Post an ipconfig /all from the Win2k DC and a Win2k client, I suspect a
single label domain name causing this.
