i have added a win 2k3 server tp my win 2k domain.
the 2k is the dc.
Since this install the network slows, cant ping, services stop and the
network crashes . This happens periodically.

Are there any known issues with adding a win 2k3 server to a win 2k domain.

The problem may be SMB signing or LAN Manager authentication level. In
Windows 2003, default server policy forces all SMB traffic to de digitally
signed which seems to cause a problem in some configurations of XP Pro. In
Local Security Policy for security options try to disable the option for
Microsoft network server:digitally sign communications(always). Ensure you
do this on all machines involved. Run gpupdate /force on the server after
making the change and do the same on the XP Pro machine after or reboot.

Or this, if XP and/or Windows 2003 computers are involved:
New registry entry for controlling the TCP Acknowledgment (ACK) behavior in
Windows XP and in Windows Server 2003:
