Upgrade of NT4 PDC to 2000 DC server slows network access

Upgraded NT4 PDC to W2000 server. ADS and DNS installed and working,
using mixed mode (no errors in any logs). Whenever this machine is on
the network, network access slows to a crawl. Any access of network
shares takes much longer than usual. This can't be by design. Checked
the KB and the suggestion is to turn on write caching on the drive which
is turned off during dcpromo. How would this affect the performance of
network shares on other servers (both NT4 and 2000). Is there any
solution. Network is basic - no multiple domains. Any insight much
appreciated.

"Slow" AD networks are usually because of DNS. What kind of clients do you
have on the domain?

For DNS troubleshooting,

Basically your AD DNS server must point to itself in the properties of
TCP/IP for DNS. All AD clients point to the AD DNS server ONLY. Do not give
the AD clients your ISP's DNS servers.
For Internet access set up the AD DNS server to forward requests and list
your ISP's DNS server as the forwarder. This is the ONLY place on your
network that your ISP's DNS server should be listed. Or you can use root
hints for Internet resolution.
