DNS problem: client can ping server, server cannot ping client

I've got a small home network, MS W2K server, MS W2K pro client, router between connecting hub to internet.  Both machines have fixed IP on local network and single NIC card.  I've recently eliminated all my error messages on the server except two, and I'd like some guidance where to look because my client computer can access the server just fine, but the server computer cannot even ping the client.    These errors are on the server:

Event Type:      Error
Event Source:      DNS
Event Category:      None
Event ID:      4004
Date:            4/10/2004
Time:            1:09:23 PM
User:            N/A
Computer:      MAMAB
Description:
The DNS server was unable to complete directory service enumeration of zone ..  This DNS server is configured to use information obtained from Active Directory for this zone and is unable to load the zone without it.  Check that the Active Directory is functioning properly and repeat enumeration of the zone. The event data contains the error.
Data:
0000: 2a 23 00 00               *#..    


Event Type:      Error
Event Source:      DNS
Event Category:      None
Event ID:      4004
Date:            4/10/2004
Time:            1:09:23 PM
User:            N/A
Computer:      MAMAB
Description:
The DNS server was unable to complete directory service enumeration of zone thebutlers.local.  This DNS server is configured to use information obtained from Active Directory for this zone and is unable to load the zone without it.  Check that the Active Directory is functioning properly and repeat enumeration of the zone. The event data contains the error.
Data:
0000: 2a 23 00 00               *#..    

Some sources say the 4004 errors can be ignored because there's a single server and it comes because AD loads before DNS or vice versa.   I'd consider that if I could ping my client.  My AD zones are:

SoA            mamab.thebutlers.local
Name server      mamab.thebutlers.local., admin.thebutlers.local
Host            192.168.0.87
Host            192.168.0.2
Host            192.168.0.1

Reverse Lookup: 192.168.0.x subnet standard running
SoA            mamab.thebutlers.local
Name server      mamab.thebutlers.local., admin.thebutlers.local

The user making the requests to access the client server is the admin on the server with admin rights on both machines (explicitly stated because I was trying to resolve this problem).

I ran dcdiag and netdiag.  Passed all tests, except these tests were skipped in netdiag:  WINS server test, trust relationship test, WAN configuration test.

Where should I start troubleshooting?  Thanks,

First thing we need to know is if you can access any other resources from the server..  such as the internet, for example...

If so, stop and restart the Netlogon Service on the server.

And open a command shell and run:  ipconfig /registerdns

Yes, I can access the interet from the server.  I stopped and restrated Netlogon.  I ran ipconfig /registerdns.  I waited 20 minutes and checked.  It is still true that my server cannot ping the client (although it does, and always has, recognize the proper ip address associated with the windows computer name for the client).

Do you have a firewall setup on the client..??  If so, that would stop ICMP packets..

Try moving the wires on the router to different ports..  Might try looking at the routing table on the router..  may show you something...

Yes, that was it.  When my router went down I restarted the firewall on the client.  When the new router was installed, I forgot to disable the firewall.  Thus blocking my own server.  All is well, and fast, fast, fast!  Thanks.
