Anyone know why this is ?

DHCP is allocating ip addresses fine and my 2 xp pro PC's are receiving their info fine

I can ping the server by name but the server cannot ping any of the clients

I cannot join a domain because I get network not found

dcdiag, netdiag, nslookup etc all report they are fine

Client sofware-based firewall?

 

tried stopping windows firewall and pinging but same thing, I did not stop it in services though just through the applet.

surely you should not have to run a client server network with no firewall??!?!? at least the DNS/Domain guy at work says that XP and Server 2003 should be able to communicate with windows firewall on

 

sorry sparky sort of is related to the previous thread but I have moved on from there a fair bit

I just get request timed out when pinging from server to client

yet DHCP allocates fine and I can ping server by name and IP from client. most odd.

is the router stopping something ?

 

checklist

yes, 2 clients plus server patched into the router - 1 network card on server

1) does DHCP allocate addresses in scope - yes
2) does dcdiag report everything ok - yes
3) does netdiag pass everything - yes
4) can the server ping the gateway - ie the router - yes
5) can the server ping outside of the gateway ie internet - yes
6) can the client ping the server by IP and name - yes
7) can the client access the net - yes
can the 2 clients ping each other - NO
9) does NSLOOKUP report correct server - yes

it must be firewall related ? but how are you supposed to have any sort of security if you run xp clients and server2003 without firewall on. Microsoft have surely not allowed this - it would be a major flaw in the design as xp clients are meant to be able to communicate with server 2003 with windows firewall enabled.

is there a port I can open ?

 

yep everything now disabled. still cannot ping server to client

 

sorry dude I have been a dick.

Whilst I had disabled ZoneAlarm I had not un-installed it. Therefore some services which I did not recognise but belonged to zonealrm were still running. I un-installed it and hey presto i can ping from server to client

MORE importantly I have joined the domain and I have windows Firewall enabled on both Server and XP Client, and I have not created any additional exceptions to be able to do this.

It would seem very strange if Microsoft had designed it in such a way you could not use windows firewall and therefore be open to attack.

THANK YOU very much for all your help, especiallly Moley and Sparky.

We all learn by stupid mistakes I guess. !!!!

 

Just seen this thread, I've seen that sort of issue before, you would have thought that by clicking disable zonealarm that actually means stop firewalling my box, aparently zonelabs dont see it that way. Good product for a home user but it does appear to carry on working even when you dont want it to.
