Can't Join Domain

[CID8]

Experts,

My problem is very similiar to many others on this site where people are having trouble joining a domain, only I also can't even ping the server from my XP Laptop. I have a small home network setup thus;
1 x XP Pro Laptop with a 3Com wireless network adaptor
1 x Small Buisness Server 2000 with a 3Com wireless network card
1 x 3Com Wireless access point linking the two to a Symantec Firewall/Router which in turn is connected to a NTL set-top box/cable modem for fulltime broadband connection.
Now the server can ping the AP, the Firewall & the laptop but the laptop can only ping the AP and the Firewall. Being SBS the server has alsorts on it like ISA, Proxy, Exchange, DNS, DCHP etc...and Active Directory of course.

I sure reading these other answers that someone can help with this.

Thanks
Craig

Sounds like you're not allowing intranetwork traffic in your firewall rules. Which device supplies IP addresses? Are you using private IP address ranges, or are they supplied by your ISP? If you can't ping it - it's more than likely not a Server problem although you say the SBS has Microsoft ISA Server on it? You may need to disable it if you're not using it. ISA Server = Microsoft's Firewall...

HTH!

I've solved the pinging problem; having consulted with a colleague whose more experienced in this area he suggested disabling all DHCP and DNS servers and having static IP addresses internaly and adding a line to "HOSTS" file naming my FQDN of the server. This enabled the laptop to ping the server whilst the server was booting until a certain point. This lead me to believe that it was one the services running that was blocking the pinging - so one by one I stopped the services until i could ping. It turned out to be a "Cisco VPN service", so having stopped this service I can ping but i still can't join the domain!!!

Well at least this brings me to same spot as quite a few of the other Posts in this forum.

Any further advice would be much appreciated, thanks
