I am running ISA in inegrated mode cache & firewall. Win2K vpn clients are authenticated OK and can ping internal IP addresses on the LAN behind the ISA Server but cannot resolve netbios names of WinNT or Win9X PC's. They can reslove Win2K PC's though. This is a WinNT domain with ISA server running as a Win2K member server. Does anyone know what the problem is??

Hi David,

1. Make sure the VPN clients are assigned a WINS server address

2. Make sure the VPN clients are members of the internal network domain

HTH,
Tom

Hi Tom,
Thanks for your suggestions. The WINS server address is assigned to the VPN client by the DHCP server just like regular network clients. I can see this by doing an ipconfig on the VPN client while connected. Also the VPN client is a member of the domain; I can log in and browse OK if I attach it directly to the LAN instead of remotely.
I do not have an internal DNS server on my LAN, however. Is this absolutely necessary or will WINS do it for me? (I tried setting up a DNS server but started experiencing network problems with clients whenever they renewed their DHCP leases [Eek!] so I shut it down after about a week [Confused] )

Hi David,

You don't need DNS, but you should be able to resolve the NetBIOS names of all the WINS clients. I would check the WINS database and make sure the clients are registering with WINS.

HTH,
Tom

Hi Tom,
Many thanks for your valuable advice. I had a look at the WINS database and discovered that most of the older servers including PDC & BDC were missing. A quick check of their TCP/IP WINS settings revealed an ip address pointing to a WINS server that no longer exists. (bad bad administrator....sound of wrist being slapped!).
Once I corrected this problem the browsing problem disappeared. Also, looking at the WINS documentation, I've probably reduced my overall network traffic by reducing the number of broadcasts. Once again, Tom, many thanks for your help.
