Pop3 Help

[Djbell]

Hi All, I am having problems trying to get POP3 and SMTP running through ISA server. When I do an nslookup from a client PC to the mail server I get the following error.

C:\>nslookup mail.uk2.net
*** Can't find server name for address 192.168.10.1: Non-existent domain
DNS request timed out.
timeout was 2 seconds.

Server: UnKnown
Address: 192.168.10.1

Non-authoritative answer:
Name: mail.uk2.net
Address: 213.239.57.89

At the moment the ISA server is a PDC on my internet network, this machine also houses both the DNS and DHCP services. The server is connected to the internet using a Cable modem. The server has two network cards. One is for the internal network and the other is to connect to the Cable Modem. Browsing the internet is fine from the client PC's. I have setup DNS forwarders for my ISP DNS servers on my DNS server. I have all the necessary Packet Filters and Protocol rules for POP3, SMTP, DNS ect. and there is no TCP/IP packet Filtering set on any of the network cards.

Please Help

Regards

Djbell

Hi,

Your getting the error message because the DNS service cannot resolve the name of your DNS server from the IP address, ensure that you have a reverse zone setup with a record for your server within this.

What sort of error messages are your clients receiving?

Hi Dibell,

I have win2K server with ISA as proxy and firewall. I only use DNS forwder, use ISP's DNS. Client are web proxy client and SecureNAT.

Client can go to Internet, but can not check email by outlook express through ISA server.

Hope get news from you
