    Hi,

    I have ISA 2006 setup and running. I created a rule for access to the isa server using the following protocols "Microsoft CIFS (TCP) and NetBios Session". Withe this rule, I can connect to the isa server drives using \\server name\c$.

    The problem I have right now is not sure what rule to create to enable isa server connect to other systems drives on the internal network. Also when I do nslookup on the isa server, i get:

    DNS request timed out.
        timeout was 2 seconds.
    *** Can't find server name for address 172.xx.xx.xx: Timed out
    Default Server:  UnKnown
    Address:  172.xx.xx.xx

    Note: I can connect to this systems via their IP address but not by their dns names.

    Any one with any idea?

    Thanks

    Hi, you must have a successful name resolution on ISA for DNS. You must use the right IP address of the internal DNS Server in the DNS properties of te internal network adapter on ISA and you shoul also have a look if a system policy rule allows DNS to the DNS Server or a custom firewall rule allows this traffic regards Marc www.nt-faq.de www.it-training-grote.de www.forefront-tmg.de

    Hi,

    Thanks for your response. I had to follow every error displayed under the query to determine what protocols to enable.

    All working fine now.

    Cheers,
    Isaac
