    I have a Citrix member of domain server currenlty on the local subnet with
    the domain controllers, database server that it accesses. I want to move the
    server to a differnet subnet with a new IP address but have remain in the
    domain. Is this possible and what are the steps involved if so?

    Thanks

  2. There are no "steps". Just do it.

    Domains and subnets have nothing to do with each other,...not even related.

    I must be thinking of sites then. Will IP address for server on new network
    be registered with the DNS server that is on the old network. Name
    resolution should not be an issue either?

  4. Site are only related to Domains in the context of Remote Office Sites
    across slow WAN links where the Sites & Subnets Object manage/regulate the
    Replication and direct Clients to use DCs in their own site for logins. So
    in the end it is still irrelevant to what you are doing.
    There is no "new network" and old "network",...it is all one network,...it
    just has within it more than one subnet.

    If the machine registers itself in DNS when it starts up that is all that
    matters. DNS is relative to NameSpaces which is reflected in the Forward
    Lookup Zones, not subnets,..subnets are irrelevant to DNS. Now Reverse
    Lookup Zones are usually "superneted" to cover all the subnets of a LAN in a
    single Zone, so they are only partially related to subnets. But the Reverse
    Zones most of the time don't even need to exist in the first place.

    Yes I know subnets are sometimes looked at as different "networks", but it
    is really a matter of the "context" of what subject you are talking about
    and what concepts you are dealing with. In this context you have One
    network (the whole LAN) but it consists of more than one subnet within it.

    I should have been more clear. It is actually a different private IP
    network however not a subnet. Two networks are 192.168.0 and 10.2.0.0. Is
    this the same scenario as far as what you are describing here for subnets?

  6. Same thing.
    Doesn't change anything I said.

    If you have a LAN Router sitting between these two "things" then you have a
    LAN with multple IP Segments (more accuarte then saying "subnets") and the
    LAN Router handles the routing between them.

    If there is no LAN Router between them then,..yes,..you need to be a lot
    more precise in your description,...nothing we have said up to now means
    anything anymore and we are completely back at the beginning.

    There is a router sitting in between the two segments. Actually an Cisco ASA
    but it is capable of acting as router between the two segments.

  8. Since an ASA is not really a "router" you need to be really really sure that
    it is operating as a LAN Router with respect to those two IP Segments.

    If it is,..fine.

  9. Yes.
    Just move the server and forget it.
    The DNS "A"Record for the server (listed in the DNS Server service) should
    change to the new IP shortly after the Citrix box boots up.
    The Client's cached DNS resolution to the old IP# should expire in about 30
    minutes from the last time they had to resolve it.

  10. Hello Phillip,

    As an addition for the moving keep in mind that the Citrix server has to
    contact the Citrix license server and also the database/master server in
    the citrix farm.

    Best regards

    There is only one Citrix server in this farm.

  13. As long as the Network is working properly at Layer2 &3 with the LAN Router
    doing what it should that should still be fine shouldn't it? I am assuming
    that these other servers aren't changing IP#? I guess the real thing would
    be if the Licensing Server changes the IP?,...but then that would be the
    same thing even if just the IP was changing and there were no subnets
    involved? I've never messed with Citrix at all as you can see :).
    Terminal Serivces, yes, but not Citrix.

  14. Hello Phillip,

    You are right. I wanted just mention it, because if he uses the ASA, he has
    also to think about opening the port for it. As you said ASA is more firewall
    then router.

    Best regards

    There is only one Citrix Server so it should be the same as the licensing
    server. Would changing the IP address cause an issue with the licensing
    server?

  17. Hello Andy1974,

    No, if you check on the Citrix configuration you see also that it uses the
    servername not ip address.

    Best regards
