    I have the following problem:

    Configuration:
    SBS-Server 2003 Premium with SP2 and all updates (exept IE7), no
    ISA-Server installed
    Intel Xeon 3.6 Ghz, 4 GB RAM, 3 x SAS-Harddisk 140 GB RAID-1 + Standby, 2
    x 1 GB-Nic teaming on redundance , rackserver
    working since 08/2006
    function: SBS-Server, Exchange, SQL-Server, Fileserver, DHCP, DNS, WINS <SBS>

    second server with Windows Server 2003 R2 Terminalserver with SP2 and all
    updates (exept IE7)
    Intel Xeon 3.6 Ghz, 4 GB RAM, 2 x SAS-Harddisk 140 GB RAID-1, 2 x 1
    GB-Nic teaming on redundance, rackserver
    working since 08/2006
    function: Terminalserver for 25 Clients, memberserver <WTS>

    third server with Windows Server 2003 R2 with SP2 and all updates (exept IE7)
    Intel Pentium Dual Core [email protected] Ghz, 4 GB RAM, 2 x SATA-Harddisk 150 GB
    RAID-1, 1 x 1 GB Nic, no rackserver
    new since 25.01.2008
    function: data-ware-house-Server with Palo-Excel Plugin,
    memberserver <DWH>

    Network:
    Level-One Gigabit-Switch 16 Port, length of cable 2 m, all server gigabit,
    ip-addresses in same C-class (192.168.120.1, 192.168.120.2 und 192.168.120.3)

    the problem:
    any connection from <SBS> to <WTS> and back (i.e. UNC-name\c$)
    very fast
    any connection from <SBS> to <DWH> and back (i.e. UNC-name\c$)
    very fast

    any connection <WTS> to <DWH> (i.e. UNC-name\c$) is either very slow or
    errormessage
    "Access denied. Contact your administrator for further information. The
    network path was no longer found."

    Both server are memberserver of the sbs-domain, and DNS- and WINS-server
    point to the sbs-server. If I PING the server each other or from the
    sbs-server i receive answers with the full-qualified name of the servers.
    ipconfig /displaydns shows, that the names are found
    if I try a connection with the ip-addresses (\\192.168.120.2\d$) same problem.

    What I did, to solve the problem:

    I removed the new server <DWH> from the domain, then I joined the domain
    again with the sbs-wizard ... problem still here
    on the server <DWH> I did:
    ipconfig /flushdns
    ipconfig /registerdns
    checked later with ipconfig /displaydns, all ok
    but my problem is still here
    checked wins-db and dns: all entries ok

    My question: any tips, what to do next ? Are there known problems with sbs
    2003 and additional servers ?

    Greetings and thanks in advance for any help

    Thank you for your answer

    When I ping the ts from sbs by name it responds with correct ip, when I ping
    the dwh-server from the sbs by name, it respond with correct ip, when I ping
    the sbs from ts or dwh by name all ok, and also when I ping the dwh from ts
    or ts from dwh all ok, always respond with full qualified name.

    why do you think I should disable the teaming, working since 08/2006 in both
    servers, sbs and ts perfectly ?

    thank you in advance

    All working with domain accounts, all situiation with domain-admin-account
    The ts was not connected with the sbs wizard, the dwh was connected with the
    domain wizard

    my problem on swiching off the teaming is, that all the servers are located
    at the ISP, I don't have a DHCP-Server, so I think when switching off the
    teaming, I will lose all connection to the TS. My LEVEL ONE Switch is
    managable, I don't see any errors or duplicate packets on the ports

    The dwh-server is 2 weeks old. What I don't understand is, that the
    dwh-server can perfectly connect to the sbs server, but not to the ts. The
    problem is from the beginning.

    Andy,

    Totally off the wall and just humor me. Plug the DHW and the TS into 2
    different ports on your switch and test again. I had a similar issue a while
    back and it turned out to be the switch communication between those 2 ports.
    Otherwise the switch was working fine.

    Thank you all for the help. I solved the problem.
    Nothing with errors in SBS, TS or W2k, or switch.

    I found some parameters (with a network-tool) in the lan-card, regarding the
    "TCP checksum offload". The parameters were set in a way, that the
    network-card did the calculation of the checksums. In the moment I disabled
    this parameters and the w2k3-system had to do this calculation, all went ok.

    Thank's all for the help.
