    None of my other servers can access certain things on my SBS server. They get
    RPC Server is unavailable.

    This happens when we use diagnostic tools such as SONAR (FRS software), when
    we use GPResult, and other Diagnostic tools.

    Any ideas?

  3. Hello Amanda,

    Thank you for posting here.

    According to your description, I understand that you get error "RPC Server
    Unavailable" on your SBS. If I have misunderstood the problem, please don't
    hesitate to let me know.

    Based on my research, I suggest we try the following steps to see if we can
    resolve this issue:

    1. Since this issue happen after you use some diagnostic tools, please try
    to do clean boot on the SBS to make sure that this issue is not caused by
    third party services or applications:

    To clean boot the problematic computer, please use the steps below:
    a. Click Start, click Run, and then in the Open box, type "MSCONFIG"
    (without the quotation marks). Click OK.

    b. In the System Configuration Utility (MSConfig) window, click to select
    the Selective Startup button.

    c. Click to clear the check mark from the "Load startup items" below
    Selective Startup.

    d. Click the Services tab, click to check the "Hide All Microsoft Services"
    box, and remove all the check marks from the remained Non-Microsoft
    Services. Please note that the Exchange services could be marked as
    non-Microsoft. Please do not disable those services.

    e. Click OK to close the MSConfig window. Click Yes when you are asked to
    restart your computer in order to enable the changes.

    f. After restarting, please check whether this issue will reoccur.

    g. If there are no more problems, please use the above steps to enable
    services and startup items one by one in order to figure out the root cause
    of this issue.

    2. Do you install ISA Server 2004 on SBS? If yes, I suggest you unchecked
    "enable strict RPC compliance" in the System Policy and in the SBS
    Protected Networks Access Rule.

    Here are the specific steps to turn off "strict RPC compliance".
    a. Open ISA Management
    b. Right click on Firewall Policy and click "edit System Policy"
    c. Click on Active Directory and uncheck "Enforce strict RPC compliance"
    d. Click OK and Apply to apply the changes.
    e. In the Firewall Policy snap-in, locate the SBS Protected Networks
    Access Rule and right click and choose "Configure RPC"
    f. Uncheck " Enforce strict RPC compliance" and click OK and Apply to
    apply the changes.

    If we cannot resolve the issue after we perform the above steps, please
    help me collect some information for further investigation:

    1. What's do you mean by "other servers"?

    2. What's do you mean by "certain things"?

    3. Please capture screenshots on the error messages and send the pictures
    to me at

    4. Do you get this error on SBS or client computers? If the error got on
    client side, does it happen on all clients or individual client?

    5. Gather MPS network report on SBS:

    a. Download MPSrepot_network from
    http://download.microsoft.com/download/b/b/1/bb139fcb-4aac-4fe5-a579-30b0bd9
    15706/MPSRPT_NETWORK.EXE

    b. Run MPSRPT_NETWORK.exe.

    c. The tool will automatically collect the information. This procedure will
    take 10~15 minutes.

    d. Open Windows Explorer, navigate to the folder:
    %SystemRoot%\MPSReports\Network\Reports\Cab\

    e. Send the .cab file directly to me at

    I hope these steps will give you some help.

    Thanks and have a nice day!

    Happy New Year!

    Best regards,

  4. What Post SP2 updates exactly. Can you point me to them? I have run the
    KB936594 update and we do keep the server up to date with the Approved
    updates through WSUS.


    message have you run the post SP2 updates for SBS?

  5. Hello Amanda,

    Thank you for your email. I'm sorry for the delay response due to the
    weekend.

    Please note the newsgroups are staffed weekdays by Microsoft Support
    professionals. Our goal is to provide a one business day response to posts.

    For time critical issues (not business down), we encourage you to contact
    CSS directly for more immediate assistance:

    International Support (non-US/Canada):

    US and Canada:
    http://support.microsoft.com/default.aspx?scid=fh;EN-US;OfferProPhone

    Based on my research on your event error, I think the problem is the
    windows 2003 R2 unable to obtain an auto enrolled certificate from SBS
    2003. I suggest we try the following steps to see if we can resolve this
    issue:

    1. Delete Certification related services from SBS:

    a. Please click Start -> Administrative tools -> Active Directory Sites and
    Services

    b. Select the View menu -> Show Services Node.

    c. Expand the Services -> Public Key Services.

    d. If the problem server (your Windows 2003 R2) is listed under any of the
    certificates node, for example: the AIA node, the CDP node, the
    Certification Authorities node, the Enrollment Services node, or the
    Certificate Templates Node, then delete the server.

    Then, test this issue.

    2. If you have any firewall between SBS 2003 and windows 2003 R2, please
    disable it or ensure the TCP 135 is open in the firewall for both
    directions.

    a. Please disable any 3rd-party firewall (including hardware firewall)
    between SBS 2003 and windows 2003 R2
    b. Please disable windows firewall on windows 2003 R2
    c. Please run CEICW on SBS to ensure ISA server 2004 is correctly
    configured.

    Go through the follow KB and rerun CEICW carefully.

    How to configure Internet access in Windows Small Business Server 2003
    http://support.microsoft.com/kb/825763/en-us

    3. From the MPS report of your SBS, I know you have 2 IP addresses on SBS
    internal NIC. Generally we do not recommend customer to bind multiple IP
    addresses on SBS internal NIC. The multiple IP addresses will cause many
    network connection issues. I suggest you remove one IP address from the
    internal NIC and rerun the CEICW to test this issue.

    If we cannot resolve the issue after we perform the above steps, please
    help me collect some information for further investigation:

    1. How do you connect the windows 2003 R2 to SBS? Please let me know the
    network topology.

    2. Run command "ipconfig /all > c:\ipconfig_R2.txt" and "route print >
    c:\route_R2.txt" on windows 2003 R2, send the files c:\ipconfig_R2.txt and
    c:\route_R2.txt to me at

    I hope these steps will give you some help.

    Thanks and have a nice day!

  6. These RPC Issues existed before we installed Certificates Services and
    before we had any R2 Servers on the network. They are just compounding the
    problem. Our SBS 2003 server has ISA 2004 installed so maybe that helps.
     
    msnews.microsoft.com, Jan 8, 2008

  7. Do you have the Windows Firewall service disabled on all the servers
    including the SBS (it almost has to be disabled on the SBS with ISA, but
    check the others)? That could (will) block RPC. And sorry to be
    repetitive, but you're sure you disabled strict compliance in the protected
    networks access rule, not the internet access rule, and also in the system
    policy, and that you clicked the Apply button afterward?

    There are serious potential issues with removing a certificate authority
    from a DC - definitely not a trivial action. Make sure to decrypt any
    EFS-encrypted files anywhere on your network first, and plan for remote
    access and other potential issues. Just personally, removing and/or
    reinstalling critical services is not something I would do in the absence of
    a specific diagnosis that called for this action. I'm a lot more likely to
    blame ISA or a Windows Firewall before certificate services, which seems
    like it logically can not be the cause of anything like your other RPC
    issues.

  8. Hello Customer,

    Thank you for your reply.

    I know you have ISA server 2004 on your SBS, and you performed the Uncheck
    "enable strict RPC compliance" on ISA steps. However, the steps have not
    effect. So I think this is not a ISA related issue.

    I still suggest you perform the steps in my previous reply:

    1. Delete Certification related services from SBS
    2. Disable firewall
    3. Remove one IP address from internal NIC

    If we cannot resolve the issue after we perform the above steps, please
    help me collect some information for further investigation:

    1. How do you connect the windows 2003 R2 to SBS? Please let me know the
    network topology.

    2. Run command "ipconfig /all > c:\ipconfig_R2.txt" and "route print >
    c:\route_R2.txt" on windows 2003 R2, send the files c:\ipconfig_R2.txt and
    c:\route_R2.txt to me at

    I hope these steps will give you some help.

    Thanks and have a nice day!

    | These RPC Issues existed before we installed Certificates Services and
    | before we had any R2 Servers on the network. They are just compounding
    the
    | problem. Our SBS 2003 server has ISA 2004 installed so maybe that helps.
