Summary

During the initial installation of Internet Information Server 4.0 (IIS) onto a Microsoft Cluster Server, you normally begin installing IIS onto the first Node of the Cluster. Then you completely install IIS onto the second Node of the Cluster when prompted, and then you complete the installation of IIS back on the first Node of the Cluster.

191138 How To Install the NTOP on Cluster Server
This technique works fine initially but is not the method one would want to use if only one Node is lost in the cluster due to a disk failure or other failure of a Node. If the cluster is working properly the functioning Node should have taken ownership of the cluster and is continuing to service your system needs while the non-functioning Node is down.

This article contains a list of steps that can be followed to reinstall Windows NT Option Pack onto a non-functioning Node once it has been repaired. This will preserve your existing build of IIS on the functioning Node so that you can use it as a template to reconfigure the Web and FTP information on the non-functioning Node.

There is an alternative reason why you might need to install IIS 4.0 onto a single node in a Cluster. It is possible to corrupt IIS on one node of a cluster without corrupting IIS on the other node of the cluster. If you feel that it is necessary to install IIS 4.0 onto a single node in a cluster because of corruption of IIS on that node, then some critical steps which are different than a full rebuild must be performed on that node prior to you reinstalling IIS back onto the node.

Both a full rebuild and an uninstall and reinstall of IIS are covered in this document.

More information

It is important that you follow these instructions exactly with regard to installing IIS 4.0 back onto the single Node of the cluster. Failure to do so could result in problems with IIS cluster resources being corrupted, which would require a rebuild of IIS 4.0 on both Nodes of the Cluster. This problem will not occur as long as you follow the steps exactly as written.

Installing IIS onto a Newly Rebuilt Cluster Node

The proceeding steps assume that you had to rebuild one of the Nodes of your cluster, due to a catastrophic failure of the Node. Since that failure you have repaired the problem, reinstalled Windows NT 4.0 Enterprise Edition onto the system, applied the same Windows NT 4.0 Service Pack currently installed on the functioning node and have rejoined the rebuilt Node back into the original Cluster that it belonged to. If this is indeed the case then you can proceed to the "Steps to Reinstall IIS 4.0 onto a Single Node of a Cluster" section and begin installing IIS 4.0 back onto the new Node.

Removing and Reinstalling a Corrupted version of IIS on a Single Cluster Node

To reinstall IIS 4.0 onto a single node in a cluster it is necessary to uninstall it first. Use the following steps to uninstall IIS4 from the cluster node.
  1. Stop the Cluster Server Service on the Node that you want to uninstall IIS4. This can be done by stopping the Cluster Server Service from the Services Applet in Control Panel. After you Stop the Cluster Server Service, set the Startup Type for the Cluster Server Service to manual.

    IT IS EXTREMELY IMPORTANT YOU DO NOT PROCEED UNTIL YOU ARE CERTAIN THAT THE CLUSTER SERVICE IS STOPPED ON THE CLUSTER NODE YOU INTEND ON UNINSTALLING IIS 4.0 FROM.
  2. From the Control Panel Add/Remove Programs Applet chose Windows NT 4.0 Option Pack and then click Add/Remove. In the Windows NT Option Pack Setup Program Window choose Remove All. Because the IIS build is corrupted you may see some errors pointed out during the uninstall process. These errors can be ignored.
  3. After IIS has been removed you should restart the Cluster Node. If Service Pack 4 or greater is on the Node, then you should re-apply the Service Pack before proceeding.

After you have uninstalled IIS 4.0 from the single cluster node you can follow the steps below to reinstall IIS 4.0 back onto the single node and re-cluster IIS.

Steps to Reinstall IIS 4.0 onto a Single Node of a Cluster

  1. Make certain that the Cluster Server Service is STOPPED and set to Manual Startup before you proceed. You can stop the Cluster Server Service through the Services Applet in Control panel. You should also set the Startup Type for the Cluster Server Service to Manual.
  2. Run the Windows NT Option Pack Setup.
  3. It is important that during the setup of the Windows NT Option Pack you choose the exact same installation method, Minimal, Typical or Custom that was used during the original installation of IIS onto the Cluster Server. For example, if you did a Custom install of IIS on the Cluster originally and unchecked Index Server and SMTP, then you want to also perform a Custom Install of IIS on the single Node choosing to uncheck the Index Server and SMTP.
  4. Once the installation of the Windows NT Option Pack is completed you should restart the node you just installed onto.
  5. If you have Windows NT Service Pack 4 or greater on the system then you should reapply that Service Pack at this time and restart the Node again.
  6. You can now re-enable clustering on this Node. In the Services Applet in Control Panel chose the Cluster Server Service and click Start. Then change the Startup Type back to automatic.

This completes the re-installation of IIS 4.0 back onto the single node of the cluster server. Perform the remaining steps to re-cluster the node you just installed and resynchronize the IIS 4.0 settings on this node with the settings currently running on the good node.

Reclustering IIS 4.0

This section discusses the method used to recluster IIS 4.0 after performing a standalone installation of IIS 4.0 onto a single node of a Microsoft Cluster Server. When you discuss reclustering IIS what you are referring to is reclustering the MSDTC Service and re-synchronizing the metabase settings between the two nodes. If you had to completely rebuild the cluster node, then when you installed IIS onto the node with the Cluster Service stopped, the MSDTC service was installed as a standalone version and both nodes will need to have the MSDTC service re-configured. Because of this, you will have to remove the MSDTC service and reinstall it in a clustered configuration on both Nodes. This is a fairly simple process.

If you have uninstalled IIS 4.0 from a single node and then reinstalled IIS 4.0 back onto that node, then you may be able to skip this section. Normally, an uninstall of IIS will not remove the MSDTC components on the Node. To test this you should move the resource group that contains the MSDTC resource over to the second node and make sure that the MSDTC resource comes online. Before you attempt to move your IIS and MSDTC resources, make sure you configure each of the IIS Server Instances and the MSDTC resource to NOT "AFFECT THE GROUP". To do this in the Cluster Administrator, right-click on the Resource and choose properties. Click on the Advanced Tab and take the check mark out of the box to the left of the "Affect the Group" item. Do this for each IIS Server Instance and the MSDTC resource. Do not expect any WEB or FTP Instances to come online yet because we have not synchronized the metabase settings between the two nodes. If the MSDTC resource does come online on the second Node, then you can move the resource group back over to the node it came from and skip down to the section on "Configuring IIS after Installation". If the MSDTC resource does not come online then look for the appropriate installation instructions later to uninstall and reinstall MSDTC onto the cluster.

Reinstalling MSDTC onto the Cluster Server

There are two techniques that can be used to install MSDTC onto a cluster, the manual way and by running dtcsetup.exe. If you're running a Windows NT Service Pack 3 and do not have SQL 7.0 or SQL 6.5 with Service Pack 5a on the Cluster, then you will need to follow the manual installation instructions. Otherwise you can use the Dtcsetup.exe method.

  1. Installing Clustered MSDTC using Dtcsetup:

    The first step in running Dtcsetup is to obtain the appropriate Dtcsetup file for the version of MSDTC already installed on the cluster. Use the following guide to determine which Dtcsetup you need and the method used to obtain the appropriate version of the file.

    If you have Windows NT Service Pack 4, SQL 6.5 with SQL Service Pack 5a or SQL 7.0 installed on the cluster then you can download Dtcsetup.exe from:
    ftp://ftp.microsoft.com/bussys/distapps/mts/public-fixes/usa/dtc/svcpack
    Both Alpha and Intel versions of the Dtcsetup.exe can be found here.

    If you have Windows NT Service Pack 5 installed on the Cluster Servers then you will need to Contact Microsoft Technical Support to obtain Dtcsetup.exe. Request the hotfix appropriate for your platform from Knowledge Base Article Q234673.

    (THIS VERSION OF DTCSETUP.EXE SHOULD ONLY BE INSTALLED
    ON SYSTEMS RUNNING WINDOWS NT 4.0 SERVICE PACK 5)

    Once you have obtained the Dtcsetup.exe appropriate for the version that is currently installed on the Cluster Server, you can follow the following steps to reinstall a clustered version of MSDTC back onto both nodes of the cluster.
    1. Create an empty temporary directory on both nodes of the cluster.
    2. Place the Dtcsetup.exe file in the temporary directory on both nodes of the cluster.
    3. Use the MSCS Cluster Administrator to stop the Microsoft DTC cluster resource, if it is running. Stop all services that depend on Microsoft DTC.

      (including Internet Information Server, Microsoft Transaction Server, Microsoft SQL Server, Microsoft Message Queue, and Microsoft COMTI).
    4. Close Windows NT Control Panel on all systems in the cluster.
    5. Run Dtcsetup.exe on the node that owns the Microsoft DTC cluster resource. When you are prompted to install Microsoft DTC on the other nodes in the cluster, run Dtcsetup.exe on that node.
    6. Confirm that the MSDTC resource can be brought online in the Cluster Administrator and can also be brought online on the second node.
    7. Restart all services that depend on Microsoft DTC.

    Once you have MSDTC properly functioning on both nodes of the cluster you can proceed to the section "Configuring IIS after Installation".
  2. How to install MSDTC on a Cluster using the Manual Method:

    1. If there is an MSDTC resource in any of the Cluster Server Resource Groups, please delete this resource from the group that it is in. It can be in only one resource group if it is installed. If there is no MSDTC resource in any resource groups, this is OK.
    2. Close the Cluster Administrator on both nodes.
    3. From a command prompt on the working node, type the following:

      msdtc -remove
    4. From a command prompt on the node you are reinstalling, type the following:

      msdtc -remove
    5. From a command prompt on the working node, type the following:

      msdtc -install -d %windir%\system32 -l <location of DTC log file on cluster shared disk> -v <Resource Group Virtual Server Name> NOTE: Make sure that the directory you specify for the DTC log file exists on the shared disk. For example, if you entered S:\MSDTCLog for the -l variable, check to be sure an MSDTCLog directory exists on the root of the S drive. If it does not exist, create the directory before running the earlier command. The <Resource Group Virtual Server Name> refers to the value you set for the Network Name Resource in the Cluster Resource group you want to install the MSDTC resource into. For example, if you have a resource group and the network name resource has a setting of SQLVServer, you would type:

      msdtc - install -d %windir%\system32 -l S:\MSDTCLog -v SQLVServer
    6. From a command prompt on the node you re-installed, type the following: msdtc -join
    7. Before you attempt to bring the MSDTC resources online, set the MSDTC resource to NOT "AFFECT THE GROUP". To do this, Open the Cluster Administrator, right-click on the Resource and choose properties. Click on the Advanced tab and take the unselect the box to the left of the "Affect the Group" item.
    8. In the Cluster Administrator, bring the MSDTC resource online. Then move the MSDTC resource to the other node to make sure it comes online there as well. Move the MSDTC resource back to the first node.
    9. If the MSDTC resource does not come online, check the event viewer on both nodes for errors.

    Once you have MSDTC properly functioning on both nodes of the cluster you can proceed to the "Configuring IIS after Installation".

Configuring IIS after Installation

It is necessary to set certain IIS parameters when installing IIS onto a cluster. This section addresses each of those parameters. Perform each item in the list to ensure that you're IIS installation on this node in the cluster is properly configured to handle fail-over of you're Web instances.
  • Make sure that the primary copy of IIS is properly configured for MTS Replication. Perform the following steps on the active cluster server node.
    1. Open the Internet Service Manager.
    2. Double-click on Microsoft Transaction Server.
    3. Double-click on the Computers Folder.
    4. Right-click on My Computer.
    5. Choose Properties.
    6. Click on the Options tab.
    7. In the Replication Share box, place the administrative share where the \Program Files\MTS directory resides on the target server. For example: If Transaction Server was installed to the C:\Program Files\MTS directory then you would put C$ in the Replication Share box on the Options Page. In the Remote Server Name box, place the NetBIOS name of the other node in the cluster. (For example, On Node1, put the name of Node2. On Node2, put the name of Node1).
  • Once you are certain that MTS Replication is properly configured on the Primary working cluster server node then you can open a command prompt on this same Primary working cluster server node. Be certain to use cmd and not command to open the command prompt with. Change directory to \winnt\system32\inetsrv.
    Then type the following command:

    IISSYNC <Netbios Name of the cluster node you just rebuilt> IISSYNC will replicate the IIS and MTS settings from the currently running good copy of IIS to the new installation of IIS you just installed.

    DO NOT RUN IISSYNC FROM THE NEW INSTALLATION OF IIS YOU JUST INSTALLED. MAKE CERTAIN THAT IISSYNC IS ONLY RUN FROM THE WORKING IIS NODE IN THE CLUSTER.

    After IISSYNC completes, it should quit with a status code of zero. If you do not get a status code of zero, then you did not get a successful replication of your IIS and MTS settings. Refer to the following article for common IISSYNC status codes to correct the problem and run IISSYNC again.
    224801 Deciphering IISSYNC Status Codes
  • After IISSYNC has replicated the IIS and MTS information, you should check the following items to make sure that permissions for the IUSR and IWAM accounts are properly configured on the new installation. When you first installed IIS onto the cluster you should have created a Domain account called IUSR_CLUSTER and IWAM_CLUSTER (you may have chosen different names). These accounts should be used instead of the default local accounts IUSR_<MACHINE NAME> and IWAM_<MACHINE NAME> that get created during an IIS install. The following steps will assist in confirming these Domain Cluster accounts are properly configured on the newly installed IIS cluster node.

    1. Perform these steps on the node you just re-installed IIS.
    2. In User Manager go to Policies / User Rights, select the "Log On Locally" and "Access this computer from network" Policy and make sure that the Domain IUSR and IWAM accounts are there. If they are not, add them.
    3. Check that both the IWAM and IUSR Cluster Domain accounts are in the Guests Local Group. If they are not, add them.
    4. Check that the IWAM Cluster Domain account is in the MTS Trusted Impersonators (or it may be named MTS Impersonators) Local Group on the Node. If it is not, add it.
    5. Check that both the IWAM and IUSR Cluster Domain accounts are in the Dcom Default Access group with Allow Access Permission and the Dcom Default Launch Group with Allow Launch Permission. If they are not, add them. To check Dcom settings launch the Dcom Configuration Window by clicking on Start / Run and type dcomcnfg. When the Distributed COM Configuration Properties window opens click on the Default Security tab. To confirm settings, click on the Edit Default button in the Default Access Permissions and the Default Launch Permissions area of the window.
At this point your installation of IIS onto the single node in the cluster is complete. You should finish up by scheduling a time, off hours, in which you can move over all IIS Server Instances in the cluster from the current active node to the backup node. Test all your Web sites to confirm they are working properly and then you can move your IIS Server Instances to which ever node you wish to use as the primary node. After you have tested your system then you should re-enable the "Affect the Group" settings you disabled earlier so that if a failure occurs your groups will be moved to the backup node.
