Weak and Strong Host Behavior in Windows for multihomed Computer

Weak and Strong Host Behavior in Windows
Windows XP and Windows Server® 2003 use the weak host model for sends and receives for all IPv4 interfaces and the strong host model for sends and receives for all IPv6 interfaces. You cannot configure this behavior. The Next Generation TCP/IP stack in Windows Vista and Windows Server 2008 supports strong host sends and receives for both IPv4 and IPv6 by default on all interfaces except the Teredo tunneling interface for a Teredo host-specific relay. Figure 4 lists the commands that you can use to configure send and receive behavior for both IPv4 and IPv6 on a per-interface basis. Note that InterfaceNameOrIndex is either the name of the interface from the Network Connections folder or its interface index. You can obtain the interface index of an interface from the display of the command:
 
 Commands to configure strong and weak send and receive behavior
• netsh interface ipv4 set interface [InterfaceNameOrIndex] weakhostsend=enabled|disabled
• netsh interface ipv4 set interface [InterfaceNameOrIndex] weakhostreceive=enabled|disabled
• netsh interface ipv6 set interface [InterfaceNameOrIndex] weakhostsend=enabled|disabled
• netsh interface ipv6 set interface [InterfaceNameOrIndex] weakhostreceive=enabled|disabled
 
netsh interface ipv6 show interface

MailboxServer is partially configured – ExBPA


When running ExBPA against an Exchange 2007 mailbox server, the following error text may be noted:
===========================================================

Error: 'MailboxServer' is partially configured
Server: <SERVER>

'MailboxServer' is partially configured on server <SERVER>.contoso.com. Either setup is configuring it right now or setup failed while configuring it. Please rerun setup if it isn't currently running.


Or if you tried to install some third party application that require mailbox role installed, you may get message that you cannot install the the application since there is no mailnox role installed though you know your mailbox server functions very well


Cause: Once you intially ran Exchange Setup, setup might failed and you fixed the error and installed the mailbox server sucessfully.


Resolution: Make sure your mailbox server role works properly and then using regedit


[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Exchange\v8.0\MailboxServer]
"Action"="Install"
"Watermark"=REG_SZ:7448a073

"UnpackedVersion"=REG_SZ:8.3.83.6


remove "Watermark"=dword:7448a073


Remove "Action"="Install"


Add


"ConfiguredVersion"=REG_SZ:8.3.83.6


After, we will see


"ConfiguredVersion"=REG_SZ:8.3.83.6

"UnpackedVersion"=REG_SZ:8.3.83.6


your mileage may vary for the version value:


runn ExBPA against the Exchange 2007 mailbox server again, you should be fine.
