The NT Testing TCP Tool is a handy little tool for testing the throughput between two servers – and it’s free! It’s available to download here: http://www.microsoft.com/whdc/device/network/TCP_tool.mspx
First, you need to install the MSI on both ends – for the sake of this, say SERVER1 and SERVER2. Once you’ve installed it on the server, navigate to \Program Files\Microsoft Corporation\NT Testing TCP Tool\, you should see a few copies of the tool for different architectures. Locate the correct .exe for you architecture and rename it to ntttcps.exe. Copy this and rename it to ntttcpr.exe – these form the sender and receiver parts of the tool.
Installing Exchange 2010 Edge Server with Forefront Protection for Exchange (FPE) and Threat Management Gateway (TMG) – Part 1
I am mid-migration, in a co-existence setup with Exchange 2010, 2007 and 2003. So far the roles installed for Exchange 2010 are CAS, Hub and Mailbox on a single server. Into this mix I need to introduce an Edge Server, with message hygiene in the form of Forefront Protection for Exchange (FPE) and Threat Management Gateway (TMG) as a reverse proxy to publish OWA, ActiveSync et-al.
Since Edge, FPE and TMG can now all exist on a single 64-bit server, I will start with a clean installation of Windows Server 2008 R2, up to date with all the latest hot fixes. The server itself is nothing too spectacular, for testing purposes it has 2 virtual CPUs and 2GB RAM. It does need 2 NICs, one on the internal LAN and one on the DMZ. Since the DMZ is behind a hardware firewall, an external IP address has been mapped to the servers DMZ NIC. The server is named EDGE01.
Unable to access Outlook Web Access (OWA) after installing Update Rollup 1, 2, 3 or 4 – flogon.js errors
If you’re having trouble accessing OWA after updating Exchange 2010 with any of the Rollup packages, try this:
- Uninstall the update package from the Programs and Features control panel
- Download the package file directly from Microsoft, don’t use Windows Update
- Open a command prompt or PowerShell prompt as Administrator
- Navigate to the location of the package (.msp) and run from the elevated command prompt.
Apparently when Windows update installs the package it doesn’t run it with the elevated privileges to write to the folder in the Exchange program files – why, I have no idea!
