I was trying to install Exchange 2013 SP1 on a freshly installed Windows 2016 server when I received an error running the readiness checks.
The Windows component Server-Gui-Mgmt-Infra isn’t installed on this computer and needs to be installed before Exchange Setup can begin.
For more information, visit: http://technet.microsoft.com/library(EXCHG.150)/ms.exch.setupreadiness.ServerGuiMgmtInfraNotInstalled.aspx
When clicking on the link for more information I received the most helpful information “Sorry but we have added content for this Exchange 2013 readiness check yet”.
After double checking everything I found out Microsoft Exchange 2013 is not support on Windows Server 2016. Windows Server 2016 only supports Microsoft Exchange 2016 CU3 (and presumably later).
Looks like a new server install with a downgrade to Windows 2012 R2.
I hope this post helps someone find a quick answer to the issue rather than trawling the internet for hours.
I have just been looking at a problem with IIS (OWA outlook web access and sharepoint http://companyweb were not responding) and remote access to the RDS server had stopped. The application event log was full of event ID 1500 and 1501 for the user spwebapp.
The Windows SBS 2011 is running Exchange/OWA and IIS and has the remote gateway configured to redirect to the RDS server.
I restarted the remote gateway service which fixed the remote access problem.
The next problem was OWA and Company web not responding. I restarted IIS by running the IISreset from an admin command prompt but this didn’t change anything.
As you can see the event were happening frequently (about 20 a second). I have no idea when this started as the log was full and overwriting older events.
Recently I’ve come across a new PCI compliance failure “Web Application Potentially Vulnerable to Clickjacking”.
What is Clickjacking ?
Clickjacking uses IFrames to basically put a tranparent layer over a website and therefore can hijack the clicks and keystrokes the user enters. This is also known as a “UI redress attack” as it is changing the Users Interface.
I had a bit of a worrying time last week when a colleague upgraded an old (but live) Dell PowerEdge R310 server running Hyper-V with some new RAM.
He powered down the old server, upgraded the RAM and booted the server back up.
A few minutes later he was looking at the screen loading windows, when it failed. He put the DVD and tried to repair windows but when he got to the System recovery window it didn’t show any installations of Windows.
He then looked to restore from backup to another server to get the Hyper-V clients running while we fix this server.
Yes, you know what’ coming here, the latest backup we had was over a year old. Our client had not swapped out the drives for that length of time and something had corrupted the one drive that was plugged in. Windows Backup was reporting successful backups, but when you try to restore, you cannot see any dates to select from. An investigation for another day I think !
