Exchange 2013 readiness check fails – The windows component Server-Gui-Mgmt-Infra isn’t installed on this computer

I was trying to install Exchange 2013 SP1 on a freshly installed Windows 2016 server when I received an error running the readiness checks.

Error:
The Windows component Server-Gui-Mgmt-Infra isn’t installed on this computer and needs to be installed before Exchange Setup can begin.

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.

Solved – Dell PowerEdge R430 and installing Windows 2016 from USB

Today I got a delivery of a new Dell PowerEdge R430 and needed to install Windows 2016 Standard on it.

I downloaded the ISO from Microsoft and created a bootable USB pen using the Windows 7 USB/DVD Download tool, but Dell’s LifeCycle controller refused to recognise the USB drive.

Dell, if you’re listening, please let us install from USB through the Lifecycle Controller !

The ISO was 5.47 Gb so would not burn to a standard DVD and I needed to deliver this server to my client the following day.

Draytek Router Firmware Damage – the router will die after reboot

If you have a DrayTek with Firmware Damage and a warning “the router will die after reboot” read on to learn how to resolve it.

I have been flashing some DrayTek routers after I received an advisory from DrayTek about new critical firmware updates.

The first few went as expected with minimal downtime until one, a DrayTek 2830, disconnected midway through the upload of the firmware.

The web page of the router came back with an error “session disconnect”.

When I reloaded the page and logged back in I got the message:

Warning: Firmware Damage!!!

You must upgrade FW immediately, or the router will die after reboot!

Event ID 1500 1501 application event log spwebapp

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.

Event Id 1500 and 1501
Event Id 1500 and 1501

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.

Windows 2012 Backup error 0x8004231F

I recently had a server that had Windows Backup failing with the error (0x8004231F) “There is not enough disk space to create the volume shadow copy on the storage location”

Windows Backup Error

All the hard drives appeared to have plenty of space and the backup drives were new and also had plenty of space.

Windows 2008 server Hyper-V host and corrupted windows install

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 !

Draytek 2820 maximum number of permitted Internet Sessions

I’ve been having some issues with a Draytek 2820 at home lately. I’d made some changes to my network and swapped out a none WiFi Draytek 2820 with the WiFi version. Whilst configuring the new router I took the opportunity to upgrade the Firmware to the latest version (3.3.7.7 , Release Jan 2016).

A few days later I started getting an error message browsing the internet:

“You have reached the maximum number of permitted Internet sessions. Please close one or more applications to allow further Internet access. Contact your system administrator for further information.”

I rebooted the router, which solved the problem, and didn’t think much of it. This happened again a few days later, so I checked the Session Limit, under Bandwidth management, and this was disabled. I did note that the message I saw in the browser was the same message that would be displayed if the Session Limit was enabled.
I tried enabling session manager and then disabling, just in case the GUI was not reporting it correctly, but still the same problem.

Windows 10 start menu critical error

I had a customer today who had upgraded to Windows 10 from Windows 7. All was going well until he rebooted and the Windows 10 start menu gave an error:

“Critical Error – Your Start menu isn’t working.  We’ll try to fix it the next time you sign in.”

Of course this was never fixed the next time they signed in, it was just kept reappearing. Continue reading “Windows 10 start menu critical error”

Outlook missing emails after being moved to a folder

OK, well todays problem I’ve not come across before is strange.

A user reports that they have moved some emails into a subfolder in outlook and they’ve disappeared. I check the folder and it’s empty. Hmm. I send a test email to the account, move it to the folder and all is good. I move the email back to the inbox and ask the user to move it. It disappears.

I then search the whole mailbox and it appears in the search results. When hovering over it I see the folder name is different to the folder name in outlook.I found the folder buried under several sub folders which contained all the emails the user had moved.

The user was happy not have lost any emails and will delete the top level folder and just use the sub-folder where the emails currently are. I checked the rules under the users profile but there is nothing set up to move emails from this folder that I can find.

I’ve not manged to replicate this and I have no idea how the user managed to create what appeared to be a shortcut.

If anyone knows please let me know.

Windows SBS 2008 server out of disk space

I’ve been seeing a lot of Windows 2008 SBS servers running out of disk space lately on the C drive.

This causes Exchange to stop working due to the “back pressure” feature, which has been the first clue to the problem. After a bit of searching I found several area’s where log files can grow.

The 4 main area’s I found are :

  1. Active Directory Certificate Services
  2. IIS Log Files
  3. SBS Data Collector log (DataserviceComponents.log)
  4. Sharepoint SQL logs

I found a great script at SBSfaqs (http://www.sbsfaq.com/?p=1598) and updated the script to include all 4 points above and be able to select which options to run.

You will need to save the 2 SQL files and the batch file to a folder called “SBS Cleaner” on the root of the E drive. Run the batch file as administrator.

Please find the code for each file below.
