A quick link reference so I don’t keep having to hunt for it in the future. Finding what the current release status is for Windows Phone updates in Australia

When trying to connect to a remote Windows 10 machine using TeamViewer, you get a blank screen with the message “The screen cannot be captured at the moment. This is probably due to fast user switching or a disconnected/minimized Remote Desktop session.”
On the computer you are trying to connect to, you may see the screen appear to flicker constantly

I first had this happen on just one of my servers. It was annoying and was causing massive numbers of WMI entries in the event logs each time it happened. I tried to just stop and disable the ConfigMgr client, but it would be “reactivated” again by something. Recently at a client site I found it happening an a large number… so time to investigate.
I checked there were no push jobs running, but there was *something* causing it to repeat. Some digging later and I finally found the reason.
There is a scheduled task created by CCMSETUP to retry if it isn’t able to install correctly on the first attempt. Under some circumstances, this task isn’t cleaned up and so the reinstall keeps happening

When you need to change the location that you have been saving all your package source files, you will then need to update all the existing packages and applications to point to that new location.
This is fairly simple for Packages, but is a bit more complicated for Applications Read the rest of this entry »

A quick link for reference to what happens in Configuration Manager when all you change is an application or packages source path, but the file contents are still the same?
This is an important point to understand as it does NOT resend all the files back out to DP’s again. This means you can change where you keep your master software repository without having to worry about massive network impacts.

Lot’s of improvements including direct connections to Hyper-V guest consoles. Nice.
RDCMan manages multiple remote desktop connections. It is useful for managing server labs or large server farms where you need regular access to each machine such as automated checkin systems and data centers. It is similar to the built-in MMC Remote Desktops snap-in, but more flexible. The RDCMan 2.7 version is a major feature release. New features include: – Virtual machine connect-to-console support – Smart groups – Support for credential encryption with certificates – Windows 8 remote action support – Support for Windows 8, Windows 8.1 / Windows Server 2012, Windows Server 2012 R2

For various reasons, there are times when Active Directory may encounter a situation where multiple objects appear. The duplicates will be named with a CNF:[GUID] on the end of the name.
Here is an excellent Microsoft blog post with an explanation of why it happens and some simple commands to find these objects. It is an issue we encounter at times with Configuration Manager boundaries and slow AD replication, but could happen for many other object types also.
For a slightly simpler method, here is my approach to using AD Users and Computers to find and delete them.

While installing multiple new ConfigMgr 2012 Management Points I was seeing a non-specific failure with an error code of 1603. Much troubleshooting and any web searches later, I discovered that there were in fact three different issues across the different servers that all failed with the same uninformative error.
- HTTPS binding missing in IIS
- Old WMI information from previous CM2007 client
- BITS not installed correctly
This was really quite bizarre. When I had found the “solution” and tried applying it to other servers I found that they had a different issue, which led to a mix of all three of the above. The old WMI issue being the most prevalent.

After having a failure on many servers installing a particular component, I found the process of scrolling through the MSI setup logs looking for the error to be incredibly tedious and unhelpful.
Luckily a colleague mentioned a tip for how to fid the error which led to this awesome blog post.
Essentially, search for “return value 3″ (without the quotes) and the failing component should be just above it.
[16:07:47] The state of web site “Default Web Site” is Started.

When running the Cisco VPN client on a Windows 64bit OS, it seems to never install correctly and will fail to connect.
Secure VPN: Connecion terminated locally by the Client. Reason 442: Failed to enable Virtual Adapter
It seems to be an issue with how the installer registers the network device for the Service. It’s an old issue that has been popping up for YEARS.
