Possible to Manually install WLAN services on Server 2012?

[SirEvan]

I have 2012 setup in my lab at home, and wanted to try link aggregation using two NICs using a program called Connectify Dispatch, which requires WLAN services to be installed. I tried to install WLAN services, but after a reboot, it always says "Failed to update Windows updates, rolling back changes" or something to that effect. I have tried a "clean boot" (disabling services and start up items) as well as trying to install in safe mode, but can't get it to work. As a test, I re-installed 2012 in a Hyper-V VM and was able to install WLAN services there. I've checked for file corruption by running SFC /SCANNOW, chkdsk, and making sure windows updates were up-to-date.

Short of running something like process explorer and watching what gets changed when installing the WLAN features, is there an easier way to copy needed bits from the VM to the host, or would it be easier to just re-install the OS? Technet forums show nothing else besides clean installs or safemode/clean boot installs, so I'm out of options besides trying to manually copy files across, or to possibly try linking the host with the VM in server manager and installing that way, although i don't know if it gets the feature bits from the box it's installing on or the machine doing the installing.

I'm not totally against a re-install, since all apps are in Hyper-V Vm's on a RAID array, so it would not be too difficult to do a re-install.

You may be stuck with a reinstall. I think you have some slight corruption in your side by side assembly database, and SFC cannot fix these issues. Your other option is to report the issue to Microsoft, and hope they release a "System Update Readiness Tool" for Server 2012 that can correct these problems.

 

I have the same issue on a Hyper-V/RemoteFX test server and have not found any other way to resolve the issue except to reinstall. I cannot add or remove roles, or install some of this month?s Windows Updates.  Since it?s only a few days until the Server 2012 R2 beta comes out, and this is my personal desktop and not a production server, I'm just waiting for that.

 

 

The only other way you can fix the problem is to figure out exactly where the corruption is within the SXS folder and replace those items from another server.  This can be difficult if the SFC tool doesn't report what descriptor is corrupt.

Hey, The System Update Readiness Tool functionality is built into DISM in Windows 8/2012! This may very well fix your problem.

DISM /Online /Cleanup-Image /RestoreHealth

Just a heads-up - you CAN team disssimilar adapters in either Windows 8 or Server 2012 - at one point I teamed a gigabit and a wireless (G in this case) adapter.

 

While similar-bandwidth teaming is preferred (as is the case with any teaming solution), Windows Server 2012 was the first non-Linux/UNIX/BSD server OS I'd any experience with to allow wired/wireless teams.
