Windows Server 2016 Hyper-V “password is not correct” to Synology share

July 17, 2017 Leave a comment

I could not get Windows Server 2016 Hyper-V (10.0.14393) in a WORKGROUP to authenticate to Synology SMB share if the Synology unit (DSM 6.1.3-15152) is set to maximum SMB version 3.  I kept getting error: “System error 86 has occurred. The specified network password is not correct.” (86 == ERROR_INVALID_PASSWORD), on the Hyper-V system.  I retried typing the username and password, many times, all with the same error even though I knew the username and password were okay because I could use the same share from a Windows 7 and a Windows 10 machine. I never saw any errors in Synology’s log or in Windows event viewer about this.

I had to go back to SMB 2.0 on Synology– in DSM, Control panel > File Services > SMB > Advanced Settings > “Maximum SMB” set to SMB2.  Then Windows Server 2016 Hyper-V Core would connect to the Synology share.

“No valid certificates were found on this smart card”

June 30, 2015 Leave a comment

At work we use smart cards for TFA and largely for accessing company resources remotely.  I’m currently using a Gemalto .NET smart card with an OMNIKEY Cardman 6121—a SIM-sized SC plugged into a USB dongle which is more convenient than the older full-sized SC and wired Omnikey 3021 used previously.

For years this setup has been fine.  Connect to work from home, when certificates expire renew them, and when the card runs out of space delete the expired certs.

However a few months ago I started seeing the following error instead of getting prompted for my PIN:


No valid certificates were found on this smart card. Please try another smart card or contact your administrator

The same smart card still worked on my laptop and on other PCs so it wasn’t a matter of a expired certs.  But complicating matters was that my home PC’s TPM, of which I had stored virtual smart cards, had those same certs expire roughly around the same time and the error “No valid certificates” can be interpreted as (I feel) “we found certs, but none of them are valid” so I spent some extra cycles making sure all my certificates were updated and valid instead of finding the real problem.  (And between then and now I also updated the same system to Windows 10 which would explain the difference in screenshots)

After putting the problem aside for a while, I eventually noticed my working laptop was using the Gemalto mini-driver version and the system which didn’t work was using version  I installed the Gemalto version from the Windows Driver Catalog but whenever I selected the driver for the card it would update back to and because I was busy with other things at the time I didn’t really press on it.


 .NET Gemalto search on the Windows Driver Catalog (to install, download a cab locally, unpack it, and right-click the .inf and select “Install”)

However when I went to enumerate the certificates on the card via command `certutil –scinfo > scinfo.txt` instead of getting a PIN prompt the certificates I got this error instead:


The smart card cannot perform the requested operation or the operation requires a different smart card

and the scinfo.txt output file indicated failures reading the key container when the same operation succeeded on my laptop:

================ Certificate 0 ================
--- Reader: OMNIKEY CardMan 6121 0
--- Card: Axalto Cryptoflex .NET
Provider = Microsoft Base Smart Card Crypto Provider
Key Container = (null) [Default Container]
Cannot open the AT_SIGNATURE key for reader: OMNIKEY CardMan 6121 0 …

Knowing the key container is read/written to by the mini-driver, failure to read then still hinted at some incompatibility with the particular Gemalto mini-driver version I had installed.

So I went back to Device Management (devmgmt.msc) and selected the Gemalto IDPrime .NET Smart Card node under the Smart cards node.  From there I selected “Update Driver…” > “Browse my computer for driver software” > “Let me pick from a list of device drivers on my computer” and chose the previously-installed driver version:


Now when authenticating I can see the smart card LED blinking finally indicating activity and eventually the familiar PIN prompt:


Hooray, I can work from home again.

Enable touch on HP 2740p with Windows 8.1

January 25, 2014 4 comments

After upgrading my HP 2740p from Windows 8 to Windows 8.1 I lost touch.  The Wacom pen input still worked.  I re-installed PenTablet_533-3.exe and Wacom Digitizer Driver – sp52863.exe (in that order) but touch wasn’t restored.

It wasn’t until I opened Window’s Control Panel, searched for Touch, launch the Touch Settings app, and run through the 16-point calibration was touch restored.


Touch Settings v3.0.7-24

Touch Settings (WTouchCPL.exe) on my system is installed to C:\Program Files\WTouch
