Cisco AnyConnect Secure Mobility Client - VPN service not available. The VPN agent service is not responding

Sometime there may be a possibility that Cisco AnyConnect Secure Mobile Client can crash and service will be continuously crashing if you go and see it in services.msc. I faced this issue when my laptop was shutdown forcefully and below I listed the resolution I found.. Client Version:  3.1.04049 Resolution: Open the browser you have been using. From the options, delete the complete browsing data stored.  Then I found that service was crashing but it gave me a couple of secs opportunity to enter my password to connect to my VPN. I entered my password quickly and then I was successfully able to connect to the VPN and didn't face this issue again. Stupid resolution but still it may be useful for few more people here..

OS Installation getting stuck at "Completing Installation" phase

I was getting the error as mentioned in the title of the post. And leaving the installation for even 10 hours didn't fixed the issue for me. So what I did is just removed all the external monitor connections and all the USB connections once the system restarted for the first time and yes I succeeded :)

Camera not working when we install Windows embedded 7. usbvideo.sys is missing

When we are using any Windows embedded template like Application Compatibility, there is every chance that camera may not function properly after the installation is done. Reason: 1) Drivers not getting installed properly or missing drivers. 2) Check if usbvideo.sys is available in %dir%\Windows\system32\drivers . If the driver is missing then that means you may haven't connected camera while installing the OS. Even if you have this file that doesn't mean camera will work properly. You need to have this usbvideo.sys file and we need to install proper drivers. Solution: Connect the camera when you are installing the image. This may give good result but if this is not working then follow the below procedure. 1) Install Windows Embedded 7 toolkit on a Windows 7/XP machine 2) Open Image configuration editor from All Programs -> Windows Embedded standard 7 3) Create a new answer file 4) In the new answer file, select application compatibility as default (from the...

System.ServiceModel.AddressAccessDeniedException: HTTP could not register URL http://+:8000/... Your process does not have access rights to this namespace

When you get the error as mentioned in title. Please check the below things: WCF service has to run as administrator If you want to run this service locally then we can workaround this error. For this please follow the below blog: http://blogs.msdn.com/b/avkashchauhan/archive/2011/03/22/opening-an-internal-http-endpoint-with-wcf-servicehost-basichttpbindings-may-cause-system-net-httplistenerexception-system-servicemodel-addressaccessdeniedexception.aspx But the catch here as the blog says, it is totally internal to the machine. External WCF clients cannot communicate with this WCF service. If you are logged in as Local user in the machine. Then run the application in elevated mode to avoid this error.

Access Edge service failed to start: Transport TLS has failed to start on local IP address

When we get the below errors in the event viewer on the edge service: A configured transport has failed to start. Transport TLS has failed to start on local IP address 10.x.x.x at port 5061. Cause: Configuration error, low system resources or another program is using the specified port. Can also happen if the IP address has become invalid. Resolution: Ensure that the IP address specified is valid and that no other program is listening on the specified port. Unable to bind for socket. Transport:TLS, IP address: 10.x.x.x, Port:5061. Error:0x80072741 (The requested address is not valid in its context.). Resolution: Ensure that no other program is listening to the specified port and that the IP address is valid. Then most probably the error can be that your IP address got changed and the topology builder is still using the old IP address. This can happen when you are using DHCP instead of static assigning. Resolution: Change the IP in the topology using the topology build...
