AnyConnect Windows 10

AnyConnect Windows 10 Fail

AnyConnect Windows 10 fails with the newest version of the VPN client software.  After a windows update we encountered a problem when we wanted to connect to our VPN.

Patch Management and Version Control Policy

Patch management and version control policy needs to be reviewed in light of issues like AnyConnect Windows 10 failure.

The symptoms were the service was running on the client  PC (Windows 10 Pro 64 bit) and when we went to run AnyConnect, the hour class would appear but we did not get the dialog to connect to the firewall.  We also noticed there was a Microsoft update that occurred since the last time we used the program.

Based on suggestions from our provider, we uninstalled the current version the program, rebooted the client and reinstalled the current version.  The same problem occurred as before. We searched the internet, including Cisco’s trouble shooting suggestions. We found no solution, rather we see that there were a number of instances where AnyConnect Windows 10 failed.

The  problem did not exist before the update by windows.  We then did the following to fix the problem.

  • Uninstalled the current version of the program
  • Rebooted the client with a power on and off
  • Installed a prior version that worked on the client
  • Ran the program and the dialog to set up the connection came up
  • The program did an automatic update to the current version
  • AnyConnect then worked

What caused the problem

We think that with the Microsoft update some registry entry or other setting was altered or removed. The re-installation of the program with the current version did not correct the issue.  When we installed an earlier version the setting was correctly added or modified.

Lessons Learned

As a best practice, versions of programs and updates should be saved. With the constant updates by both hardware and software vendors the chance of a similar problem  occurring are high. When it is time to solve a problem,  the vendors often lack easily obtainable solutions. In our case when we talked to our providers help desk, their repsonse was that was an interesting problem and they would communicate it to Cisco if they saw several customers with the same problem.  Ergo Cisco does not know the problem exists so they will not fix the offending software.
