Key notes

Cisco AnyConnectis a complex VPN tool that helps remote workers access enterprise resources in a secure, effortless manner, from any supported device.

This software utility also integrates advanced protection in order to block malware at endpoints, thus ensuring a safe work environment.

Despite Cisco AnyConnect’s straight-forwardness, certain users reported having a difficult time while trying to install or launch the program.

To be more specific, during installation or while trying to launch Cisco AnyConnect, users would be prompted with an error message:

VPN client agent was unable to create the interprocess communication depot.

As it turns out, this issue is not uncommon and has a couple of easy-to-follow fixes. Check them out below:

Conclusion

All things considered, it’s easy to see that both solutions revolve around disabling the Internet Connection Sharing feature.

Most of the time, disabling the ICS straight from the shared connection should restore Cisco AnyConnect’s functionality.

However, if the issue has deeper roots, you may need to get your hands dirty and disable the ICS service altogether.
