All Barracuda SSL VPNs, firmware versions 2.3 and higher.
There may be a couple of different issues that could cause this.
Currently these are the two known problems:
1. You may have a Dokan file system driver from a third party installed. It has been discovered that Dokan breaks the use of the net use command, which we use to test for existing drives and map new ones.
The SSL VPN Agent does automatically uninstall the SSL VPN Dokan driver from firmware 2.2 and before, but it will not detect any Dokan driver installed by another third party application. Unfortunately, the only option would be to uninstall that driver.
2. WebDAV will not work correctly if the SSL Certificate has expired. If this is the case, please arrange to renew your SSL Certificate.
