Four times out of five when trying to connect with the VPN client on Vista Business I get a message that the Virtual adapter cannot be enabled.
When checking the logs there are two entries that always is seen together with this failure:
123 09:21:36.026 12/27/07 Sev=Warning/2 CVPND/0xA3400015
Error with call to IpHlpApi.DLL: unable CreateUnicastIpAddressEntry, error 0
129 09:21:55.709 12/27/07 Sev=Warning/3 CVPND/0xA340001A
Failed to find VA MAC Address
Anyone else who have seen this issue on Vista?
