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?

Hi Huseyin

Thanks for the advice but the suggested application is for Windows XP and its predecessors. I don't think that it will work in Vista and Vista should take care of repairing winsock by itself. I have tried to reinstall the client though to see if that helps.

I suggested it for resetting/repairing TCP/IP not winsock reset. I used to run it on vista and worked just fine.
