http://forums.windowsvistamagazine.c...post/2062.aspxRun secpol.msc
Go to: Local Policies > Security Options
Find “Network Security: LAN Manager authentication level”
Change Setting from “Send NTLMv2 response only”
to
“Send LM & NTLM - use NTLMv2 session security if negotiated”
It worked fine on my Vista Bussiness
