Ok I'm stump It Windows 7 keeps throwing up 0x80070035 when I try to map-network! I've tryed this. Open the Control Panel 2. Switch to "Classic" view 3. Double-click Administration Tools 4. Double-click Local Security Policy 5. Or Secpol.msc 6. Expand "Local Policies" and select "Security Options" 7. Alternate : Type secpol.msc to get editor up then 8. Locate "Network Security: LAN Manager Authentication Level" in the list and double-click it. 9. Change the setting from "Send NTMLv2 response only" to "Send LM & NTLM - use NTLMv2 session if negotiated" 10. Network Security: Minimum session security for NTLM SSP Based (including secure RPC) Clients 11. Change the setting from "require 128 bit" to unchecked (No Minimum) 12. Click OK the real difference between vista and windows 7 procedure is 10 and 11. Does any one know why it would keep trowing up this error? It knows the mac is there but I can't map it Screen capture, it's annoying the hell out of me, I assume it's some thing to do windows 7, because the setting on the mac haven't been changed since I had Vista on here, and I mapped that fine. Any one able to give me some information or know a work around that might help? An I've cheeked all the stuff in Network Sharing center is on.
