Vista and LAN settings permissions

[Eiolon]

Yesterday I decided to put our first Vista PC on our network. Everything seems okay, except whenever I am logged in with a domain account (versus local user), I cannot edit the LAN settings to put our proxy info in.

Vista says to contact the systems administrator (me) because apparently I have a group policy stopping users from editing LAN settings (which I don't). My account has domain/enterprise admin permissions and it still won't let me edit.

So here is what I have:

Windows XP/IE6 computers - can edit fine
Windows XP/IE7 computers - can edit fine
Windows Vista/IE7 computer - can't edit

Any suggestions for what I can try? I am using Vista Enterprise.

Well I'll just take a wild stab in the dark on this one, lol...

Administrative Tools -> Local Security Policy
Local Policies -> Security Options
Change Network security: LAN Manager authentication level to “Send LM & NTLM - use NTLM v.2 if negotiated”

Nope, didn't work :(

The only way I've been able to do it so far is by enabling the local Administrator account or to edit IE info using MMC.

I must admit this is one area I am weak in with Vista, lol, but I saw no replies so gave it a shot. I'll keep looking into it, though, might need to know someday. I figured the auth wasn't getting through.
