Welcome to the club, buddy, and my HELL. I've been going at it for months,
f*ing MONTHS. I've tried everything you have plus many registry edits and
netsh commands, and Vista STILL refuses to cooperate, maybe we should start a
support group...
Anyway here is what someone suggested to me, it didn't work for me, but
maybe it will work for you:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Uuups -- after several weeks I finally found two small registry patches that
solved the problem thanks to the hints on PChuck's Network:
(a) (That's possible the most important one when using fixed IPs) Got to
HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Control \ Lsa \
There you either find or have to create "LMCompatibilityLevel" as REG_DWORD.
Enter 1 as value on all computers in your network. That instructs your
computer to use NTLMv2, where possible, but to also accept older auth methods.
(b) (Important if you use a DHCP server to assign the IP addresses of your
workstations) Got to:
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ Tcpip \
Parameters \ Interfaces \ {GUID}
(where {GUID} means your active network card, just bwrowse through your few
entries till you got it)
There you either find or have to create "DhcpConnForceBroadcastFlag" as
REG_DWORD
Enter a value of 0 -- this way Vista does not use DHCP broadcast if your
router doesn't support it.
After a restart I could connect to my XP Pro SP3 workstations again.
Sincerely,
Therese

You can also try resetting the Winsock and/or the TCP/IP stacks in Vista:

Resetting the TCP/IP stack:

These steps showed promise, but it ended up not working for me.
Also see if you can ping both machines from one another.
If no one here can/wants to help you, try asking here:

it to work.
