Disconnected Network on Domain

Guest

We have been having network issues with Vista at my company that parrallel
many of the "Network Location" issues posted in this group.

When computers are joined to my domain, they work fine most of the time.
However, sometimes they will go to the "Local Access Only" state. They have
lost a DHCP number and are now assigned the 169 address. A Reboot causes
the machine to come back. However, simply repairing the connection does not.

If we take the machine and remove it from the domain, the issue Stops. We
are thinking that this is due to Vista turning off the network location
awareness when on the domain.

Does anyone have any thought on why a domain computer would simply decide it
has local connectivity only? These are not wireless, the connection is good,
and there is not a reason to loose connection I can see.

Thanks!

Are you running windows as DHCP or router? What's the switch model #?

We have a 2003 Server runing MS DHCP. All patches are up to date.

The network itself is catalyst routers from cisco. 6500 series. The
network is a simple single domain with one address range of the form (we are
not using private addresses, this is just example.)

Address = 192.168.130.x - 192.168.131.x
Gateway = 192.168.130.1
Mask 255.255.254

Hi, similar issues:

I have an SBS SP1 domain (not R2) connected to netgear router that provides
DHCP. Six WINXPPro clients connected with no issues.

Now I am connecting Windows VISTA Business clients and having the same issue
on all:

When trying to connect no clients to the domain (lercabo.local) I get the
error message "Unable to find the Active Directory". I have correctly set up
accounts for the VISTA clients on the SBS. The only way round it is to force
the DNS entry on the client computer to the IP address of the SBS server.
Then all works fine and I am able to browse the shared resources on the
server and see all attached clients.

However, at this point IE is unable to resolve the dns of our external
website www.lercabo.com! I can resolve ALL other websites: google, msn,
yahoo, etc ... bu tnot www.lercabo.com.

This ONLY happens with my 3 new VISTA Business clients. The XPPro clients
work just fine with DNS set to automatic on each client.

Any ideas???

I've been having the exact same problem with one of my Vista PC's. Our network is a little more complicated, but basically, we authenticate through a firewall, which handles our DHCP, and the AD server is a separate device which handles our AD authentication.

The Vista machine in question is quite a powerful machine, with 4Gb RAM and an Intel Core2 CPU running at 1.86Ghz.

Vista is the 32bit OS, applied as an upgrade from XP Pro SP3, to Vista Enterprise SP1, on an MSDN license.

Occasionally, usually when explorer.exe crashes, the machine looses access to the domain and basically becomes stand-alone.

To fix it, I drop it out of the domain, to a workgroup, reboot, then log it back into the domain. It works fine after this.

Until the failure happens again. It can happen on startup, so it's not always due to a failure of explorer.exe

Does anyone have any suggestions?

To whom are you talking and about what?
The "forum" that you are posting in leaches off the Microsoft News servers
in order to make it look far busier than it really is. Everyone who uses the
MS News servers sees your post on it's own - we have NO IDEA what you are
talking about and to whom you are talking.

This is not your fault - the fault lies with the forum owners who do not
explain to members that their posts end up on global Usenet newsgroups.
If you MUST continue to post in this "forum" then please at least quote the
post you are replying to, and do NOT change the subject line.

You would be far better off however, using a news reader and subscribing to
these news groups direct.
